Robotic tool changers provide flexibility to robotic applications by enabling the robot to change end-effectors automatically (e.g.; grippers, vacuum cup tooling, pneumatic and electric motors, weld guns, etc.). Tool changers consist of a master plate, which is mounted to the robot arm, and a tool plate, which is mounted to the end-effector. The tool changer passes utilities such as pneumatics, electrical signals, fluids, and more from the robot arm to the end-effector.
