Discussion Based on the Key Parameters About The Structural Design and Improvement Methods of Knee Exoskeleton Robots

In lower limb rehabilitation treatment, the recovery and reconstruction of the knee joint have always been important and difficult points. Knee exoskeleton robots play a crucial role in this area. Patients can use exoskeleton robots to assist in limb movement and carry out recovery training. It can significantly improve the rehabilitation effect, the quality of life, and patients’ lower limb motor function. Early knee exoskeleton robots have many defects and flaws, such as being too heavy, poor comfort, and taking up a large volume. This paper focuses on these key parameters and introduces the latest development status of knee exoskeleton robots. According to the optimization classification for different parameters, this paper introduces the structural design and control strategies of such robots. The optimization degree and practicality of different designs are explored. In addition, this paper also proposes the optimization space of the existing key parameters of knee exoskeleton robots. This paper also predicts some possible future development directions, such as high-performance reducers, soft designs driven by cables.
