Abstract
This invention relates generally to a coupling system for releasably attaching any one of a number of robotically controlled tools (robotic 'hands') to a robotically controlled extension arm. The coupling system tightly locks the hand to the robotic arm by combined air and spring pressure such that, even under heavy duty use, the hand will not unintentionally twist or move relative to the arm, yet the hand and arm may be quickly disengaged by release of locking air pressure and imposition of unlocking air pressure which enables ball means to be cammed out of locking engagement.
