摘要: A robot profile control system is disclosed which permits a force control robot (70) to perform a profiling operation on a surface of a work object having curved surfaces of unknown contours while resetting a profile coordinate system for the profile operation on the basis of force acting between the end of the robot and the work object which is detected by a force detecting section (11). The system comprises a normal vector calculating section (13a) responsive to the force detecting section for calculating a normal vector at a point of contact between the robot end and the work object, a vector in direction of movement calculating section (14a) responsive to outputs of the normal vector calculating section (13a) and a position detecting section (12) adapted to detect the position of the robot end and the position of an end point of the profile operation or a vector in direction of movement of the robot end which is provided from an operator for calculating a vector in direction of movement of the robot end, a control command generating section (15a) responsive to outputs of the normal vector calculating section (13a) and the vector in direction of movement calculating section (14a) for generating control commands for the robot, a force control section (19) responsive to outputs of the control command generating section (15a) and the force detecting section (11) for controlling the force of the robot, and a position control section (18) responsive to outputs of the control command generating section (15a) and the position detecting section (12) for controlling the position of the robot end. The profile coordinate system is defined by a unit vector n in the direction in which the robot end is pressed on the object which coincides with the direction of an inward normal on the surface of the object at a point of contact between the robot end and the object, a unit vector o in the direction of movement of the robot end and a third unit vector a obtained as the outer product of the two unit vectors n and o . The profile coordinate system is reset at regular intervals to continue the profiling operation.
