ABSTRACT:
A controller of a leg type moving robot determines an action force to be input to an object dynamic model2such that a motion state amount (object model velocity) of the object dynamic model2follows a desired motion state amount based on a moving plan of an object, and also determines a manipulated variable of the motion state amount (object model velocity) of the object dynamic model2such that the difference between an actual object position and a desired object position approximates zero, and then inputs the determined action force and manipulated variable to the object dynamic model2to sequentially determine the desired object position. Further, a desired object reaction force to a robot from the object is determined from the determined reaction force. This arrangement causes the robot to perform an operation of moving an object while securing stability of the robot by determining the desired motion of the object and the desired value of an action force between the object and the robot while minimizing the difference between a motion state of the object on the object dynamic model and an actual motion state.
