An automated vehicle includes a vehicle body, a power source, one or more motors housed within the vehicle body and in operable connection with the power source, running gear in operable connection with the one or more motors for facilitating movement and supporting the vehicle body upon a surface, and an optical system. The optical system includes an optical sensor for detecting light reflected from the surface and generating an output in response to the light reflected, and one or more light sources, each light source capable of projecting light on the surface. Furthermore, the optical system is configured to regulate an amount of power supplied to the one or more motors in response to the output generated by the optical sensor.
