Abstract: In this paper the Sit-to-stand (STS) trajectory of health persons is researched. First an STS biomechanics model is established. Then, the mechanical structure of a lower limb rehabilitation training robot with several degrees of freedom is designed and optimized. Finally, each joint angle in the STS process is assessed by experiment and is used to instruct the control of the designed lower limb rehabilitation training robot. Experiment results show that the STS biomechanics model can provide effective reference for the lower limb rehabilitation training. The designed mechanical structure conforms to the mechanical performance requirements with light weight, less space occupation, low cost. Therefore, it is suitable for clinical application and product promotion.

Key words: mechanical design, biomedical engineering, lower limb movement rehabilitation training, structure optimization
