Robot controller

Abstract

When a position deviation of teaching point of a robot manipulator is detected during continuous operation of a robot system, device for correcting the teaching point without stopping continuous operation of the robot system is provided, thereby presenting device for operating the robot system efficiently without having effects on productivity of the production line. Having a changeover unit for changing over modes by selecting from an input mode for entering teaching points, an operation mode for operating according to the teaching points, and an in-process correction mode for correcting the teaching points stored in the storage unit according to the data from the input unit during operation of the robot manipulator, the mode is changed over to the in process correction mode by the changeover unit, the data for correcting the teaching point is entered from the input unit, and the control unit corrects and processes according to the entered data.
