1. A multi-joint robot controller (RC) for performing predetermined tasks by operating, in cooperation, a multi-joint-robot (R) and a rotary table (T), comprising:
- position detection means (C1) for detecting a position of an arm (RA) of the multi-joint robot (R) as coordinates of a robot assigned coordinate system (O-XYZ) assigned to the multijoint robot (R);
specific point detection means (C2) for detecting coordinates of a specific point (TA) on the rotary table (T) in the robot assigned coordinate system (O-XYZ) at three or more different positions occupied by said specific point, said specific point occupying different positions by virtue of rotation of said rotary table, said coordinates being detected by the position detection means (C1); and
table attitude calculation means (C3) for calculating a center of rotation and an attitude of rotation of the rotary table (T) in the robot assigned coordinate system (O-XYZ) from said coordinates.

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.
