This little Mousey Project is featured in the book Absolute Junkbot Guide for Beginners. It has the ability to seek out light and go towards it by utilizing two motors. It can also navigate by using a collision sensor that causes Mousey to reverse and take off in a different direction. A great project for beginners!
