摘要:
The stability of attitude of a robot can be recovered by an ambulation control apparatus and an ambulation control method if it is lost in the course of a gesture for which the upper limbs take a major role. The apparatus and the method obtain the pattern of movement of the entire body for walking by deriving the pattern of movement of the loins from an arbitrarily selected pattern of movement of the feet, the trajectory of the ZMP, the pattern of movement of the trunk and that of the upper limbs. Therefore, a robot can determine the gait of the lower limbs so as to realize a stable walk regardless if the robot is standing upright or walking. Particularly, if the robot is made to gesture, using the upper body half including the upper limbs and the trunk while standing upright, it can determine the gait of the lower limbs so as to make a stable walk in response to such a gait of the upper body half.

A robot to operate accurately while canceling an affect of pitch-axis, roll-axis, and yaw-axis moments, these moments being applied on the robot body during a leg-moving operation such as walking. First, by calculating a pitch-axis moment and/or a roll-axis moment generated on the robot body at a preset ZMP by set motions of upper limbs, a trunk, and lower limbs, motions of the lower limbs and the trunk for canceling the pitch-axis moment and/or the roll-axis moment are obtained. Then, by calculating a yaw-axis moment generated on the robot body lying at the preset ZMP by the calculated motions of the lower limbs and the trunk, a motion of the upper limbs for canceling the yaw-axis moment is obtained.

A predetermined action sequence is generated by using basic motion units which include time-sequential motion of each joint and compound motion units in which basic motion units are combined. Motion natterns of a robot including walking are classified into motion units, each motion unit servins as a unit of motion, and one or more motion units are combined to generate various complex motions. Dynamic motion units are defined on the basis of basic dynamic attitudes, and a desired action sequence can be generated by using the dynamic motion units. This is a basic control method necessary for a robot to autonomously perform a continuous motion, a series of continuous motions, or motions which are chanaed in real-time by commands.

A robot operates accurately while canceling an affect of pitch-axis, rollaxis, and yaw-axis moments, these moments being applied on the robot body during a leg-moving operation such as walking. By calculating a pitch-axis moment and/or a roll-axis moment generated on the robot body at a preset ZMP by set motions of upper limbs, a trunk, and lower limbs, motions of the lower limbs and the trunk for canceling the pitch-axis moment and/or the roll-axis moment: are obtained. Then, by calculating a yaw-axis moment generated on the robot body lying at the preset ZMP by the calculated motions of the lower limbs and the trunk, a motion of the upper limbs for canceling the yaw-axis moment is obtained.

A legged mobile robot is adaptively controlled in its attitude against variable external forces to continue the operation without inversion. When the legged mobile robot kicks an object having a certain mass, such as a ball, the robot is to be prevented from being fallen down by the reactive force from the object. Even if the mass or the repulsion coefficient of the object kicked is unknown, the operation of kicking the object at a sufficiently low speed is carried out at the outset to predict the reactive force produced on actual kicking in order to predict the reactive force produced on actual kicking. The result is that the stability in attitude can be maintained on kicking at an arbitrary speed. The legged mobile robot is able to take part as one of the players in athletic games, such as soccer games, in which each player performs his or her role as the or she is subjected to an external force.
