ABSTRACT:
A compliancy joint for a robot has six degrees of compliancy freedom and comprises a housing having an inner ring. A float block is movably disposed in the interior of the housing and a plurality of circumferentially arranged pneumatic cylinders on the housing apply force circumferentially to the float block. Sensors are used to detect when the float block is near its compliancy limit and a controller is operatively connected to the sensors and the cylinders for preventing the float block from reaching its compliancy limit. This joint is able to break away from the robot should the robot exceed the device's compliancy limit, preventing damage to the robot and robot end of arm tooling.
