Need help with a fire extinguishing robot

I am planning to build a small scale fire extinguishing robot for a school project and I would like to know if you have any technical help hard ware and soft ware for this project.
The fire extinguishing robot should be able to travel inside a model home (1st floor only) room/rooms and extinguish the lit up candle/candles and come back out.

Sorry we do not make systems, only controllers.
