A novel moving mechanism based on three-dimensional Hilbert curves is proposed, combining mathematical curves with mechanical design. The Hilbert curve first-order mobile mechanism (HFCM) moves through seven actuated joints and is analysed for stability and kinematics. Its ability to walk statically, rotate, and climb stairs is experimentally verified.

This paper presents a novel rehabilitation mechanism for patients with unilateral motor deficits. Its core principle is "the sound side drives the affected side", using a single-degree-of-freedom mechanical system where the patient's healthy limbs power the movement of their impaired ones. The device consists of an eight-bar leg mechanism, a six-bar arm mechanism, and a back transmission system to ensure coordinated contralateral motion. Design validity was confirmed via simulation and a prototype.

In order to lessen the impact on the team of rehabilitation practitioners and provide patients with a higher-quality rehabilitation process, an ankle rehabilitation robot based on a parallel mechanism is proposed. The feasibility of the ankle rehabilitation robot proposed in this paper is proven by analysis, which lays a foundation for future human–machine experiments. It can act as a reference for future research of the ankle rehabilitation mechanism.

China is one of the first countries that produced textiles in the world. It has designed and developed a variety of equipment to facilitate textile work. However, due to unclear descriptions in the records and illustrations, a variety of designs with different structures may have been produced. This paper briefly analyzes the structures of textile mechanisms and explores the degree of freedom of the mechanisms to find feasible designs in line with functional requirements.

Aiming at the complex control system of a quadruped robot, a leg structure of a quadruped robot was designed based on mechanism synthesis. The innovativeness of this robot is that it can achieve a special gait driven only by a single motor. Simulation and experimental analysis prove that the mechanism is reasonable, reliable and can meet the requirements of linear walking and climbing. The conclusions of this research will be useful for application in field of single actuated quadruped robots.
