Abstract:
Disabled people generally want to stand on their own two feet, and achieving mobility is an important step in satisfying that desire. A steering-operation unit for disabled people with disability in their arms was developed and experimentally evaluated. The unit consists of a set of load-cell sensors, one for turning right and one for turning left. The driver steps the right or left load cell to turn the car right or left. The magnitude of the driver’s stepping force is converted to a voltage and input to the power-steering motor. The angular velocity of the steering wheel corresponds to that voltage. As a result of this configuration, the driver can drive a car just by moving their foot and intuitively selects the load-cell they must apply by foot to turn the car. Experimental results using a standard car fitted with the developed steering operation unit show that disabled people can drive the car with their foot in a manner close to that achieved with a steering wheel.
