Today I went to a friend's birthday party. On the invitation he asked me to bring the LEGO mindstorms to make robots at his house. When I got there, we set up the LEGO mindstorms right away to make our first creation.
First, we made a hand-held flashlight which is powered by a generator. The generator is a LEGO motor. Motors are closely made like generators. Our second invention was a really strong car. Finally, our third invention never worked because it destroyed itself. It was supposed to walk up the stairs but it got so complicated that every thing went wrong.
It was a fun afternoon!
