Safe and arm system for a robot

Abstract

A system (10) for remotely enabling and disabling a weapon (12), includes a watchdog controller (14) adapted to receive a safe/arm command from a remote source (16) and to transmit the safe/arm command if predetermined conditions are satisfied, a safe/arm controller (20) adapted to receive the safe/arm command from the watchdog controller (14) and to transmit a control signal to enable communication between a weapon system processor (24) and the weapon (12) if a predetermined series of input signals are received in a predetermined sequence. The system also includes a switch (22) in a communication path between the weapon system processor (24) and the weapon (12). The safe/arm controller (20) closes the switch (22) and enables communication between the weapon system processor (24) and the weapon (12) only when the safe/arm controller (20) receives an arm signal and receives the predetermined series of input signals in the predetermined sequence.
