Abstract

A general-purpose jig is provided which includes a base, a locational holding device mounted on the base and having a tripod robot that includes three expansion actuators, and a clamp attached to the locational holding device. The position of the clamp can be changed by changing the length of each of the expansion actuators, depending upon an object to be held, according to a command from a control device. The locational holding device may further include a three-axis rotary unit located between the clamp and the tripod robot. The posture of the clamp can be kept constant by controlling the three-axis rotary unit while the clamp is being moved by the expansion actuators.
