ROBOT CALIBRATION METHOD

摘要

A robot calibration method is provided to detect a precise relative position of a tool center point based on image information measured from a laser vision sensor. A robot calibration method comprises the steps of detecting a specific teach point of a teach pendant by using a detection unit(S100), calculating a measurement value of the specific teach point(S200), calculating an error value by comparing the calculated measurement value with a value calculated through an equation(S300), obtaining error components based on the calculated error value(S400), and obtaining a correction equation by applying the error components to the calculated value(S500).
