Novel flexible foot system of human-imitated robot

The invention discloses a flexible foot system of a human-imitated robot, mainly comprising four small foot bottom plates, a support main shaft and a micro-motor driving system. The flexible foot system is characterized in that each novel flexible foot comprises the four small foot bottom plates which can independently pitch up and down, and is connected with the support main shaft by a rotation pair and is provided with a torsional spring, so that the feet can ensure a certain starting pose and a certain starting force; a pair of spring damping fasteners are arranged below each foot bottom plate and is driven through a flexible rope by a miniature motor, and a front end grounding slide block connected with a spring is pulled to move back and forth so as to realize the adjustment of a contact position according to the concave and convex status of the ground; four designed flexible feet pitch around a Y shaft, the other four designed flexible feet move along an X shaft, the designed flexible feet totally have eight degrees of freedom, thereby ensuring the four-point contact between the feet and the concave and convex ground; and the invention successfully solves the problem that the foot bodies of the human-imitated robot and a ground environment uncertain model are not matched, and can enable the human-imitated robot to adapt to more uncertain environments.
