Emergence of quadruped walk by a combination of reflexes

Several behaviors of living things seem to be conse-quences of combinations of simple reflexes. By this hypothe-sis, emergence of walk of a quadruped robot is demonstrated by a combination of two reflexes in this paper. One reflex is to move its body according to movement of a target object which the robot gaze at, a vision-cued swaying reflex. The other is a gait reflex, a gait of a free leg so as not to make the robot fall down. As a consequence of these reflexes, the quadruped robot can walk according to the movement of the target object. 1
