Abstract
A robot apparatus includes a robot mechanism; a sensor provided in a portion whose position is to be controlled, of the robot mechanism, for detecting a physical quantity to obtain positional information of the portion; and a robot controller having an operation control unit for controlling the operation of the robot mechanism. The robot controller includes a learning control unit for calculating a learning correction value to improve a specific operation of the robot mechanism based on the physical quantity detected, while the operation control unit makes the robot mechanism perform the specific operation, with the sensor; and a learning extension unit for obtaining the relationship between the learning correction value calculated by the learning control unit and information about the learned specific operation, and calculates another learning correction value to improve a new operation by applying the obtained relationship to information about the new operation without sensor.
