Stroke is the primary cause of physical disability resulting in motor dysfunction. Rehabilitation robots are employed to automate repetitive goal-oriented tasks, and strengthen neural pathways. The portable robot built by our team in collaboration with Quanser can be programmed to aid therapists, and assist upper-limb movements to deliver rehabilitation. In this project, various limitations that currently exist are overcome. First, movement assessment in rehabilitation is usually subjective, and lacks quantitative measures so adding proper sensing mechanisms bridges this gap.
Haptics is a growing area of robotics in which users physically interact with dynamic real/virtual environments via active robotic hand-controllers, known as “haptic devices”. Recent emerging applications of haptic technology such as rehabilitation or surgical training simulators require stable high-performance human-to-human interaction in real/virtual environments. Such haptic interaction requires powerful high-performance haptic devices that can produce large force/torque levels suitable for human-level interactions over sustained periods of time.
