ARCV MULE

ARCV MULE: Technical Dossier and Legal Analysis

The ARCV MULE is a four-legged unmanned ground vehicle sold by AeroArc, a subsidiary of the New Delhi group Arc Ventures (ARCV). MULE stands for Multi-Utility Legged Equipment. The Indian Army has taken delivery of a fleet of 100 for perimeter security, hazardous material handling, bomb disposal and intelligence gathering, and the manufacturer lists weapons among the payloads it can carry. The most important fact about it is its origin. Indian reporting describes it as a licensed production version of the Ghost Robotics Vision 60, and the technical data supports that description closely. I have added it to this database because it shows how armed legged robots spread by licence and how procurement can outrun doctrine, law and public debate.

• The ARCV MULE in this entry is an Indian quadruped robot weighing 51 kg. In the AeroArc context, ARCV refers to the parent company’s name, Arc Ventures, and I have found nothing that expands it further.

Basic Weapon Facts

I. Background

II. General Specifications

The identity of the numbers is the evidence for the licensing relationship. AeroArc lists an assembly and disassembly time of 15 minutes, the same figure that appears in my Vision 60 entry, and the compute module, ingress rating, weight and speed also match. I regard this as strong circumstantial support for the reported licence and as a reason to treat Ghost Robotics’ documentation as a guide to this system. The Indian build may differ in software, communications and weapon integration, and none of those differences is public. aeroarc

History and operational record

Unveiling, September 2023. The Army showed the MULE at the North Tech Symposium in Jammu. It carries thermal cameras and radars, can run pre-programmed autonomous navigation missions, and can mount small arms to fire at enemy positions from a safe distance. An engineer quoted at the event described the use case in plain terms. The operator locates where an adversary is inside a room, and the firing platform is then available to engage. thedefensepost

Procurement, September 2023. ThePrint reported that the Army signed a contract that month for emergency procurement of 100 units. The emergency route allows contracts up to ₹300 crore, and the numbers were deliberately small pending performance. theprint, indiandefensenews

Induction, 2024. The first 25 arrived in June 2024. The Army then laid down standard operating procedures, and the robots were intended to be sent in ahead of troops if a terrorist hideout had to be raided. The MULE appeared at the Army Day Parade in Pune the following January. tribuneindia, millenniumpost

Corporate lineage. AeroArc’s founder Arjun Aggarwal described the MULE as a co-development with Ghost Robotics. The same company supplies Trinetra surveillance drones that are, in its words, Indianised at a Coimbatore facility from a design originated by the US firm Skydio. The pattern is consistent. AeroArc takes proven American designs, localises production and sells them to the Indian military under the banner of self-reliance. theprint, theprint

Weapons integration. AeroArc’s catalogue lists small arms, electro-optical and thermal sensors, loitering munitions, a robotic arm and chemical and radiation detection as available payloads, and separately lists the RS-1, a stabilised remote weapon station carrying a small calibre rifle. The product menu also names a “Precision Auto-Targeting System”. I could not establish whether that product is related to the MULE or what it does, and I mark it as an open question for the manufacturer. No public record shows any armed MULE in combat. aeroarcaeroarc

Autonomy: a forensic analysis

Sensors. Thermal cameras and radars are reported for the Army configuration. The catalogue adds electro-optical payloads and chemical and radiation sensors. Together they make a surveillance and detection platform that can also serve as a targeting sensor. thedefensepost

Algorithms. The compute module is an NVIDIA Xavier, a processor class designed for onboard machine vision. For the underlying Ghost Robotics platform, the manufacturer says its Mission Control software supports autonomous navigation in GPS-enabled and GPS-denied environments using LiDAR mapping. Whether the Indian build uses the same software stack is Unknown. The Army describes pre-fed missions that enable autonomous navigation. One secondary source says the MULE operates autonomously or by remote control, and I give that little weight, because it does not distinguish navigation from engagement. aeroarc, thedefensepost

Human intervention in the kill chain. The reporting describes operator-controlled weapon use. Defence sources say the robots can engage without putting a human life at risk, which describes the safety of the operator and says nothing about who decides to fire. I found no evidence of autonomous target selection or engagement. The comparable Ghost Robotics case is instructive. The US Marine Corps Special Operations Command tested a Ghost robot with a remote weapon system that can detect and track people, drones and vehicles but cannot shoot autonomously, because a human operator makes the firing decision. That arrangement is the plausible design for the Indian build, and it is an assumption I cannot confirm. theprint, warriormaven

Classification. On the public record the ARCV MULE is a remotely operated platform with autonomous mobility and sensing, and it is not a lethal autonomous weapon system as the CCW process uses the term. I list it because the capability gap between this system and one that is autonomous is small and entirely a matter of software and policy. I discuss that threshold in my Vision 60 entry, in the Unitree B2 entry, and on my stance page. For comparison across the region see Norinco Sharp Claw and Hanwha Arion-SMET.

Legal analysis

Weapons review

Article 36 of Additional Protocol I requires states parties to review new weapons for legality. India is not a party to Additional Protocol I, as far as I know, though the principle of legal review is widely treated as good practice and the underlying rules of distinction and proportionality bind India as customary law. I know of no public statement that the Indian Army reviewed an armed MULE configuration. The modular problem I described for the Vision 60 applies in full. The platform, the weapon station and the rules of engagement come from different hands, and no public document shows who assessed the whole.

