Design and Analysis of a Multiple-DOF Bipedal Gait Test System

Gait rehabilitation is an important process of medical treatments on lower extremity injuries for human neuromusculoskeletal system. Benefiting from the medical device automation technology in recent years, robots achieve the rehabilitation in a professional, precise and continuous manner by integrating mechatronics, automation, computer science and communication technologies, improving the qualities provided by human therapists, the labor-intensive works. This research proposes a Stewart Platform-based measurement system for human gait rehabilitation and test purposes. Related works are collected and analyzed, fetching a brief understanding of the market. Human gait model is constructed in 3D Studio Max and the CAD model is established in Solidworks. This research forms the mathematic models of kinetics and dynamics and performs the footplate posture simulations by using these models.
