  • Control system of multi-joint arm robot apparatus
    Patent number: 5307447
    Abstract: A multi-joint arm robot apparatus comprises a multi-joint arm having a plurality of unit arms coupled in tandem with each other through joints, and a movable support for supporting the proximal portion of the multi-joint arm. The multi-joint arm robot apparatus has motors for controlling joint angles of the joints and a motor for moving the movable support. These motors are driven by a control system. The control system controls the motors to obtain proper joint angles, in such a way that the joints of the multi-joint arm are put into a given path when the movable support is moved a given unit distance.

  • Multi-joint arm robot apparatus
    Patent number: 4631689
    Abstract: A multi-joint arm robot apparatus which includes a multi-joint arm in which a plurality of unit arms are connected in tandem through joints, a driver mechanism arranged in the multi-joint arm to drive each of the joints, a state detecting mechanism arranged in the multi-joint arm to detect the state of each of the joints, and a signal processing mechanism for driving the joint driver mechanism to move the multi-joint arm on a proper path responsive to the state detecting mechanism. For the purpose of reducing the number of signal transmission lines in the multi-joint arm, the signal processing mechanism transmits time-division control signals to the state detecting mechanism in each of the joints through a common control signal line arranged in the multi-joint arm, and the state detecting mechanism transmits state detecting signals to the signal processing mechanism in a time division manner through a data transmission line arranged in the multi-joint arm in response to the time-division control signals.
