| 20110098856 | CONTROL DEVICE FOR LEGGED MOBILE ROBOT - A control device for a legged mobile robot has a first motion determiner which sequentially determines the instantaneous value of a first motion of a robot by using a first dynamic model and a second motion determiner which sequentially determines the instantaneous value of a second motion of the robot by using a second dynamic model, and sequentially determines a desired motion of the robot by combining the first motion and the second motion. A low frequency component and a high frequency component of a feedback manipulated variable having a function for bringing a posture state amount error, which indicates the degree of the deviation of an actual posture of the robot from a desired posture, close to zero are fed back to the first motion determiner and the second motion determiner, respectively. | 04-28-2011 |
| 20110098860 | CONTROL DEVICE FOR LEGGED MOBILE ROBOT - A control device for a legged mobile robot has a unit which generates the time series of a future predicted value of a model external force manipulated variable as a feedback manipulated variable for reducing the deviation of the posture of the robot. A desired motion determining unit sequentially determines the instantaneous value of a desired motion such that the motion of the robot will reach or converge to a reaching target in the future in the case where it is assumed that the time series of an additional external force defined by the time series of a future predicted value of the model external force manipulated variable is additionally applied to the robot on a dynamic model. | 04-28-2011 |
| 20110160906 | CONTROL DEVICE FOR MOBILE ROBOT - A control device for a mobile robot, in which the desired value of a motion state amount of a mobile robot includes at least the desired value of a vertical component of a first-order differential value of the translational momentum of the entire mobile robot. The desired value is determined by a state amount desired value determiner such that the observed value of the vertical position of an overall center-of-gravity point of the mobile robot is converged to a predetermined desired value according to a feedback control law. A control input determiner carries out the processing of inverse dynamics calculation, using the desired value of the motion state amount thereby to determine the desired driving force for each joint. The operation of an actuator is controlled on the basis of the determined desired driving force. | 06-30-2011 |
| 20110160907 | CONTROL DEVICE FOR ROBOT - A control device for a robot determines, as a desired driving force to be imparted to a joint, a component value corresponding to the displacement amount of each joint out of a desired generalized force vector τcmd that satisfies the relationship indicated by expression 01 given below by using basic parameter group of M, N, and Jacobian matrixes Jc and Js, a desired value ↑C of the motion acceleration of a contact portion representative element representing a motion of a contact portion of a robot | 06-30-2011 |
| 20110213494 | GAIT GENERATING DEVICE OF LEGGED MOBILE ROBOT - 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. | 09-01-2011 |
