Well...this is my first attempt at building a robot. Right now it does basic object avoidance and drives around...woohoo! I'm going to continue to tweak the code to refine his object avoidance. The next thing I'm going to do for him is build a remote control that will have an LCD display and dual thumb sticks (one for driving, the other to control the head).
