ROBOT SYSTEM CAPABLE OF EFFICIENTLY APPROACHING/SEPARATING FROM TARGET POINT

摘要

PURPOSE: A robot system is provided to efficiently perform the movement of a robot for approaching or separating the certain part of an end effecter from a certain part of an object. CONSTITUTION: A camera of a visibility sensor is mounted with a robot to come the end of an end effecter in sight of the camera. The end of the end effecter and a target point of an object are appointed on a monitor screen. In pressing an approach key, a difference between the end of the end effecter and the target point is calculated(S2) by detecting the target point on the screen(S1). The difference is compared with an allowable range(S3). A moving distance of the robot is calculated according to the result. Then, the robot is moved(S4). The processes are repeated until stopping the press of the approach key. In pressing a retreat key, the robot is moved to separate from the object. The robot is stopped by using a distance sensor.
