LEGO Mindstorm {by R}

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!

LEGO Mindstorms: The Tritimer {by R}

This is my Tritimer. It is a start/stop timer that counts minutes. As you can see it is built out of Lego Mindstorms.

I called it the 'Tritimer' because it has three sections in it that slow down the speed so that it will take exactly one minute to spin around a full circle.

I have used no programing in this build because we can't get the programing software on our computer. I have used the trial and error method with my mom as timer. If it didn't go correctly, I would just tweak the gears so that it would.
