Snowmobile Race

Program: Easy

LEGO Mindstorms NXT Snowmobile Race

These two "snowmobiles" race each other in a circle around the NXT brick, which will rotate with them on a pivot.  One of the snowmobiles is built to go faster than the other one by using different gears, but the slower one has the "inside line" because its cord is shorter...  So, which one will win?  Well, depending on how you adjust the wire leading to the slower one, you can make it a tie, or one might pass the other, or they might crash into each other!

The construction of the snowmobiles is very simple, so there is plenty of opportunity to try to make them faster or better.
