It will be quite difficult to hold multiple tetras on your robot because the tetra is almost as large as most robots, and tetras weigh 9 lbs each. If you have a stack of tetras on your robot, you will have balance issues.

I do not see what the problem is of having one of you alliance partners (going to and fro from the loading zones)and keep on feeding your robot tetras in a stack on the ground. The opposing team really couldn't steal the tetras because they are color coordinated... well they could just throw them out of the field, but that would be just plain mean, and not gracious professionalism.
