'A moral red line'? World on cusp of autonomous weapons revolution

Paris (France) (AFP) – Lethal autonomous weapons powered by artificial intelligence are set to revolutionise warfare but there is no proper regulatory or legal framework governing the new technology.

A conference starting Monday at the United Nations in Geneva will discuss how to establish curbs and prohibitions on such weapons, called killer robots by some.

But some analysts doubt the discussions at the Convention on Certain Conventional Weapons (CCW) will keep pace with the fast-changing weapons.

AFP looks at three key questions ahead of the conference.

- What are LAWS? -

Lethal Autonomous Weapons Systems (LAWS) "
can identify, select, and engage a target without the intervention of a human operator in the execution of these tasks," said Jean-Marc Rickli, head of global and emerging risks at the Geneva Centre for Security Policy.

Autonomous weapons have long existed. An anti-personnel mine "is an autonomous weapon in the sense that it explodes when someone steps on it," said Laure de Roucy-Rochegonde of the Centre for Geopolitics of Technology at the French Institute of International Relations (IFRI).

But with the proliferation of AI-enhanced drones, such weapons are now "capable of selecting and engaging a target that was not predetermined, adapting to their environment without human intervention," said Rickli.

So the critical issue for potential regulators lies in determining the level of human control over the decision to employ such a weapon.

The United States refers to an "appropriate levels of human judgement" in the use of autonomous weapons.

France maintains that a human must remain in the decision-making loop and bans "lethal autonomous weapons systems" (LAWS) but permits "partially autonomous" systems known as PLAWS.

"The human role is always ensured through what is termed 'appropriate control' by a military commander -- a concept that varies in scope depending on the system's criticality and the operational context," said Rear Admiral Vincent Sebastien, deputy director of the French defence ministry's Agency for Defence Artificial Intelligence (AMIAD).

- The ethical issues?

"We are now dangerously close to crossing a moral red line: the autonomous targeting of humans by machines," UN Secretary General Antonio Guterres, and International Committee of the Red Cross president Mirjana Spoljaric warned in a joint statement in August.

But analysts said the Geneva discussions, while important, will touch only part of the issue.

Today, the diminishing role of humans is being driven by the growing use of AI in analysis and targeting.

Rickli said the scope of the agenda in Geneva is "very narrow".

"It fails to encompass the full range of issues surrounding AI on the battlefield" -- an area where its use is expanding, particularly in target generation.

He said this was seen in the US-Israeli war against Iran this year "where the Americans engaged as many as 1,000 targets per day" inside Iran.

"There are a host of problems and unacceptable risks associated with targeting and decision-support systems," added de Roucy-Rochegonde. "Part of this debate concerns systems that are already widely deployed on the battlefield."

"What kind of human supervision is required to ensure that the operator is genuinely exercising their own judgement rather than simply providing a rubber stamp for the machine's recommendations?" she asked.

- How quickly is the situation changing?

The autonomous weapons to be discussed in Geneva are not yet in widespread use, although analysts have noted that they have been deployed by Russia in its invasion of Ukraine as well as US attacks in Iran.

But the spread is inevitable.

"Autonomy will very quickly become a reality on the battlefield," warned rear admiral Sebastien.


"Autonomous weapon systems are not part of a distant future -- a race towards greater autonomy in weapons systems is already well underway," Guterres and Spoljaric said in their statement.

Yet significant doubts and dangers remain, Dario Amodei, head of the AI giant Anthropic, warned this year: "Today, frontier AI systems are simply not reliable enough to power fully autonomous weapons."

But ultimately, the incentive for major powers is too strong.

Swarms of autonomous drones -- which "aim to neutralise an adversary through saturation" -- would be highly effective, and some states view them as a crucial strategic advantage, said Rickli.

In January, the Chinese defence ministry described swarms of autonomous drones as the "new face of warfare."

"In an era of sharp military competition, the first state to normalise fully autonomous lethal strikes will reset expectations for everyone else," said Gerald Mako, a research affiliate of Cambridge University in the Small Wars Journal.

Key Takeaways:

The brief argues that maritime electronic warfare needs an edge-deployed multi-agent architecture combining digital arrays, compressive sensing, deep learning, a domain language model and reinforcement learning to close the gap between detecting agile emitters and countering them.

It proposes specialized sensory, support, decision and attack agents running on warships and coordinated UAV swarms, with uncertainty gating and adversarial defenses to keep autonomous actions inside human-set bounds.

For India it recommends edge-hardware retrofits, open architectures, sovereign synthetic RF data, an independent red team and a joint test establishment so the system is proven against local emitters and rules of engagement.


The contest for the EM spectrum has moved from the physics of jamming to the speed of decision. An edge-deployed, multi-agent architecture that senses with a digital array, reconstructs with compressive sensing and classifies with deep learning, decides with a domain language model, and attacks with reinforcement learning can close the gap between detecting an emitter and countering it in crowded littoral waters.
Introduction

Control of the electromagnetic (EM) spectrum is no longer a supporting function of naval operations. It is the condition on which they rest. The same spectrum carries the sensors, communications and networks on which action in the sea, land, air, space and cyber domains depends, and a force that loses it fights blind and mute. Yet the maritime environments in which navies now expect to operate, such as the approaches to choke points, disputed littoral waters, and the crowded sea lanes of the Indian Ocean Region, are dense with emitters, many of them civilian and many reconfigurable in software. The volume and agility of the Radio Frequency (RF) traffic they generate have outrun both the rule-based Electronic Warfare (EW) suites built to interpret it and the human operators who supervise them.[1]


This brief argues that the gap is integrative rather than inventive. Classification, coordination, distributed attack and model robustness have each been demonstrated, and each is represented in the literature. What does not exist is an architecture that holds them together under the conditions the maritime environment imposes: intermittent connectivity, severe size, weight, power and cost (SWaP-C) limits, and an adversary who may attack the models themselves. What follows describes that architecture, the distributed platforms that carry it, the safeguards that keep it trustworthy and what India should do about it.


