A METHOD FOR CALIBRATING A ROBOT

摘要

PURPOSE: A robot calibration method is provided to maintain the uniform quality of products by gradually reflecting the state change of a robot in the calibration. CONSTITUTION: A robot calibration method is as follows. The measurement points of a measuring jig is selected on a pause period between a first and a second process. The location of the selected metering point is measured at by using the sensor of robot. One or more calibration data including the location information of the metering point is collected(S120). Calibration data is collected before the first process. Calibration data comprises the location information of one or more metering points measured by the sensor. The N number of calibration data is updated using the calibration data in a first data acquisition step. The calibration data of N robot is updated in the first rest period(S160).
