Sorry it took so long, but... school and the internet was distracting me :/. anyways, here it is, the sumobot, you will see more on my NXTLog next week. And yes I made a program file, with a little help with a certain part, you'll see how on the NXTLog. My next project might be a tank or a lawn mower, what I mean by lawn mower is a robotic lawn mower I want to make sometime in the future, im just starting on it. Until then, see ya
