Tractor pull

The tractor pull challenge is going to be a fun one. It is not a race of speed, but a race of strength. This is a test of which robot can pull the most weight a distance of 50 cm in the least amount of time. To make your robot able to pull more weight you will need to make your robot a little bit heavier to put some friction on the wheels to keep them from sliding. The gears you would want to put on it are a big driven gear connected to the motor with a smaller driving gear. You might even want to put 2 rows of gears to increase its power.
