Compact T4 bomb disposal robots bring haptic ‘touch’ to UK forces

The UK armed forces have introduced the L3Harris T4 bomb disposal robots, described as the “world’s most capable” threat-neutralizing unmanned ground vehicles (UGVs). These medium-sized robots are being deployed with British Army and Royal Navy explosive ordnance disposal (EOD) teams across the UK, Cyprus, and Gibraltar as part of a £32 million program to acquire 50 units. The T4 robots feature advanced controls, high-definition cameras, and a haptic feedback system that allows operators to “feel” what the robot’s arm touches, enhancing precision in handling explosive threats. Compared to the larger T7 models already in service, the more compact T4s weigh about 100 kilograms, can maneuver in confined spaces, climb stairs, and fit into standard 4×4 vehicles, making them ideal for rapid emergency response. The T4 robots share a haptic interface with the T7, enabling near-human dexterity for tasks such as unzipping bags or manipulating suspicious