The Maritime Electromagnetic Battlespace

Spectral congestion in the littoral is structural, not accidental. The International Telecommunication Union (ITU) allocates the spectrum among services through its Table of Frequency Allocations, and national allocations, including India’s National Frequency Allocation Plan (NFAP), are drawn from it. Interference nonetheless arises at the edges of that framework. Many bands are shared on a primary or secondary basis, transmitters radiate beyond their assigned bandwidth through sidebands and out-of-band emissions, and a strong signal in an adjacent band can saturate a receiver tuned elsewhere. Military emissions add further complication, since not every military system operates within a civil allocation.[2]


The margin is narrower than it looks. In the United States, 5G transmissions in the 3.7–3.98 GHz band were found to interfere with aircraft radar altimeters operating at 4.2–4.4 GHz, a separation of only about 220 MHz. India’s C-band allocation of 3.3–3.67 GHz leaves a gap of about 530 MHz, and no comparable incidents have been reported here. Even so, the Directorate General of Civil Aviation (DGCA) has issued an airworthiness directive requiring radio-altimeter tolerance in Indian airspace, which treats the margin as a safety matter rather than dismissing it.[3] A warship’s electronic support receiver, asked to work in the same bands under wartime conditions, has no such protection.

The emitters themselves have changed. Hardware-defined, single-function radars have given way to software-defined Active Electronically Scanned Array (AESA) systems that can alter their operating parameters pulse by pulse, and can search, track, guide a missile and jam at the same time.[4] They radiate Low Probability of Intercept (LPI) and Low Probability of Detection (LPD) waveforms such as frequency-agile carriers, non-linear frequency modulation, pseudo-random pulse repetition interval stagger and ultra-wideband spread spectrum, distributing their energy across a wide bandwidth or below the noise floor so that a conventional receiver never registers them at all.

Against this, legacy electronic support measures are federated and hardware-centric. They capture RF energy, down-convert it, extract pulse width, time of arrival, frequency and angle of arrival, and match the result against a static, pre-programmed Electronic Order of Battle (EOB).[5] When a waveform is not in the library, two failures follow. The suite ignores the threat, or it forces the signal into the nearest entry and treats it as that emitter. The second is the more dangerous. A missile-guidance radar catalogued as a surveillance radar draws a countermeasure that has no effect, while the operator sees a track that appears to have been dealt with. Because threat libraries are built by offline laboratory analysis and updated by hand, no such system can respond to a zero-day or dynamically reconfigured waveform in real time.


A platform may face dozens of simultaneous emitters from surface vessels, aircraft and incoming anti-ship missiles, and the Pulse Descriptor Words (PDW) generated by modern wideband receivers saturate both the processing buffers and the operator.[6] Legacy suites do offer automatic modes for countermeasure selection, power assignment and effectiveness assessment, but those modes execute pre-programmed responses drawn from the same static library. With anti-ship missiles at supersonic or hypersonic speed, the response window falls to a fraction of a second, which is too short for a human to intervene and too short to correct an automatic mode that has chosen wrongly.

The operating environment compounds the problem. A contested EM environment implies intermittent or total loss of satellite and shore connectivity, whether from jamming or from cyber attack.[7] Forward units must therefore work on the principle of mission command, with authority delegated downward. The EW suite must become an island of intelligence at the edge, perceiving, deciding, and acting on local computation alone.

Table 1. The Cognitive Gap in Maritime EW

Existing approach What it delivers What remains unresolved
Rule-based EW with static threat libraries Fast, predictable and verifiable responses to emitters already catalogued Cannot classify or counter a waveform absent from the library; cannot adapt without a manual update
Machine-learning signal classification High accuracy in modulation classification and emitter identification, including at low signal-to-noise ratio Treats classification as an end in itself; no closed loop from classification to countermeasure selection
Multi-agent orchestration with large language models Coordination of distributed EW assets and reasoning over tactical options Assumes reliable connectivity and substantial computing power; untested against adversarial manipulation
UAV swarm electronic warfare Distributed jamming power; relief from the SWaP-C limits of individual platforms Addresses the attack function alone; no integrated sense–decide–act loop
Adversarial-AI defence and explainability Model robustness and transparency, considered in isolation Not embedded in an operational EW architecture; no defined handover of authority to a human operator
Source: Author’s synthesis of the literature surveyed in this brief.


No single row of the table is the problem. Classification without a closed loop to the countermeasure, orchestration that assumes connectivity it will not have, jamming without sensing and robustness designed in isolation — each solves one part of the problem while assuming the rest are solved elsewhere. The gap lies between the rows. Each gap has a corresponding answer in the design. The ES Agent’s compressive-sensing receiver and its convolutional and recurrent classifiers handle waveforms absent from the library, working from the signal itself rather than a stored template.

The missing link from classification to countermeasure is closed by the Decision and EA Agents, which turn a classification into a selected technique and then measure its effect. The assumption of reliable connectivity is removed by placing the entire stack at the edge and linking the swarm by mesh. The swarm does not decide on its own: the Decision Agent on the host platform assigns the mission. At the same time, each node executes its assigned role locally and shares track state over the mesh, so that decisions are taken where the latency budget allows and coordinated where it does not. The gap between a robust model and a robust architecture is closed by embedding adversarial training, uncertainty gating and explainability in the same agent structure, with authority returning to the operator wherever confidence falls.

A Multi-Agent Architecture for the Edge

The proposal is a decentralised, edge-deployed multi-agent system integrated into the platform’s Combat Management System (CMS).[viii] A monolithic model would concentrate failure and add latency; dividing the mission among specialised cooperative agents avoids both. The agents run concurrently on heterogeneous edge hardware and communicate over standard vehicle buses such as the NATO Generic Vehicle Architecture.

