Dynamics analysis and simulation of a new 6-DOF lower limb rehabilitation robot

摘要

This paper proposes a new hybrid (parallel–serial) 6-DOF lower limb rehabilitation robot including two mechanical legs and an adjustable seat, which could train in sitting, lying and standing three postures. Each mechanical leg consists of hip joint, knee joint and ankle joint. The dynamics and DOF of the robot are analysed, and the result is verified by the software ADAMS. The result lay the foundation for prototype build in future.
