The sixth-grade science classes at our school built a Lego Mindstorms EV3 Robot. While completing this project, we also wrote computer programs to move the robot. Then we used a USB cord to connect the robot and run our programs. We experimented with different speeds, turning, sensing a certain color and also having it make sounds.
Another great experiment we tested on the robot was the Great Escape. We had to program our robot to sense a certain color, back up and try to find an open space in order for it to escape an area.
We finished up by programming the robot to do more creative things that were not included in the instructions. This was not as easy to do, but since we followed the directions carefully for the other parts, it was not a total challenge. You can buy the robot on your own and they cost about $350 (visit the Lego website: lego.com). We loved building this robot and always looked forward to getting to science class to work on it.