The Sensory Agent manages a multi-channel digital antenna array. Where analogue receivers scan slowly and see a narrow instantaneous bandwidth, the array samples RF directly at the element level through high-speed analogue-to-digital converters. The agent runs digital beamforming to form several independent beams at once. When it detects a jammer or missile seeker, it places deep spatial nulls in that direction, shielding its receivers from saturation while keeping sensitive beams elsewhere.

The Electronic Support (ES) Agent turns those samples into identifications. Direct sampling at the antenna produces data at a rate no shipboard processor can handle in full. Since most real signals are sparse, the receiver reconstructs them from far fewer samples than the Nyquist rate would demand, reducing converter power and computational load. Sparse Bayesian Learning performs reconstruction at the edge and does not need to be told in advance which representation makes the signal sparse.[ix] The reconstructed signal then passes through a staged pipeline. A one-dimensional convolutional neural network performs automatic modulation classification with over 90 per cent accuracy even below 0 dB Signal-to-Noise Ratio (SNR).[x] Specific Emitter Identification (SEI) maps the signal to a physical platform, and a Long Short-Term Memory (LSTM) network, trained on sequential pulse-interval data, predicts the radar’s next frequency hop or pulse repetition mode so that countermeasures can be scheduled in advance.[xi]

The Decision Agent is the cognitive core. It runs a domain-specific transformer over a Mixture of Experts (MoE) framework, sized for field conditions rather than for a data centre. A Retrieval-Augmented Generation (RAG) pipeline connected to the platform’s local signal library converts an unknown emitter’s metadata into vector embeddings and retrieves historical tactics and recommended responses. The mixture routes the threat profile to specialised models: one weighs lethality through fuzzy logic, one schedules countermeasure resources, and one deconflicts distributed assets.[xii] The computational weight of this layer is the least settled part of the design. Unlike the ES classifier, whose compression to a fraction of a megabyte is demonstrated in the literature, a Mixture-of-Experts transformer with a vector-search retrieval pipeline and three further sub-models has no comparable published footprint at the edge. Whether it can run within the power, cooling, and space available on a warship is an open question, and a prototype would have to settle it before the architecture could be fielded.


The Electronic Attack (EA) Agent executes. It uses deep reinforcement learning of the policy-gradient kind, in an actor–critic arrangement, where a learned value estimate serves as a baseline that reduces the variance of the policy update.[xiii] Operating in a continuous action space, it selects waveforms and schedules power and frequency to avoid disrupting friendly communications.[xiv] It then uses the victim radar’s own behaviour, losing track or reverting from track to search, as the reward signal that tells it whether the technique worked.[xv]

The classified element of the suite is not depicted; it sits at the interface between the Decision Agent and the combat management system, where mission data and rules of engagement apply.

Distributed Nodes: UAV Swarms in the Electronic Attack Role

A micro-UAV cannot carry the cooling, generation and aperture needed to jam a multi-megawatt naval air-defence radar. The answer is not a bigger drone but a different division of labour: a distributed autonomous system of dozens of low-cost, expendable nodes, some carrying wideband ES receivers and others low-power software-defined jammers, whose coordinated action synthesises a high-power, multi-directional attack.[xvi]

Distributed jamming also answers the counter. A single continuous jammer is a beacon for an anti-radiation missile or a passive Home-on-Jam (HoJ) seeker. A swarm can instead ‘flicker in space’, where node A radiates for a few milliseconds and goes silent, node B radiates from a different position, then node C. To the seeker, the emission appears continuous but jumps between physically separated points, so no stable track forms and the missile passes through the space between the nodes.[xvii]


None of this survives without a self-repairing network. The swarm forms a local ad hoc mesh and routes with Optimised Link State Routing (OLSR). Raw sensor data moves over the data distribution service, where latency matters most, while command messages and track states go over the lighter Message Queuing Telemetry Transport (MQTT) protocol.[xviii] The swarm also optimises its geometry, computing how sensitive the jamming effect is to each node’s position and moving the node in the direction that has the most effect for the least displacement, so it sits inside the victim radar’s main lobe or its more sensitive sidelobes.


Reading the Emitter: Radar Fingerprinting at the Edge

Specific Emitter Identification (SEI) deserves separate treatment, because it changes what electronic support can produce. No two transmitters are identical. Manufacturing tolerances, chemical variance in silicon wafers, microscopic imperfections in metal cavities and differences in transformer windings leave each unit with its own analogue anomalies.[xix] The combined effect is Unintentional Modulation on Pulse (UMOP)—microscopic ripples in the envelope and intra-pulse phase that are fixed by the physical geometry of the transmitter, and therefore stable, repeatable and very hard to counterfeit.

That signature does three things a waveform parameter cannot. It exposes decoys and radar spoofing, where an adversary mimics a friendly emission. It holds an accurate EOB even while radars are frequency-agile or operating at low probability of intercept. It converts passive detection into platform-level tracking, letting a warship isolate hostile units from the hundreds of merchant and fishing vessels around it and maintain a targeting-grade passive track.[xx]

The classical approach of hand-extracted features such as pulse rise time, settling time and envelope asymmetry is cheap but brittle. Multipath reflection, sea clutter and atmospheric fading warp the transient envelope, and accuracy falls away precisely at the ranges where the SNR drops below 10 dB. Deep networks such as Convolutional Neural Networks (CNNs) and self-attention transformer encoders fare far better, as they weigh every sample in the sequence against every other.[xxi] The caveat, however, is data. Accuracy depends on the number of observations and the number of samples per observation, and AI methods still trail classical ones in dense, low-signal conditions. Hybrid approaches are therefore the more promising near-term direction.[xxii]

More than accuracy, deployment is the binding constraint. Running these models on a warship means processing millions of pulses per second without server racks. Compression under the TinyML framework, such as TensorFlow Lite, closes the gap by quantising weights from 32-bit floating point to 8-bit integers. A baseline convolutional model shrinks from about 1.4 MB to 123.8 KB, and a transformer encoder to 73.27 KB, with no material performance loss.[xxiii]


