Christopher's Gifted Class project

Christopher has a project for his talented and gifted class. I'm not sure what the assignment is, but he has built and programmed a robot for it. He'll be showing it off in a week or so. For Christmas we got Christopher the Lego Mindstorm system. It's a pretty cool robot building kit. For the project he built a scorpion. He programmed it to start walking when it hears a loud sound. It takes several steps and then strikes out with its tail. The tail is a scissor construction so it extends out and hits the floor in front of the creature. It then laughs a maniacal laugh. Christopher did all this by himself. We've had a problem getting the program to loop, which is what he wants. So I'll have to help him figure that one out.
