Abstract A rotating cushioning and assisting mechanism comprises a rotating outward expanding member, an elastic return member, and an inner support heterogeneous member; the rotating outward expanding member comprises a first rotating member and a second rotating member, which enclose to form an expandable compartment; the elastic return member is connected to the free ends of the first rotating member and the second rotating member; and the inner support heterogeneous member is rotationally disposed in the expandable compartment. When an external force drives the inner support heterogeneous member to rotate in the expandable compartment, a work done by the force exerted by the inner support heterogeneous member is converted into elastic potential energy to be stored; when the external force is over, the elastic potential energy is released and converted into kinetic energy to help the free ends of the two rotating members to move close.

Abstract A knee joint mechanism includes a thigh support assembly, a connecting base, a shank support assembly and a locking mechanism. The thigh support assembly is fixed at a thigh of an exoskeleton robot, a first angle sensor is disposed on a hip, and power is provided from the hip. The connecting base is mounted with a second angle sensor. The locking mechanism includes a motor, a worm gear assembly, a locking member, an unlocking member, and a first limiting member. The unlocking member and the first limiting member firmly fix the locking member to maintain the thigh support assembly, the connecting base and the shank support assembly at an ergonomic angle. The motor drives the unlocking member to rotate through the worm gear assembly to realize unlocking. The second angle sensor controls the unlocking member to lock the locking block.

Abstract An ankle joint device comprises a base, an angle adjusting assembly, and a foot support member; the angle adjusting assembly comprises a rotation member and an anti-rotation member, wherein the rotation member is rotationally mounted on the base, and the anti-rotation member is slidably and detachably locked to the rotation member along the axial direction defined by the rotation member; the foot support member is mounted to the anti-rotation member, after the anti-rotation member slides away from the rotation member in the axial direction by a predetermined distance, the foot support member is allowed to rotate at a predetermined angle, and the foot support member is locked to the rotation member to rotate with the rotation member relative to the base after the anti-rotation member slides close to the rotation member in the axial direction by a predetermined distance in a state of being maintained at the predetermined angle.

Abstract The present application relates to the technical field of robots, and discloses a robot control method based on a physical engine. The method includes: obtaining the current first resultant force to which a robot is subjected and the current second resultant force to which a virtual object in a virtual environment constructed by a physical engine is subjected; determining the current motion information corresponding to the current first resultant force and the current second resultant force according to the corresponding relationship between the force and the motion information; wherein the current second resultant force is determined by the physical engine according to the previous motion information corresponding to the previous first resultant force of the robot and the previous second resultant force of the virtual object, and the current motion information enables the current first resultant force and the current second resultant force to tend to be synchronized.