Securing the Cognitive Suite

A suite that is autonomous but open to manipulation is more dangerous than the rule-based system it replaces, because it will act quickly and confidently on a false picture. Four threat vectors matter. In model evasion, an adversary shapes its own radar pulses so that the classifier returns a confident but wrong label, and the correct self-defence measure is never released. Secondly, in data poisoning, deceptive or mislabeled emissions radiated in peacetime enter the local training set and shift the decision boundary, leaving a trigger waveform that opens a backdoor later. In model inversion, structured probe signals and the countermeasures they draw allow an adversary to reconstruct the network’s weights and map its blind spots. Lastly, in supply chain compromise, backdoors enter through open-source libraries or pre-trained foundation models.[xxiv]


These defences applied together are proportionate. The first is RF-specific adversarial training, in which gradient-based perturbations generated by the Fast Gradient Sign Method (FGSM) are mixed into the training set, forcing decision boundaries that generalise against deception. The second is uncertainty-based action gating. Models emit a confidence or entropy measure alongside the classification; when uncertainty crosses a threshold, the suite is barred from autonomous action, falls back to a deterministic, rule-based safe state, and alerts the operator.[xxv]

Gating on uncertainty is necessary but not sufficient, because it works only where the model recognises that it is unsure; an input unlike anything in its training data, or one deliberately crafted to deceive, can produce a confident error that never trips the threshold, and a fixed floor such as 85 per cent carries the same weakness. It must therefore be paired with checks that do not depend on the model’s own self-assessment: flagging inputs that fall outside the distribution on which the model was trained, corroborating a classification against a second model or an independent sensor, and testing the deployed suite against deliberate deception rather than only against representative signals. The third is explainability. A saliency map laid over the spectrogram, or the attention weights of a transformer, shows the operator which part of the signal drove the call.[xxvi] This is not proof of why the model concluded, but where the model looked, and it serves as an aid to judgement rather than a substitute for it.


Autonomy and Its Limits

The objection to all of this is serious and should be stated in its strongest form. Deep reinforcement learning agents are probabilistic and lack formal verification, so a change of sea state or a domain shift could produce erratic jamming that disrupts friendly command links or escalates a situation nobody intended. A black-box failure cannot be diagnosed in real time, eroding situational awareness and deskilling the crew who must take over. And integrating AI merely trades conventional cyber vulnerabilities for adversarial ones, which a capable opponent can exploit to paralyse a multi-million-dollar platform. On this view, a deterministic rule-based system is slower but wholly predictable, verifiable and under human command, and therefore safer.

The rebuttal rests on three points. First, the rule-based alternative is not slow but blind: against a waveform not in the library, it offers nothing, and the certainty it provides is the certainty of not seeing the threat. Second, the choice is a false binary. Coupling deep-learning classification with deterministic safety boundaries and uncertainty gating produces a hybrid in which the AI operates inside a sandbox and surrenders control the moment confidence falls.

Third, the architecture elevates the human, rather than removing them completely. An operator freed from reading pulse trains becomes a supervisor of the machine’s reasoning rather than a component in its processing chain. This is consistent with the sub-second window described earlier only because the two refer to different decisions. Responses inside the engagement window, such as countermeasure selection and release, are automatic and bounded by the rules the operator has set in advance. Everything slower—changes to those rules, the authorisation of a new technique, the review of what the suite did and why—waits for the operator. The human supervises by setting the boundary before the engagement and auditing the record afterwards, rather than by intervening during it. The safeguard is not the existence of the mechanism but the discipline of its use, and that is a question of doctrine and training as much as of software.

Recommendations

At the tactical level, existing naval platforms should be retrofitted with heterogeneous edge accelerators such as neuromorphic processors or low-power tensor processing units that can run wideband convolutional and recurrent models locally within SWaP-C and thermal limits. Onboard, EW subsystems should adopt open-architecture interfaces such as the NATO Generic Vehicle Architecture so sensing, classification, and execution modules can exchange data at low latency. Uncertainty gating should be built into the CMS as a hard interlock, blocking autonomous jamming or chaff release and handing control to the operator whenever classification confidence falls below a defined floor. A starting point such as 85 per cent, to be calibrated through trials.

At the operational level, UAV swarms carrying lightweight software-defined cognitive payloads should be developed as forward-deployed sensing and cooperative jamming nodes for task groups, with endurance addressed through hydrogen fuel-cell propulsion. Self-healing mesh protocols should be standardised across uncrewed assets so that the local network survives jamming and node loss. No such suite should enter service without closed-loop, high-fidelity simulation that exposes the models to diverse adversarial waveforms and realistic sea-state noise.

At the strategic level, three investments matter more than any single platform. First is sovereign synthetic RF data generation, where labelled emissions from a real adversary are classified or unobtainable in peacetime. High-fidelity national electromagnetic simulators are the only way to train models before contact, and the simulator becomes a strategic asset in its own right. Second, India must establish a standing, independent RF red team, empowered to test deployed models for evasion, poisoning, and extraction both before fielding and continuously afterwards. Third, India needs a settled legal and policy position. Autonomous spectrum decisions need defined accountability, and India should shape international guidelines rather than receive them. Domestically, a joint EW test and evaluation establishment should carry these strands through the indigenisation routes already in place, so the architecture is proven against Indian emitters, Indian sea states, and Indian rules of engagement rather than imported wholesale.
Conclusion

The contest for the EM spectrum has moved from the physics of jamming to the speed of decision. Legacy suites were built on the assumption that the threat could be catalogued before the fight began, and that assumption no longer holds. An edge-deployed, multi-agent architecture that senses with a digital array, reconstructs with compressive sensing and classifies with deep learning, decides with a domain language model, and attacks with reinforcement learning offers a way to close the gap between detecting an emitter and countering it. None of it is safe unless the suite can also be trusted: adversarial training, uncertainty gating and honest explainability are not additions to the architecture but part of it. The risk of fielding such a suite is real, but the certainty of meeting agile, software-defined threats with static libraries is worse.About the author: Cdr Vishnu B Nair is a Communication & Electronic Warfare specialist, presently undergoing the 33rd Naval Staff and Technical Management Course (NSTMC-33) at the Naval War College, Goa.

