In recent years, rehabilitation robots which help the neurological impaired patient regain the function of the lower limb via training sessions have been developed with great attention. Since these types of robot interact closely with humans, safety is always the top priority considered in the design. Besides, the compliance of the robot must also be controlled to give the subject the best comforts. To fulfill the above mentioned requirements, a two degrees of freedom (2-DOF) robotic orthosis power by pneumatic artificial muscles (PAMs) based on the human musculoskeletal system is developed in this study. The system is able to track any desired trajectories by using a computed torque control strategy. The impedance controller is also integrated into the system to adapt the robot compliance according to the external force. The feasibility and effectiveness of the developed system are verified by experiments.