Which legal regime governs the likely use

This is the question I find most important here. Reporting says the MULE is meant to go in ahead of troops in raids on hideouts, which describes counter terrorism operations on Indian territory. India has generally not accepted that situations such as Jammu and Kashmir amount to armed conflict, so the governing framework would be law enforcement and human rights law, not the conduct of hostilities rules. India is a party to the ICCPR, and Article 6 protects the right to life. The UN Basic Principles on the Use of Force and Firearms by Law Enforcement Officials allow intentionally lethal force only where strictly unavoidable to protect life. A robot that identifies a person in a room through a thermal camera and then fires on operator command sits uneasily with that standard, because the robot’s selling point is that it removes risk to the operator, and the legal test asks whether the person in the room posed an imminent threat to life. A machine that sees through walls and shoots without warning is built for the opposite assumption.

If an armed conflict framework applies, for instance on a front with Pakistan or China, then distinction, proportionality and precaution under Articles 48, 51 and 57 apply, together with Article 41’s protection of anyone hors de combat.

Indian law and accountability

The Indian domestic framework matters more than usual because the system is for home use. The Armed Forces (Special Powers) Act 1958 gives wide powers in notified areas, and Indian courts have drawn limits around it. In Naga People’s Movement of Human Rights v. Union of India (1997) the Supreme Court upheld the Act’s constitutionality while requiring that powers be exercised with care. In Extra Judicial Execution Victim Families Association v. Union of India (2016) it held that the Act does not give absolute immunity and that allegations of excessive force are open to inquiry. Article 21 of the Constitution protects life and personal liberty. Those cases concern soldiers, and none has addressed a robot firing at an operator’s command. The practical issue is evidentiary. Accountability depends on knowing who decided to fire, on what information, and from what record, and a remote weapon platform should generate that record by design. Whether the Army’s SOPs require it is Unknown. I flag all three case citations from my own knowledge for checking.

Arms transfer chain

A US-designed system, licensed for production in India, from a firm majority-owned in South Korea, creates a three-jurisdiction supply chain. US export control law governs the licence. Articles 6 and 7 of the Arms Trade Treaty require exporting states to assess the risk of serious violations, and South Korea is a party, the United States a signatory that has not ratified, and India a non-signatory. I have found nothing public about the export licence or end use conditions, so I treat the question of which state is responsible for a misuse as unresolved.

International relations implications

Mirror image arms racing in Asia. Chinese state media have shown armed Unitree robots, and India now fields a Ghost-derived robot that can carry small arms. My Unitree B2 entry sets out the Chinese side. Both countries face each other across the Line of Actual Control, where the 2020 Galwan clash cost lives and where pack animals have long carried loads at altitude. Armed or unarmed, a robot that can follow soldiers up a mountain slope has an obvious logistical purpose, and I do not want to dismiss it. The same robot also gives each side a reason to match the other’s capability, and that is how an arms race starts.

India as a swing state at the CCW. Carnegie India reports that India views calls for a binding instrument as premature, and notes that Russia also opposes any binding instrument and treats the GGE as the sole forum. I recall that India voted against UN General Assembly resolution 78/241 in 2023, which passed with 152 votes in favour, and I flag that for verification. The UN Secretary-General and the ICRC have called for a treaty by 2026. On 5 September 2026 the CCW Group of Governmental Experts reached consensus among 128 states on a document addressing lethal autonomous weapons systems, though critics argue major military powers weakened it. France says the text clarifies human control and judgment and that the Review Conference must decide next steps. The ICRC urges states to use the conference to launch negotiations on a new protocol. India’s position will matter, partly because it is both a large Global South state and a growing builder of these systems. A state that is arming its own forces with armed ground robots has an interest in the rules, and its stance should be judged against its procurement. • Research

Technology dependence and sovereignty. India calls its defence industrial push self-reliance, yet this system and AeroArc’s drones are localised foreign designs. The Trinetra drone is an Indianised version of a US design, and the MULE is reportedly a licensed Ghost Robotics platform. Dependence on a foreign licensor means that an export licence decision in Washington or a change of control in Seoul could affect a deployed Indian fleet. It also complicates accountability, because responsibility for design, software and weapon integration spreads across three countries. theprint

Procurement speed as a governance problem. The Army wrote the operating procedures after the first units arrived. Emergency procurement exists for good reasons, and it also bypasses the slower scrutiny that a new weapon category might attract. A capability that enters service this way tends to become permanent by default. I would like to see a published account of the legal review, the rules for armed use and the audit trail, for this system and any other. tribuneindia

The Global South as manufacturer. Most debate about autonomous weapons assumes a few advanced states build them and the rest receive them or suffer them. India, Turkey, South Korea and others are changing that picture. A broader set of producers makes consensus harder and makes export controls more important. It also gives states with real experience of conflict a stronger claim to shape the rules.

My assessment

I can see the value of a robot that carries a soldier’s load up a mountain, finds a bomb or goes into a contaminated room, and I take the Army’s stated purposes seriously. The weapon mount is where I become cautious. What troubles me about the ARCV MULE is how quietly it arrived. It came through an emergency route, under a licence whose terms are not public, from a platform whose maker has defended arming its robots, with procedures written after delivery and no public statement about legal review. The name does not help. A mule is a pack animal, familiar and uncontroversial, and the word makes the machine sound like the thing it replaces.

I hold the same position here that I hold on my stance page. Meaningful human control has to be designed in, written into law and attached to identifiable people, and it cannot rest on assurances from a manufacturer or a defence source. I would ask India to publish its weapons review process, state which legal framework governs domestic use of armed robots, and take that position to Geneva in November. I explain how I came to this work in my story, and I set out the wider risks on my AI safety page. The policy context is tracked in my research and the AI Policy Tracker.