Robots transform Central Europe's warehouses

Robots transform Central Europe's warehouses
LPP announced plans for Europe’s largest installation of warehouse robots capable of climbing racking systems at the logistics centre it is building in Tczew, Poland. / LLP
By Clare Nuttall in Glasgow November 12, 2026

More than 3,500 robots now carry clothes between storage racks and picking stations in Polish fashion group LPP's warehouses in Poland and Romania, travelling a combined 51,000 kilometres a day as the company automates operations to keep pace with the growth of online sales.

The robots operate on a tote-to-person model, bringing goods directly to warehouse operators rather than requiring employees to walk the aisles to retrieve them, according to Sebastian Sołtys, president of the management board at LPP Logistics. "The data speaks for itself: thanks to robotics, we have increased order-picking productivity fivefold. The sorting process itself is now up to three times faster," Sołtys told IntelliNews.

Storage racks at LPP's fulfilment centres rise to 12 metres and hold up to 250 items per square metre, compared with around 65 in a conventional e-commerce warehouse with two-metre shelving. The robotic fleet started with 555 units and expanded more than sixfold within 12 months. In October, the company announced plans for an advanced automation system at its new logistics centre being built in Tczew, Poland to handle e-commerce orders.

LPP's investment is part of a broader transformation of Central Europe's logistics sector, where warehouses once marketed primarily on cheap land and labour are increasingly becoming automated facilities run on data. As online orders grow, operators are investing in robotics to overcome workforce and floor-space constraints.

Amazon opened a 200,000-square-metre robotic fulfilment centre at Dobromierz in Lower Silesia on September 21, equipped with more than 5,000 robots across four storeys. The facility is part of the US company's pledge to invest more than €5bn in Poland between 2026 and 2028. China-based fashion retailer Shein opened a European logistics hub near Wrocław in December 2025, fitted with robotic picking systems and automated sorting lines. In Prague, online grocer Rohlik has introduced robotics into an existing warehouse rather than rebuilding it.

E-commerce drives automation

For LPP, the main driver has been the rapid expansion of online retail. E-commerce's share of group revenue has risen "from an almost negligible level to 25-30% today", Sołtys said, with its warehouses fulfilling 60mn orders in 2025 for online sales in 35 markets.

"With growth at this pace, a traditional manual warehouse simply cannot keep up," he said.

The group's changing product mix has added to the challenge. Its logistics operations originally focused largely on supplying physical shops and its Reserved brand, but growth is now driven increasingly by Sinsay, its value-oriented brand, which has a different product range and is expanding across Poland and Central and Eastern Europe.

LPP launched a Sinsay online marketplace in September, with some third-party orders expected to be fulfilled through its warehouses from early 2027. The group aims to double the marketplace's scale within three years.

"It is not possible to scale the workforce or warehouse footprint proportionally, which makes robotics and flexible IT systems critical to our growth, allowing the business to expand faster than headcount and keep pace with a rapidly growing market," Sołtys said.

Fashion retail presents particular logistical challenges, with tens of thousands of individual stock-keeping units and unpredictable demand for particular products and sizes. Traditional warehouse-management systems based on ABC inventory classification, which prioritises products according to turnover, are insufficient for LPP's requirements.

"Classic ABC inventory classification systems do not work for us at all," Sołtys said.

Rising labour costs are another incentive. Poland's rapid increases in the minimum wage are encouraging employers to invest in automation as the country loses its low-cost labour advantage. Invest in Wroclaw, the city's investment promotion agency, says local companies are increasingly turning to automation and digitalisation to maintain productivity.

"With unemployment reaching a record-low 2.5% in May 2026, warehouse operators have increasingly turned to automation and digitalisation to maintain productivity and remain competitive. As a result, modern warehouses in and around Wrocław have evolved far beyond traditional storage facilities into highly automated, data-driven operations," a spokesperson for the agency told IntelliNews. 

Wrocław emerges as a logistics hub

Lower Silesia, particularly the area around Wrocław, has become a major location for logistics investment. Situated within the Berlin-Prague-Warsaw triangle, around 150 km from the German border and 100 km from the Czech Republic, the region offers access to several major consumer markets.

It had 5.30mn square metres of modern warehouse space at the end of the third quarter of 2025, with a vacancy rate of 10.7%, according to information supplied by Invest in Wroclaw to IntelliNews. Gross demand reached around 708,500 sqm in the first nine months of the year, while online retail accounted for approximately 42% of warehouse leasing.

Base rents of around €55 per square metre annually compare with approximately €86 in Germany's main logistics markets and €90 in the Czech Republic, the agency said. The region also benefits from the A4 motorway, which carries more than 70,000 vehicles a day on its Wrocław section, and the intermodal terminal at Kąty Wrocławskie, which handles 740-metre trains with connections to Gdańsk, Gdynia, Hamburg, Antwerp and China.

Shein signed the region's largest warehouse lease in 2025, taking 79,000 sqm at ECE Kąty Wrocławskie. The company says its Lower Silesian operations support at least 5,000 jobs and involve more than 170 local small and medium-sized enterprises. The hub is intended to speed deliveries to its more than 100mn customers across Europe.

Amazon's Dobromierz facility is around 60 km to the southwest. Further west, logistics group DSV opened Poland's first multi-client warehouse equipped with the AutoStore robotic system at Goleniów Park near Szczecin in early 2024. DSV initially occupied almost 5,000 sqm when it entered the park in 2021 but has since expanded to more than 25,000 sqm.

