The T-1 Battlefield Robot, also known as T-1 Ground Assault Vehicle, is a fully autonomous Ground Offensive System and the first Terminator class robot and a Hunter-Killer Tank prototype to be produced by Cyber Research Systems. Designed for extreme combat, the Series 1 was built to clear battlefields of enemy troops with its powerful weaponry. The design of the HK-Tank was an evolution of the T-1, while the concept of T-835 may originate from the T-1.
