THeMIS - Robot Details, Use Case and Specifications

The THeMIS is a modular Unmanned Ground Vehicle (UGV) developed by Estonian company Milrem Robotics as a multi-role robotic platform for military and defense applications. Built on a robust tracked chassis with hybrid diesel-electric propulsion and open architecture, THeMIS can be rapidly configured for logistics, reconnaissance, casualty evacuation, obstacle breaching, combat support, and ordnance disposal missions while reducing human risk in high-threat environments. Its modular design supports a wide range of weapon systems, sensors, and mission payloads from leading partners including Kongsberg, FN Herstal, Leonardo, and others, making it one of the most widely adopted UGV platforms across NATO and allied armed forces. The system has been operationally proven in demanding conflict environments and is used by 19 nations.

Use Cases

Logistics & Resupply Support:
Transports equipment, supplies, ammunition, and gear for troops, reducing physical strain and exposure to danger.
Combat Support & Firepower Extension:
Integrates remote weapon stations and weapon systems (MGs, autocannons, grenade launchers, missiles) to provide direct fire support and force protection.
Intelligence, Surveillance & Reconnaissance (ISR):
Carries sensor payloads (LiDAR, cameras) to gather battlefield information and improve situational awareness.
Explosive Ordnance Disposal (EOD):
Can be configured for mine detection, clearance, and other hazardous ordnance tasks without risking personnel.
Casualty Evacuation (CASEVAC):
Serves as an unmanned platform to extract wounded personnel from dangerous zones

Intro

The THeMIS stands for Tracked Hybrid Modular Infantry System, is Milrem Robotics’ flagship multi-role unmanned ground vehicle that blends modular payload support, robust mobility, and battlefield durability into a flexible platform for modern defense needs. Built on a tracked chassis, THeMIS uses a hybrid propulsion system combining a diesel engine with an electric drive to deliver up to 15 hours of hybrid runtime and sustained silent operations of about 1.5 hours on battery alone. Its design emphasizes open architecture, enabling rapid integration of third-party payloads, from remote weapon stations and anti-tank guided missiles to ISR sensors, robotics kits, and medical evacuation modules without significant structural changes.

Measuring approximately 2.47 m long, 2.04 m wide, and 1.17 m high, with a weight of around 1,630 kg, THeMIS stands out for its ability to operate in harsh climates and extreme terrains while supporting dismounted forces. Its tracked mobility allows it to cope with 60% grades and 30% side slopes, overcome 90 cm gaps, and maintain a ground clearance of about 60 cm, giving it excellent off-road capability. The vehicle’s line-of-sight control range can reach up to 1.5 km with encrypted 2.4 GHz MIMO Mesh communication, and its controller mesh supports AES-256 encryption and frequency hopping. THeMIS has been combat-tested and deployed in conflicts such as the Russian invasion of Ukraine and anti-insurgency operations like Barkhane, demonstrating both operational resilience and flexibility across mission profiles.

Milrem’s modular philosophy allows THeMIS to host a wide range of mission-specific extensions: from simple cargo platforms and CASEVAC capsules to remote weapon stations like Kongsberg’s PROTECTOR RS4/RS6, FN Herstal’s deFNder Medium, Leonardo’s HITROLE Light, and payloads such as the Loki counter-drone turret. This modularity, paired with optional autonomous capabilities through the Milrem Intelligent Functions Kit (MIFIK), lets THeMIS conduct advanced waypoint navigation, off-road autonomy, and obstacle avoidance, expanding its role beyond a remote asset to a semi-independent battlefield partner.
