Creating a Maze Solving bot using AI and FPGA

The main aim is to create a robot which can solve a maze by literally driving through the maze. The bot should be made out of FPGA (if possible spartan 3 starter board) and the bot should be able to remember the path once choosen and should not go back in the same path if it is not [login to view URL] bot can use image recognition if needed and the bot has to be autonomous. Needed with in 30 days from now.
