If you have bare minimum resources and no idea what to do, eliminate the non-mandatory parts of the game. If you can cross a few defenses, that's useful. Retain the ability to go under the low bar and cross a few others and you'll be able to contribute to most matches even without the ability to handle balls. If you have spare resources and want to handle balls, just being able to pick up a ball and spit it out back in front of you onto the ground is still valuable - this will let you move balls around the field, pass them to partners, or score in the low goal. You can still be competitive and have a robot worth playing with even only accomplishing these few tasks.
