The Youtube clip above is a prototype of a new powerchair developed by two engineers from Georgia Tech University. The chair is described as a "sports powerchair" designed to be optimal in nearly any indoor and outdoor situation. The unique thing about this chair is the ability to adjust its wheelbase to allow for more stability when driving at higher speeds when going outdoors or more maneuverability when driving indoors. The single rear wheel (this chair has five wheels) provides stability at high speeds and when jumping curbs since the rear wheel arm is hinged. Did I mention that the chair weighs only 103 lbs (44 kg)? It is an interesting and refreshingly original concept. Check it out!
