Self-reinforcement anti-skid bionic foot with adjustable stress position

The invention relates to a self-reinforcement anti-skid bionic foot with an adjustable stress position; the self-reinforcement anti-skid bionic foot comprises a sliding wheel, a reset device, a front support leg and a rear support leg, the sliding wheel is used for detecting the sliding condition of the foot end, and the direction of a tangential friction force is changed into the positive pressure of the support leg, so that the self-reinforcement anti-skid effect is realized. Meanwhile, the front support leg and the rear support leg are of a multi-section coupling structure, the foot-ground contact area is increased along with increasing of positive pressure, the stress position is changed, and dynamic self-adaption of foot-ground adhesive force is achieved through a mechanical device. A new driving part is not introduced, the structure is simple, control is convenient, the device is suitable for large-gradient uphill and downhill of the foot-type robot, the passing capacity of the foot-type robot is enhanc
