Meet UPnRIDE: a wheeled robotic device that allows quadriplegics to move from a sitting to an upright position and keep their balance while moving. By allowing users to stand up, UPnRIDE counterbalances the impact of prolonged sitting. With automatic balancing, users get a safe ride uphill.
UPnRIDE can negotiate a variety of surfaces, sidewalks, and slopes. It automatically responds to obstacles. More info is available here.
