This is not my favorite simple bot, but it has some nice features. I especially like the light sensor mount as it gets the sensor close to the ground. Give it a try and see what you think! This is my first attempt at putting together a set of instructions for a model build. Please feel free to send me some feedback and let me know how they worked for you.
