THREE-AXIS HOME POSITION CALIBRATION METHOD FOR SIX-AXIS ROBOT, CONTROLLER FOR SIX-AXIS ROBOT, AXIAL HOME POSITION CALIBRATION METHOD FOR ARTICULATED ROBOT, AND CONTROLLER FOR ARTICULATED ROBOT
THREE-AXIS HOME POSITION CALIBRATION METHOD FOR SIX-AXIS ROBOT, CONTROLLER FOR SIX-AXIS ROBOT, AXIAL HOME POSITION CALIBRATION METHOD FOR ARTICULATED ROBOT, AND CONTROLLER FOR ARTICULATED ROBOT
PROBLEM TO BE SOLVED: To provide an axial home position calibration method for properly calibrating a home position of an axis in an articulated robot without requiring mounting of an exclusive tool and without installation of a large-sized detection device.;SOLUTION: In a controller 3 for the robot 2 constituted to have a 2-axis rotary shaft, a 3-axis rotary shaft, and a 5-axis rotary shaft in parallel to prevent them from crossing each other, each axis is moved to return a coordinate of a measuring point from the state where the robot 2 is held at measuring attitude, a coordinate of the measuring point before moving each axis is compared with a coordinate of the measuring point after moving each axis by utilizing the characteristic where the coordinate of the measuring point before moving each axis does not agree with the coordinate of the measuring point after moving each axis if a home position of the 3-axis is deviated, and an angle of error is led out to calibrate the home position of the 3-axis.;COPYRIGHT: (C)2010,JPO&INPIT