Romania is emerging as another important distribution base. LPP's 65,000-sqm fulfilment centre at CTPark Bucharest West began shipping customer orders at the end of October 2025, following its announcement in 2023. Developer CTP completed construction in around six months. The facility can store up to 7.5mn items and process more than 80,000 orders a day, serving Bosnia & Herzegovina, Bulgaria, Greece, Hungary, Romania and Serbia.

Despite the expansion of warehouse automation, industrial robotics remains relatively underdeveloped across much of Central and Eastern Europe. Poland had 71 industrial robots per 10,000 manufacturing employees in 2023, compared with 415 in Germany, according to the International Federation of Robotics (IFR). Slovenia is the exception; the IFR's latest figures put its robot density at 315 per 10,000 manufacturing employees in 2024, among the world's 10 most automated economies and well above the EU average of 231.

Robots and artificial intelligence

At LPP, different types of robots handle separate stages of the fulfilment process. Some transport containers and stack them on high-bay racks, others retrieve them and deliver them to picking stations, while a third group sorts individual garments into customer orders. The warehouse management system tracks the location of every container, reducing errors. 

Artificial intelligence also helps determine how operations are organised. LPP's first major AI project, developed with its warehouse-management system provider several years ago, created a digital twin of a warehouse to optimise batch picking and employee routes. The system reduced employees' walking distances by almost 30% and increased end-to-end picking efficiency by 20%. It was subsequently rolled out across all LPP's e-commerce warehouses. Algorithms at the robotised sites now determine machine routes and where products should be stored.

AI is also used to forecast demand for individual products, allocate stock between warehouses and shops, and process customs, freight-forwarding and accounting documents generated by the tens of thousands of containers handled annually by LPP Logistics.

"We never lose sight of one basic rule: AI runs on data, so the data must be error-free," Sołtys said.

Similar applications are spreading across Wrocław's logistics sector. In one large omnichannel fashion distribution centre in the metropolitan area, an AI-supported warehouse-management system reduced picking routes by 30% and increased overall process efficiency by 11%, according to Invest in Wroclaw. Order picking can account for up to half of a warehouse's operating costs.

Digital twins allow operators to test changes before investing in equipment, including whether a sorting system can cope with the expected increase in orders during the pre-Christmas shopping season. Invest in Wroclaw estimates that digital twins can raise productivity by around 20% in the short term and by as much as 40% within four years.

Retrofitting existing warehouses

Rohlik's experience shows that automation does not necessarily require a purpose-built facility. The Czech online grocer's Horní Počernice fulfilment centre in Prague processes around 7,000 orders a day and stocks 18,000 stock-keeping units across ambient, chilled and frozen zones, according to an IFR case study published in December 2025.

Rohlik worked with Slovak robotics company Brightpick to automate the first floor of an existing three-storey mezzanine in the ambient storage area. Autonomous mobile robots retrieve containers and bring them to robotic picking arms, which use 3D scanners and AI to identify products. All 2,500 stock-keeping units in the automated area were suitable for robotic picking, and the system was designed to handle 600 picks an hour.

Rohlik retained its existing two-metre shelving, avoided the capital expenditure involved in rebuilding the warehouse and installed the system within weeks without interrupting operations. It also maintained the delivery speeds behind its promise to deliver orders within 60 minutes.

"Before installing Brightpick, our picking process was entirely manual. Brightpick enabled us to install end-to-end automation without making any major changes to our existing warehouse processes. Their solution enabled us to practically eliminate our picking labor and reduce picking costs," said Aleš Malucha, Rohlik Group's chief engineering officer.

The contrasting approaches are creating new requirements for industrial property developers. Warehouses increasingly need reinforced floors, sufficient electrical capacity and layouts that can accommodate robots, including when tenants introduce automation years after moving in. 

"The market is ... seeing growing demand for specialised Built-to-Suit (BTS) and Built-to-Own (BTO) facilities," Invest in Wroclaw's spokesperson told IntelliNews. "Rather than leasing standard speculative warehouse space, companies in the automotive, electrical engineering and pharmaceutical industries increasingly prefer facilities designed specifically for their operations, incorporating dedicated automation zones, reinforced floors and advanced climate-control systems from day one."

The pace of technological development has accelerated. When DB Schenker introduced its first logistics robot in the Czech Republic at Pardubice in October 2020, it was a single autonomous trolley tug. More recently, Rohlik says it integrated AutoStore robotics into its warehouses in eight months, compared with the two to three years typically required by the industry.

Investment depends on returns

LPP invested PLN1.7bn (€385mn) in logistics infrastructure in 2024-2025, and its robotics programme is delivering returns within its planned three-year payback period, Sołtys said.

"We seek scalable one-to-many solutions. That is why we have adopted advanced robotics and automation in our Fulfilment Centres, targeting a three-year payback period," he said.

However, the company is holding back from technologies that have yet to demonstrate sufficient returns, including humanoid robots and automated container-unloading machinery.

LPP conducted a 20-hour trial of a robot designed to transfer goods onto a conveyor belt. Within the first 10 hours it was already less efficient than a human operator, while regular charging, battery replacements and technical support added to the costs. Trials of container-unloading robots produced similar results. A machine would replace only one employee, while software, servicing and maintenance made the payback period too long.

LPP prefers to be an early adopter rather than a pioneer, waiting for proof-of-concept tests before rolling out technology across its network, Sołtys said. A sorting function it developed with a supplier was subsequently patented by that supplier.

Rohlik has also reported gains from its software investments. Its in-house warehouse control system, Arcos, determines which container to retrieve, how to pack products and which orders to prioritise. The company says it delivers around 10% greater efficiency than comparable systems on the market. Rohlik doubled its engineering output between November and August after introducing AI coding agents, according to a case study by US developer Cognition. Around 30% of its use of the Devin AI agent involves data analysis by business employees.

More broadly, the business case for automation depends on order volumes, wages, inventory complexity, integration costs and reliability, as well as whether systems can be replicated across multiple facilities. LPP introduced its robotic fleet across several sites in just over six months, compared with the 12 to 18 months normally required for projects of this type, Sołtys said.

