Robots come with a control panel(the KCP, or KUKAControlPanel), also known as a teach pendant, that has a display and axis control buttons for A1-A6, as well an integrated 6D mouse, with which the robot can be moved in manual(teaching) mode. The pendant also allows the user to view and modify existing programs, as well as create new ones. To manually control the axes, an enabling switch (also called a dead man's switch) on the back of the pendant must be pressed halfway in for motion to be possible. The connection to the controller is a proprietary video interface and CAN bus for the safety interlock system and button operation.
