The utility model discloses a kind of feet, artificial leg and robot with limiting structure, feet with limiting structure include: foot front, foot middle and foot rear portion;The foot middle includes: the dorsum of foot and the sole of foot connected with each other;The dorsum of foot is respectively connected with the rotation of the foot front, the foot rear portion;The rotation of the dorsum of foot to the foot front is limited;The rotation of the sole of foot to the foot rear portion is limited.This application utilizes the rotation range of each component of foot middle to limit each component mutually, so that the bionic effect of foot is better.

The utility model belongs to the field of airplane auxiliary dragging tools, and relates to an airplane artificial leg design structure which comprises a main artificial leg and a tail artificial leg. A main landing gear of the aircraft is replaced by the main artificial leg, and a tail landing gear of the aircraft is replaced by the tail artificial leg; the main artificial leg comprises a frame, a movable wheel assembly, a rotating wheel assembly, an aircraft connecting assembly, a steering device and a supporting assembly. The movable wheel assembly and the rotating wheel assembly are grounded, the frame is horizontally arranged above the movable wheel assembly and the rotating wheel assembly, and the supporting assembly and the steering device are connected among the movable wheel assembly, the rotating wheel assembly and the frame; the aircraft connecting assembly is connected to the upper portion of the frame and used for being connected with an aircraft nose bracket. The problem of dragging the aircraft is solved, the aircraft body does not need to be transported to other places to be repaired, and the aircraft can be conveniently moved in a factory after the main artificial leg and the tail artificial leg are installed. The airplane dragging device is simple in operation, easy in direction control when an airplane is dragged, large in rotating angle, labor-saving and high in dragging stability.

The utility model discloses a two-degree-of-freedom ankle joint, an artificial leg and a robot. The two-degree-of-freedom ankle joint comprises a first rotating structure and a second rotating structure, the second rotating structure is rotationally connected with the first rotating structure; the third rotating structure is rotationally connected with the second rotating structure; the rotating direction of the first rotating structure relative to the second rotating structure is a first direction, the rotating direction of the third rotating structure relative to the second rotating structure is a second direction, and the first direction is different from the second direction. The first rotating structure and the second rotating structure are rotationally connected, and the rotating direction is a first direction; the second rotating structure and the third rotating structure are rotationally connected, and the rotating direction is the second direction. The first direction and the second direction are different directions, so that the whole ankle joint has rotational degrees of freedom in two directions, and the flexibility of the two-degree-of-freedom ankle joint is higher.

The invention discloses a lower limb movement assisting system and a control method thereof, computer equipment and a computer readable storage medium. The lower limb movement assisting system comprises an artificial leg, a knee joint exoskeleton and a controller; the artificial leg comprises a shell, a rotating body, a receiving body and a hydraulic damping cylinder; the knee joint exoskeleton comprises a first connecting assembly, a driving assembly, a second connecting assembly and a motion sensor. The accepting body and the first connecting assembly are connected with the broken leg; the second connecting assembly is connected with the shell; and the controller predicts to obtain intention motion information according to the previous motion information, controls the driving assembly to drive the second connecting assembly to rotate according to the intention motion information, and adjusts the damping value of the hydraulic damping cylinder. Relative rotation of the first connecting assembly and the second connecting assembly can be achieved through the driving assembly in the knee joint exoskeleton, namely bending and stretching of the artificial leg are achieved, the damping value of the hydraulic damping cylinder in the artificial leg is adjustable, control of the driving assembly and control of the hydraulic damping cylinder are matched with each other, and a user is assisted to move in more scenes.
