deep mud. The vehicle is controlled using the Marionette system which is also used on Wheelbarrow EOD robots. The Warrior A new model of the PackBot was also produced, known as the Warrior. It is over five times the size of a PackBot, can travel at speeds of up to 15 mph, and is the first variation of a PackBot capable of carrying a weapon (Singer, 2009a). Like the Packbot, they play a key role in checking for explosives. They are capable of carrying 68 kilograms, and travelling at 8 MPH. The Warrior is priced at nearly 400,000 and more than 5000 units have already been delivered worldwide. TerraMax The TerraMax UVG package is designed to be integrated into any tactical wheeled vehicle, and is fully incorporated into the brakes, steering, engine and transmission. Fitted vehicles retain the ability to be driver-operated. Vehicles manufactured by Oshkosh Defense and fitted with the package have competed in the DARPA Grand Challenges of 2004 and 2005, and the DARPA Urban Challenge of 2007. The Marine Corps Warfighting Lab selected TerraMax-equipped MTVRs for the Cargo UGV project initiated in 2010, culminating in a technology concept demonstration for the Office of Naval Research in 2015. Demonstrated uses for the upgraded vehicles include unmanned route clearance (with a mine roller) and reducing personnel required for transportation convoys. THeMIS The THeMIS (Tracked Hybrid Modular Infantry System), unmanned ground vehicle (UGV), is a ground-based armed drone vehicle designed largely for military applications, and is built by Milrem Robotics in Estonia. The vehicle is intended to provide support for dismounted troops by serving as a transport platform, remote weapon station, IED detection and disposal unit etc. The vehicle’s open architecture gives it multi-missions capability. The main purpose of the THeMIS Transport is to support onbase logistics and provide last mile resupply for fighting units on the front line. It supports infantry units by reducing their physical and cognitive load, increasing stand-off distance, force protection and survivability. THeMIS Combat UGVs provide direct fire support for manoeuvre forces acting as a force multiplier. With an integrated self-stabilizing remote-controlled weapon system, they provide high precision over wide areas, day and night, increasing stand-off distance, force protection and survivability. Combat UGVs can be equipped with light or heavy machine guns, 40 mm grenade launchers, 30mm autocannons and Anti-Tank Missile Systems. THeMIS ISR UGVs have advanced multi-sensor intelligence gathering capabilities. Their main purpose is
