    摘要: A method and an apparatus for grasping surface mounted devices such as an IC or the like by the hand of the robot and automatically and accurately loading them onto the contact pattern of a printed circuit board by means of an image processor are disclosed. According to this method, a measurement line is provided onto each image pattern of the pin array of the surface mounted device and the array of the contact pattern of the board, so that it may intersect at right angles with the direction of the pattern, and each position of the pin array and the array of the contact pattern is sought from the variation of the brightness on that line. In accordance with the result thus obtained, displacement of the position and that of the rotation over the entire surfaced part and the contact pattern are sought and the operation of the robot is controlled in accordance with that information.

    摘要: A system for controlling an industrial robot, which is simplified in operation and capable of direct-teaching safely all the time. The system is provided with means (131 and 132) for monitoring a magnitude of an external force applied to the forward end of a hand during direct teaching, so that the motion of the robot can be forcibly restricted when the external force reaches a predetermined value of thereabove. Furthermore, when the system is operated to be set in a direct teach mode, a process (136) of correcting the offset of a force sensor is performed automatically. By monitoring a force detected by the force sensor, the discrimination is made as to whether an external force to operate the robot at an abnormal speed is applied to the robot or not, and when the external force becomes higher than a reference value, a mode of prohibiting the operation of the robot by the external force (position control mode) is set, or current supplied to a servo motor is cut off to prevent the robot from going into the erroneous operation due to an erroneous control.
