The project I worked on was the elevator. I've programmed it mechanically and manually. It was fun to build because I have always liked doing things with these types of legos. When I was building I had a few problems. I was missing a few pieces. So of course I had to improvise. Even though I had to do that, it still looks really good. Some friends helped me program it, but I built it by myself. This is just one of the small projects. Maybe I will be able to do one of the big projects some time. It is programmed by typing in commands such as: talkto, or setleft, or setright. One of the fun parts is that you can experiment with different things.
