Design and development of a planar robot for upper extremities rehabilitation with visuo-vibrotactile feedback

This paper presents the design and development of a planar robot for upper limb rehabilitation. The aim of this system is one hand to obtain information of people's upper-limb trajectories through the use of two robotic arms conformed by planar robots in order to use this information in the analysis of the movements performed by the patient during the rehabilitation. In the other hand, this system is used to correct their trajectories movement using a vibrotactile stimulus to accelerate the rehabilitation process of the patients. The results indicates that this system have a big potential for patients and therapists during the rehabilitation process.
