Ground-based experiment of human locomotion in microgravity needs to partially compensate the influence of the earth gravity. This paper presents a novel design and preliminary experiment of an active suspension gravity compensation system, which can apply a desired constant vertical force at human body for physically simulating human walking in microgravity. The system composed of a passive static...
Rehabilitative robot is a new technology that has been developed rapidly. The robot is used to rehabilitate patients whose arms are injured or have difficulty in movement. The robot can move the disable arm in both horizontal and vertical plane, and train the shoulder joint and elbow joint. The human arm is simplified to rigid bodies and rotors. The robot's structure and dynamics are analyzed. Including...
Assistant robotic leg is a kind of robot designed for patients whose legs are injured or have difficulty in movement due to illness (i.e., diabetes, after-illness of the thrombus, etc). Each side leg has one degrees-of freedom motion at the hip and one degree-of-freedom at the knee. It is tied to the patient's two legs to help them practice walking. Based on generalized coordinates, the kinematical...
