Abstract: A system is provided for controling a robot operating in association with a rotary table, including a robot, a rotary table, and a control circuit.

Abstract: Synchronous operation of a multi-joint robot and a rotating table is facilitated by the provision of a multi-joint robot controller. The robot controller detects the position of an arm of the multi-joint robot relative to a coordinate system assigned to the multijoint robot and the position of a specific point on the rotating table relative to the same coordinate system. The spatial relationship of the table relative to the multi-joint robot is calculated based on the coordinates of a plurality of positions of the specific point on the rotating table.

Abstract: The present invention provides a rotation detection apparatus of a rotational axis connected to an output axis system of a reduction gear to count the rotation of a rotational axis driven rotationally, including a reduction gear, with an integer reduction ratio, whose rotational axis of a driving source is connected to an input axis. The apparatus provides a position signal once every rotation of the output axis, and a rotation angle signal in response to the rotation angle of said input axis is output to correlate said output position signal with one of said rotation angle signals to count the rotation of the rotational axis by these position and rotation angle signals. An accurate rotation can be detected even at one-way high-speed rotation.

Abstract: A tracking robot apparatus has a robot for performing a predetermined operation, a movable device for moving an object of interest, a signal input device for designating operations of the robot and the movable device, an operation device for calculating an operation instruction value of the movable device in response to an input signal from the signal input device, a controller for driving the movable device in accordance with the calculated operation instruction value, an operation device for calculating a position/posture instruction value to keep relative position and posture of the robot and the movable device unchanged upon operation of the movable device, and a controller for driving a robot in accordance with the calculated position/posture instruction value. The movable device is operated in response to the signal from the signal input device, and at the same time the robot is operated such that the relative position and posture of the robot and the movable device are kept unchanged.
