Abstract
A vehicle includes a motion sensor and a control processor. The motion sensor optically detects motion of the vehicle with respect to an underlying surface. The motion sensor includes a variable focus imager. The control processor receives information from the motion sensor and calculates location of the vehicle, speed of the vehicle and/or acceleration of the vehicle.
