The prices

The prices for conventional and powered wheelchairs given here are only guides. Anyone who shops around may well find cheaper models available. Similarly, there are wheelchairs that far exceed these prices because they are custom built to match particular needs.

Manual – transit

$99 - $199

Manual – bariatric

$229 - $399

Manual – push rim

$169 - $299

Electric – standard

$1,199 - $3,895

Electric – wheelbase/scooters

$579 - $2,899

Power versus manual wheelchairs

What the future holds

The future of wheelchairs is well illustrated by the iBOT, a powered chair made by a company called Independence Technology. As well as being able to balance on two of its four wheels and raise the occupant, the iBOT can go up and down stairs; climb five inch curbs; tackle rough terrain with a four wheel drive feature; and work remotely (for storage and transport).

While the iBOT is currently available, the Pegasus wheelchair, from the Porsche Design Studio, is still at the concept stage. The Pegasus has just two wheels and uses gyroscopic sensors to maintain balance, and like the iBOT, it can raise the occupant to an upright position.

Other researchers - in Australia, China and England - are also reviewing the principles of robotics and applying them to wheelchairs. One idea in development is a sensor that enables a wheelchair to automatically avoid obstacles in its path. Another proposal is a wireless navigation system that plans a wheelchair’s route.

If technology and production techniques can make such features viable, there is little doubt that the wheelchair user of the future will have greater independence than ever before.
