For the automatic patrolling and protection of important facilities by General Dynamics, since the 1990s, the MDARS (Mobile Detection Assessment Response Systems) Unmanned Ground Vehicle (UGV) weighing 1.42 tons has been developed.

By 2008, 6 prototypes had been produced, and after their tests the company began serial production. In 2010, MDARS robots were first used to guard warehouses at the Hawthorne military base in Nevada.

It was equipped with automatic weapon station. In a purely patrol version, these vehicles were also purchased by the National Nuclear Security Administration (NNSA) in 2012. They were designed specifically to protect the nuclear test site in Nevada, occupying a huge area of ​​2200 square kilometers.

The MDARS robot is a 4x4 all-wheel drive chassis with dimensions of 2.49x1.59x1.17 m with the possibility of carrying a payload of up to 136 kg, which includes all-night surveillance cameras and other reconnaissance equipment located on a platform of circular rotation, or combat or non-lethal weapons. The movement of the UGV is powered by a diesel engine, which allows it to move with a maximum speed of 35 km/h, with one refueling lasting 16 hours of continuous movement. The electronics are powered by a generator.

MDARS is able to autonomously move on predetermined routes, skirting the obstacles detected by the airborne sensors, and can monitor access to the protected area, and after detecting the fact of perimeter damage, immediately notifies the operator who, together with the control point, can be up to 10 km. In the armed version, MDARS is capable of directing weapons, but permission to open fire is given only by the operator.
