In order to complete a flexible automated assembly system, a robot called parts supplying robot has been developed, with which one assembly line can be built compactly and parts supplying from three dimensionally stacked parts-feeding equipments can be realized easily. In this report, fundamental structure of the parts supplying robot is given. The method to select a shortest PTP path is discussed and the effect for high-speed motion of robot is shown. Its PTP motion is evaluated, and improved by using a balanced arm structure and an input compensation. Finally simulation results are shown.
