Power steering for a walking frame
The front castering wheels were replaced with wheels in straight forks. Power is provided from a cordless drill with two rechargeable batteries. The client steers the frame by using her thumbs as she grips the bar of the frame; by pressing on one switch the wheels turn to the left and on the other, to the right. A mirror tells her the wheel direction by giving view of a pointer attached to one of the wheel forks. An unlocking system allows the two rear wheels to caster, enabling a carer to help the client cope with very sharp turns.
The client is now able to steer her frame along corridors at university and at home.
