ROBOT FOR SEWING WORK.

A robot for sewing work in which a simple harmonic oscillation device is fixed to the wrist part of the robot and a sewing machine is fixed to the sliding part of said simple harmonic oscillation device and positioned optionally in the three dimensional space so as to perform inching. A counterweight equal to the sewing machine in mass is provided to the simple harmonic oscillation device for preventing vibration of the sewing machine. The sewing machine is adapted to perform inching without causing inching of the whole of the robot, whereby even when a robot low in rigidity is used, sewing can be performed without generation of friction between the sewing machine and the fabric to be sewn and a robot for sewing work small in size and light in weight can be provided.