Changing warehouse jobs

Automation has not necessarily reduced employment at the large new distribution centres. Amazon expects its Dobromierz facility to employ more than 1,000 people by the end of 2026, while Shein says its Lower Silesian operations support at least 5,000 jobs.

At LPP, robots bring goods to ergonomic workstations, reducing the need for employees to walk long distances through warehouses. This cuts physical strain, improves safety and reduces mistakes, Sołtys said. The company is also investing in employees' analytical skills, as managing automated operations requires staff able to interpret data and coordinate robot fleets.

Invest in Wroclaw expects demand to grow for specialists in AI systems management, robotics configuration, AI training and technology-related health and safety.

At Rohlik, AI agents have expanded beyond software engineering into warehouse administration and operational planning. They can prepare claims against suppliers over faulty deliveries, follow up invoices and improve workforce planning by estimating potential employee absences ahead of long weekends.

The technology is also changing the skills required of engineers. Whether productivity gains translate into higher wages and better working conditions, how much retraining employees will need and how closely workers will be involved in decisions about automation remain open questions.

Southeast Europe looks to the next phase

The expansion of automated logistics in Poland and Romania raises the question of whether Southeast Europe will follow as demand for modern industrial space increases.

Joanna Sinkiewicz, CBRE's head of industrial and logistics for Central and Eastern Europe, told IntelliNews that manufacturing remained the main source of demand for industrial space in Southeast Europe, with e-commerce a smaller but rapidly growing segment.

"The SEE region is inquiring for production. After pandemic and war disturbance in supply chain, a lot of manufactures have decided to redesign their supply chains and more often consider CEE region as the location for their new production facilities," she said.

Romania, Croatia, Serbia and Bulgaria stood to benefit from nearshoring because of labour availability, operating costs and proximity to European markets. Croatia and Slovenia were also attracting tenants through their access to the Adriatic ports of Rijeka and Koper.

Przemysław Piętak, CBRE's supply chain advisory director, highlighted the region's position between Europe, Asia and the Middle East, pointing to the ports of Constanta, Koper and Rijeka as important entry points for goods entering Europe.

"In the rapidly evolving global supply chain landscape, locating warehousing and manufacturing projects in Southeast Europe presents a compelling proposition, offering distinct advantages from a supply chain and logistics perspective," he told IntelliNews. "Located at the crossroads of Europe, Asia, and the Middle East, this region boasts a strategic geographical position that provides numerous benefits for businesses seeking to optimise their supply chain operations." 

However, Sinkiewicz cautioned that tighter financing and geopolitical uncertainty were constraining investment, with occupiers and developers continuing to favour capital cities where modern warehouse stock was concentrated. "Current economic headwinds are not particularly favourable for investment. Financing conditions are tightening, while there is an uncertain geopolitical situation in the vicinity," she said. "Investment activity is limited, even in comparison with 2022 ... investors will be taking a very cautious decisions until the soaring inflation and financial instability ceases." 

Online retailers are already expanding their distribution networks further south. LPP's Bucharest centre serves six markets, including Greece, Serbia and Bosnia and Herzegovina, while Turkey's Trendyol selected Romania for a regional logistics hub in 2024. Whether robotics spreads at the same pace across the Balkans will depend largely on whether order volumes in smaller markets can justify the investment.

Software rather than humanoids

LPP's next major project is a fourth fulfilment centre in Poland, scheduled to open in 2027 with more than 1,000 robots, making it the largest in its network. It will hold more than 8mn items and dispatch over 400,000 garments and accessories a day, Sołtys said. The group is also developing a logistics hub in Kazakhstan to serve Central Asia.

Rohlik is focusing increasingly on software, aiming to develop fulfilment centres requiring minimal specialist management, with operations monitored through real-time digital twins from a central location, according to the Cognition case study. "The end game should be that a business stakeholder - a manager in finance, operations, supply chain - will be able to implement changes themselves," said Dalibor Pátek, Rohlik's product lead for warehouse automation.

For now, the region's leading logistics operators are concentrating on established technologies that move goods more efficiently and coordinate increasingly complex distribution networks, while humanoid robots and automated unloading systems remain on hold until their economics improve.

"For us, the priority is not to get carried away by market hype, but to identify the areas where technology genuinely supports the business," Sołtys said.

A small robotic frog developed at Aarhus University can swim using six artificial muscles activated by light. Behind the achievement is a systematic approach that could help researchers develop muscles for the next generation of soft robots.

It has no motor, batteries or wires. Yet a small frog created using a 3D printer by PhD student Cecilie Ryberg from the Department of Chemistry at Aarhus University can swim across the water’s surface.

It is not particularly fast. In laboratory experiments, it travelled eight centimetres in almost two minutes. But what makes the frog interesting is how it moves.

It uses six artificial muscles that work together to move its legs, pushing water backwards.

The muscles are made from materials called liquid crystal elastomers, that contracts when heated and return to their original shape as they cool.  The researchers added a molecule that absorbs near-infrared light and converts it into heat, allowing them to activate the muscles with a lamp.

"Getting the six muscles to work together was a major challenge. If they don't contract in a coordinated way, the frog won't swim forwards. It may simply spin around," explains Brigitte Städler, Professor at the Department of Chemistry at Aarhus University, who led the research project.

Artificial muscles from a piping bag

Other researchers have already developed soft robots capable of moving without wires. The scientific advance in the Aarhus University study lies in systematically examining how changing the chemistry of the liquid crystal elastomers influences their suitability for 3D printing and their response to heating, and how these properties translate into robotic movement.

"In a conventional 3D printer, you typically melt a solid plastic filament. Our material is more like very thick syrup or icing that you squeeze through a piping bag when decorating a cake. We simply use a printer to place the material precisely where we want it," explains Cecilie Ryberg.

