Abstract
A robot controller includes at least one memory that stores a plurality of mechanism error parameters including a first mechanism error parameter and a second mechanism error parameter. At least one processor of the robot controller acquires an actual measurement position and information on a status of a robot by driving the robot with a plurality of orientations at a plurality of positions based on the second mechanism error parameter. The at least one processor calculates a third mechanism error parameter by correcting a value of the first mechanism error parameter based on the acquired actual measurement position and information on the status of the robot. The robot is controlled based on the plurality of mechanism error parameters including the second mechanism error parameter and the third mechanism error parameter.
