  • Orientation-dependant robot controller
    Patent number: 4804897
    Abstract: A joystick controller includes three gravity sensing switches, the outputs of which can be used in the assignment of joystick transducer outputs in six different ways depending on controller orientation. This permits intuitive control of a robot arm in that translational motions can always be effected by moving the joystick in the direction the arm is to move. Thus, a controller which is economical, reliable and intuitive multiplies the functions available from what is basically a two or three dimensional controller.
