Technical Examples

The disclosed invention used power-assist wheelchair hubs and an array of sensors to provide obstacle-avoidance features on a wheelchair. In a power-assisted manual wheelchair, the traditional rear wheels are replaced with motorized hubs that magnify the force applied to the rear wheels by the user. The present invention uses sensors to detect obstacles and drop-offs near the wheelchair, and uses the power-assist hubs to alter wheelchair movement in response to these sensor readings.
