NXT Projects: Silly-Walking Robots and Going the Distance

This was our first day working with LEGO NXTs, and our first assignment was to make them walk. Which, as it turns out, is not as easy as it sounds. This was a really quick, in-class assignment so I didn't remember to take video, sorry!

The next part of the class we built robots with wheels (a little bit more elegant than the jerking, walking robots). We had to make these robots drive a certain distance and stop before hitting a pedestrian:

My partner as I used ultrasound to detect where our pedestrian was. As we got closer, the car stopped. At first, we had the car go directly up to the pedestrian and stop. The car's momentum made it hit the pedestrian, so we made it stop further away from our little guy.
