Abstract

Disclosed are methods and apparatus for commissioning a light source in a lighting system including a plurality of light sources capable of emitting coded light. An autonomous vehicle with one or more light sensors and a location detector navigates throughout the lighting system. The light sensor detects an identifier encoded in a light source and the location detector determines the location of the autonomous vehicle. The location is associated with the encoded identifier, thereby commissioning the light source.
