For example (over engineering it): If your robot weighs 200 lbs and you have 4 support beams holding that weight, then each beam will receive (ideally) 50 lbs. Basic mechanical physics tells use that the beams will be receiving a compression from the weight. Go to your school (or local) lifting room and put a 50 lbs weight (or 50 lbs equivalency) on the top of some aluminum of about the dimensions you want to have for your support beam. If it notices the weight at all then beef it up.

Most aluminum isn't that weak. Do take careful note of which alloy you use, because depending on the abuse your cart takes, that will make a difference.

I was thinking of old fashion emperor style transport. 4 rookies on each corner.

I don't think the field volunteers would be happy about a "cart" involving 16 rookies (though i'm sure software would love it).
