In a sewing operation robot (1), a simple harmonic motion device (2) is mounted on a wrist portion (12) thereof, and a sewing machine (5) is fixed on a sliding portion (3) of the simple harmonic motion device (2) to position the sewing machine (5) arbitrarily in a three-dimensional space and to operate the sewing machine (5) in an inching mode. A counter weight having the same weight as that of the sewing machine (5) is provided on the simple harmonic motion device (2) to prevent vibrations from occurring. Since the sewing machine is operated in the inching mode without inching the entire sewing operation robot, even a robot of low rigidity can perform sewing operations without causing friction between the sewing machine and the cloth and, further, a compact lightweight sewing operation robot can be provided.
A sewing operation robot wherein a sewing machine for performing sewing operations is fixed on a wrist portion of said robot, said robot including means for controlling the position and attitude of said wrist portion, and comprising a simple harmonic motion device for putting said sewing machine in a simple harmonic motion, said simple harmonic motion device being provided between said wrist portion and said sewing machine.
