    摘要: A numerical control system suited for application to a machine tool having an axis of rotation, such as a robot which employs a cylindrical coordinate system. For example, when the arm (3) of an industrial robot is rotated to transport a wrist (2), which is attached to the end of the arm (3), from a starting point (P.sub.1) to an end point (P.sub.2), the straight line (L.sub.n) interconnecting the starting point (P.sub.1) and the end point (P.sub.2) is divided into a plurality of intervals {Q.sub.i, Q.sub.(i+1), . . . }, positional data for each axis at each of the division points is generated, and linear interpolation for each of the intervals is performed by using the positional data for each axis to move the wrist (2) approximately along the straight line.

    摘要: The hand of a robot is moved from an instant position P.sub.1 to a first command position P.sub.2 to grip one of the workpiece W.sub.1,W.sub.2,W.sub.3 placed at the first command position and conveys the same to a second command position P.sub.3. A sensor is contacted by the workpiece when the hand takes an intermediate position Px on its way from the instant position P.sub.1 to the first command position P.sub.2, the robot control system stops the hand without delay or after travel of the hand over a predetermined distance and, after the travel of the hand over a predetermined deceleration distance, stops the hand. The hand is then moved from the stopping position to the second command position P.sub.3 neglecting the remaining stroke or movement between the stopping position and the first command position.
