Abstract
In a method for changing the relative orientation between a workpiece held or clamped by a robot and an arbitrary working point, without changing a determined position, the working point is defined in a reference coordinate system of the robot. In a teaching operation, the workpiece is held or clamped by the robot with respect to the working point. The workpiece is then rotated about the working point so that the workpiece can assume a desired relative orientation with respect to the working point.
Claims1
A robot control method comprising defining an arbitrary working point, in a reference coordinate system of a robot;
- performing a teaching operation using said working point as a temporary end effector from a robot control point of a workpiece held or clamped by said robot with respect to said working point;
- and rotating said workpiece about said working point, to change the orientation of said robot to a desired relative orientation with respect to said working point.
