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.
