Control System for a Limb Rehabilitation Robot

Limb disability, which in many cases results from disease or injury, impairs everyday actions and limits job opportunities. Treatment consists of physical therapy that requires laborious repetition of recommended motions with the help of an experienced physiotherapist. Robot-aided exercises for repeatable rehabilitation motions would allow speeding up the rehabilitation process and reduce its costs. This work presents a concept of a control system for a rehabilitation robot constructed for this aim. The solution has been verified with the prototype robot ARM-100 for upper limb rehabilitation with the control system based on the assumptions discussed in this paper.
