Abstract
A robot device includes: a robot; an operation control section; a sensor configured to detect a value related to a position of a control target portion of the robot; a low-speed position information acquisition section configured to acquire low-speed position information of the control target portion; a calibration section configured to perform calibration between the sensor and the robot by using the low-speed position information and a command position; and a learning control section configured to learn a correction amount that reduces a deviation between operation described in an operation program and an actual operation of the control target portion, by using a detection value of the sensor that is acquired when the robot is operated in accordance with the operation program, the low-speed position information or the command position, and calibration data acquired through the calibration.
