Wheelchair

The Freewheel wheelchair is aimed at keeping tabs on user's physical activity, with a sensor array that measures things like speed, distance, acceleration incline and decline and collates it into a smartphone app.

Unlike other stair-climbing wheelchairs we've seen over the years, the B-Free Chair relies on a set of robotic "pedrails" that look almost like skinny tank tracks. These articulated pedrails allow the electric to grip the staircase firmly as it navigates up or down.
