Abstract
An industrial robot is used to assemble a part to a predetermined location on a randomly moving workpiece. The workpiece may be an automobile on an assembly line and the part may be a wheel (a tire mounted on a rim) to be assembled on one of the wheel hubs of the automobile. The robot has mounted on it a camera, a force sensor and a gripper to grip the part. After the robot grips the part, signals from both the force sensor and vision are used by a computing device to move the robot to a position where the robot can assemble the part to the predetermined location on the workpiece. The computing device can be the robot controller or a separate device such as a PC that is connected to the controller.
