A lack of wheelchair accessibility makes it hard for disabled people to maintain independence. That’s why a group of ten art and tech students from the Swiss Federal Institute of Technology and Zurich University of the Arts has created a wheelchair that uses wheels for cruising and rubber tracks to climb and descend staircases.
Described as a “Segway crossed with a tank” and as having “unparalleled stair-climbing capabilities“, the all-electric SCEWO BRO (before: Scalevo) has retractable twin tracks that descend from its undercarriage and pistons that tilt the chair back – and it can move at a speed of one step per second. Tests have shown that it can be driven on almost every staircase, however steep. The creators hope that it will eliminate the need for access ramps and stairlifts.
It seems so simple, yet it’s never been done before. Watch the SCEWO BRO climb stairs with ease:
