3-D Rehabilitation Systems for Upper Limbs Using ER Actuators/Brakes with High Safety: "EMUL", "Robotherapist" and "PLEMO"

Rehabilitation for upper limbs is important for elderly people, people who have suffered a stroke and so on. In recent years, the needs for rehabilitation support systems are increasing, which use robot technology and virtual reality technology. Applying these technologies make efficient rehabilitation possible. But there was few rehabilitation support robot system for 3-D training with high safety. So we have developed three different rehabilitation machines for upper limbs: "EMUL", "Robotherapist" and "PLEMO". In this paper, we introduce the recent researches of each robot.
