Abstract :
In order to keep intended distance and direction to a target object, our biped robot modifies its movements based on visual information. To detect the target direction, we stabilize gaze of the robot by 2-DOF controller, using a scheduled robot motion plan for the feedforward one and the image information for the feedback one. Then, we stabilize the robot motion with the stabilized gaze. In this control scheme, parameters of the feedforward controller is modified on-line by using an adaptive law of model reference adaptive control (MRAC).
