Abstract:
Provided is a robot device comprising: a robot arm which has a specific part, and moves the specific part to a plurality of positions on a first coordinate system that is three-dimensional; a measurement device that measures, on a second coordinate system that is three-dimensional, each position of the specific part at the plurality of positions; a conversion unit that obtains a conversion relationship including a non-linear component between the position of the specific part on the first coordinate system and the position of the specific part on the second coordinate system; and a control unit that converts a position designated on the second coordinate system into a position on the first coordinate system using the conversion relationship, and controls the robot arm on the basis of the resultant position. It is possible to calibrate the position of the robot arm with high accuracy and easily.
