Thanks for all the replies guys. I'm really excited about working on the all-terrain vehicle since it'd be a good challenge. The long board also seems like a really good idea.
Again, thanks for the suggestions and I'll see if when I'm done with this project I'll work on something else using the tips you guys suggested (of finding something I'm too lazy to do, then building a robot to do it)
