Abstract
A controller includes a parameter setting unit that invalidates first mechanism error parameters. The controller includes a measurement control unit that drives a robot with a plurality of orientations at a plurality of positions by using second mechanism error parameters other than the first mechanism error parameters and measures the actual measurement position of the robot by a three-dimensional measuring device. The controller includes a parameter calculation unit that calculates the first mechanism error parameter based on the actual measurement position of the robot and the rotation position of a robot drive motor. The controller includes a correction unit that changes the first mechanism error parameter invalidated by the parameter setting unit to the first mechanism error parameter calculated by the parameter calculation unit.
