Patent attributes
A gait generating device of a legged mobile robot uses virtual surfaces to approximate a plurality of surfaces to be contacted in an operating environment of a robot, and determines the provisional values of the required virtual surface translational forces to be applied from the virtual surfaces to the robot in order to implement a translational motion of a desired motion of the entire robot. Further, to implement a rotational motion of the desired motion of the entire robot, the gait generating device determines moment compensation amounts to be combined with the provisional values of the required virtual surface translational forces and then determines the desired external forces to be applied from the surfaces to be contacted to the robot and the desired external force action points on the basis of the combinations of the provisional values of the required virtual surface translational forces and the moment compensation amounts.
