Abstract
In one embodiment, a wheelchair includes a drive wheel, a motor coupled to the drive wheel, and a user input device. The motor, in one embodiment, is configured to rotate the drive wheel. The user input device may be configured to send a signal for controlling a motor parameter. The wheelchair, in one embodiment, includes a caster wheel and a castor sensor configured to sense a caster angle. In one embodiment, a controller is configured to receive the signal for controlling the motor parameter and a signal from the caster sensor and to determine a first turn rate parameter of the wheelchair based upon the received signal from each of the input device and the caster sensor.
