Abstract: This paper presents the design of a wire-based robot for neurorehabilitation called NeRebot. The robot has 3 DoFs and, basically, consists in a set of 3 wires independently driven by 3 DC motors. The wires support and move the arm of the patient, assuring a safety and easy to deliver therapy. Patients that could benefit from NeRebot are people that present movement deficits from neurological injury or disease. The design of NeRebot takes into consideration problems related to the patient treatment especially during the flaccid phase.
