Do go for a micromouse robot. Its fun with extensive creation for a begginer. You will learn automation, control system and everything in order to implement this. So go for it, top to bottom approach, and solve each small roadblock. When u'll be standing with one finished one, half of ur brain will be occupied with what u desire for. I like to see it working as an automotive brain system, thinking on its own to solve a maze, all designed by me. So go for it buddy to learn.
