Slowing down and maintaining control of a wheelchair can be difficult for some users, especially those with poor hand strength and/or sensation. Ramps and slopes present a significant barrier to independent and safe mobility. Collisions, falls and/or tips are consistent with running into an object at too high of speed. A need exists for a braking system for manual wheelchair users that allows them to use their hands more effectively and efficiently while braking.

The ‘Kangan Roo’ is an innovative electric wheelchair design that can automatically contract and extend its wheelbase while in use. By lengthening the wheelbase it becomes a sturdy outdoor electric wheelchair that can ride up and down curbs of up to 15cm in height. By shortening the length of the wheelbase it becomes a neat and compact electric wheelchair, with the reduced turning circle making it suitable for indoor use.
