ROBOT DEVICE AND ROBOT CONTROL METHOD, RECORDING MEDIUM AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To enable a robot to act so as not to make a user feel bored. SOLUTION: An action control unit 72 calculates the action value, and determines an action (a) to be performed based on the value. When the action control unit 72 performs the action (a), a reward (r) is given by an environment user 111. The action control unit 72 updates the action value based on the reward (r) acquired from the environment user 111 and the preset learning ratio. The action control unit 72 changes the learning ratio based on input information. The present invention is applicable to an enhancement learning system of the robot. COPYRIGHT: (C)2004,JPO
