Hints.

  • Heavier Robots are harder for an opponent robot to pull over the line.

  • If your robot use gears to make its wheels turn more slowly, this can also make your robot more difficult to pull over the line; to do this you would put a small gear on the motor axle, and a larger gear of the wheel axle.

  • Sometimes using more than one tyre on an axle can make your robot more difficult to pull over the line; but this will depend on whether your competition is being held on a table-top or carpet.

  • Sometimes more motors can be an advantage.

  • Have you talked to your teacher/mentor about whether your robot needs wheels at all?
