The issue I'm seeing here is the size of the robots. When you have a large piece of machinery with 120 pound max (and I just KNOW we're going to have a lot of robots approach that limit) that is 28"x38", the balancing problem increases.
Simple communication with the team across the field will be difficult, but the largest problem is how would you pull down the bridge? You can't push down with the greater-than-120 pound force needed to push the other robot up, because your own bot would lift off the ground from the force of the mechanism. So unless you can coordinate driving, simply getting two bots on there won't happen.