Whale and frog trials

Developing artificial muscles suitable for 3D printing requires more than finding materials that can contract. They must also have the right consistency.

Cecilie Ryberg therefore systematically investigated how different molecular ingredients and chain lengths affect both the printing properties of the inks and the movements of the finished muscles.

The results provide other researchers with clearer guidance when choosing materials for artificial muscles, potentially reducing the amount of trial and error involved.

To demonstrate their approach, Cecilie Ryberg created two swimming robots. One resembles a whale, propelled by a single muscle that makes its tail undulate. The other is the frog, whose six muscles work together to produce forward movement.

Both the whale and the frog have bodies made from soft silicone, which the researchers 3D-printed together with the artificial muscles. They also developed a chemical method to bond the two materials together.

This is important because even the best artificial muscle is of little use if its movement cannot be transferred to the rest of the body.

From the laboratory to the playroom?

The researchers envisage that soft robots of this kind could eventually be used for applications such as environmental monitoring and search-and-rescue operations, potentially reaching places that conventional rigid robots struggle to access.

However, their current designs still require an external light source and cannot yet navigate independently around obstacles.

And if the technology eventually finds its way out of the laboratory, its first application may be considerably less ambitious than rescue missions.

"I could easily imagine these robots being used as toys before we see them on rescue missions. I think people would have fun playing with a frog like this using a suitable light source," says Cecilie Ryberg.

Researchers discover rare star system that emits radio signals every eight minutes

Scientists at the Curtin University node at the International Centre for Radio Astronomy Research (ICRAR) have linked mysterious radio pulses to an unusual pairing of stars — a dead star that spins every eight minutes and a star similar to our own Sun.

The newly discovered system, known as GPM J071507−114153, consists of two stars orbiting each other: a white dwarf — the dense core left behind when a star dies — and a G-type star similar to our own Sun.

It is the first time radio pulses have been detected from a white dwarf orbiting a Sun-like star. Typically, such pulses are observed in systems with smaller and cooler red dwarf stars, meaning the discovery breaks new ground.

These types of stellar pairs belong to a broader class of objects known as long-period transients (LPTs), producing radio signals that switch on and off over intervals ranging from minutes to hours. Around a dozen have been detected since the first was discovered by the same ICRAR team in 2021, and astronomers are still working to understand them.

While several previously discovered LPT systems contain a white dwarf and another star, it has remained unclear which of the two stars was generating the radio pulses.

“This is the first time the pulses are clear enough to see the white dwarf moving in its orbit around its companion, so we know that the pulsations are coming from a region close to the white dwarf, or possibly even from the white dwarf itself,” said lead author and commissioning scientist with the Square Kilometre Array Observatory, Dr Sam McSweeney, who made this discovery while working as a researcher at the Curtin University node of ICRAR.  The team processed more than 100 hours of radio data at the Pawsey Supercomputing Research Centre to validate and understand the white dwarf motion.

Associate Professor Natasha Hurley-Walker, co-author on the paper, said that the pulses emitted by the white dwarf allowed the team to detect stellar flares on the Sun-like star, similar to those that create aurorae here on Earth.

“As a bonus, we also saw the white dwarf moving behind a region with a strong magnetic field, most likely a ‘stellar prominence’, which is a large loop of plasma erupting from a star’s surface.”

“It’s amazing that by using radio wavelengths we can detect the storms on a star over 5000 light-years away.”

ICRAR researchers have been at the forefront of discovering these rare systems.

“We detected this system in a large survey using the MWA (Murchison Widefield Array) to scan the entire Milky Way visible from Australia. We then used the MeerKAT radio telescope in South Africa to determine its precise position,” said Associate Professor Hurley-Walker.

After the LPT was located using the radio telescopes, the W.M. Keck Observatory on Maunakea, Hawaiʻi Island, confirmed its association with a G-type star through optical observations.

Both the MWA, led by Curtin University at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-Astronomy Observatory on Wajarri Yamaji Country in Western Australia, and MeerKAT, built and operated by the South African Radio Astronomy Observatory in the country’s North Cape province, serve as precursors for the SKA telescopes, SKA-Low in Australia and the SKA-Mid in South Africa, respectively.

Dr McSweeney said, “If we are already making such discoveries with precursor telescopes, just imagine how many more star systems we will be able to find, and what a beautifully detailed view of their signals we will have, once the SKAO telescopes are completely built."

This study, ‘A long-period transient with a Sun-like companion’, was published overnight in Nature Astronomy.



The unusual system consists of a small and highly energetic white dwarf pulsar, orbiting a much larger star similar to our Sun.

Dust from the Kuiper Belt suggests the outer solar system contains water with heavy oxygen



Summary Author: Abigail Eisenstadt




American Association for the Advancement of Science (AAAS)





An examination of 12 interplanetary dust particles supports the longstanding but hard-to-prove theory that the Kuiper Belt is home to a reservoir of water that’s rich in “heavy” oxygen. Scientists have suspected that ice in the outer solar system contains heavy oxygen – non-radioactive stable isotopes of the element. Yet, whether such a cache of heavy oxygen-enriched water truly exists has proven difficult to determine; meteorites rarely arrive with clues about this mystery. Now Lindsay Keller and colleagues have circumvented the need for meteorite samples altogether. They examined interplanetary dust particles collected from Earth’s stratosphere, observing that the dust had high densities of scars from solar energetic particles – proving that the dust came from the Edgeworth-Kuiper Belt. Further analyses showed that dust particles were mainly made of hydrated minerals. Using models, Keller et al. investigated how these minerals could have formed, linking their existence to reactions with carbon dioxide and ice at low temperatures. The isotopic compositions of the minerals indicated that the water present in these reactions was made with one of two heavy oxygen isotopes, rather than normal oxygen. The evidence, the authors write, provides “compelling evidence for the presence of a major heavy water reservoir beyond the orbits of the gas giant planets that was largely isolated from inner solar system materials.”
