Abstract: A system for incorporation into a manually controlled vehicle to provide unmanned operational capability to the vehicle, comprises a quantity of subsystem controllers. The subsystem controllers include: a throttle controller, integratable with an existing throttle system of the vehicle; a brake controller, integratable with an existing brake system of the vehicle; and a steering controller, integratable with an existing steering system of the vehicle. An actuator control system is operably coupleable to each of the subsystem controllers, and the actuator control system is capable of enabling remote or automated control of each of the subsystem controllers. An interrupt device is operably coupled to the actuator control system, the interrupt device providing selective: i) actuation of the actuator control system to provide remote or automated control of the subsystem controllers; and ii) deactivation of the actuator control system to return the subsystem controllers to a manually controlled state.
