  • Safe and arm system for a robot
    Patent number: 7905177
    Abstract: A safe and arm system includes an operator control subsystem including a first arm switch, a second arm switch, and a fire switch. A fire control subsystem is responsive to the operator control subsystem and includes at least a pair of terminals for connection to a munition. The terminals are initially shorted together and without a ground. A power supply control circuit is configured to supply power to the terminals. A ground supply circuit is configured to ground one said terminal. A terminal shorting circuit is configured to remove the short across the pair of terminals. The power supply control circuit, the ground supply circuit, and the terminal shorting circuit are configured to ground one terminal, remove the short across the pair of terminals, and to supply power to the terminals only if the first and second arm switches and the fire switch are all activated in a predetermined sequence.
