Abstract

A system for guiding a vehicle is provided. The system includes multiple paths on a surface, wherein each path is defined by ultraviolet (UV) reactive paint configured to emit visible light in response to UV light. The system also includes the vehicle. The vehicle includes a UV source configured to emit UV light, a sensor configured to detect the visible light emitted by the UV reactive paint of a respective path of the multiple paths, and a controller configured to guide the vehicle along the respective path based on a wavelength of the visible light detected by the sensor.

7. The system for guiding a vehicle of claim 6, wherein the different wavelengths represent different speeds for the vehicle along the respective path, and the controller is configured to adjust a speed of the vehicle along the respective path based on a change in the wavelength of the emitted visible light.

8. The system for guiding a vehicle of claim 6, wherein the controller is configured to cause the vehicle to spin based on a change in the wavelength of the emitted visible light.
