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.
