Abstract: A robot toolchanger system is disclosed, where an adapter unit is mounted to the end effector of a robot. The housing of the adapter unit has central opening for receiving a T-shaped member which is affixed to a common toolbase, applied to a variety of tools. The crossbar of the T-shaped member is engaged by a slide movable in the housing in reversing directions to lock and unlock the tool with respect to the robot end effector.

Abstract: A releasable tool mount is provided for protecting tools carried by a manipulator from damage by excessive forces acting upon the tools irrespective of the direction of the force. The tool mount comprises a tool mounting plate, a housing for receiving the plate, support pins peripherally disposed upon the plate, receptacle placed within the housing for receiving the support pins and preload devices for exerting forces along the long axis of the support pins to maintain their engagement with the receptacle. Relative forces between the housing and the plate, sufficient to overcome the preload force, effect dislodgment of the pins from their associated receptacles. Fluidic sensing means are provided for detecting dislodgement of any pin from its receptacle.
