Consider two teams on a dysfunctional alliance: both race to the same pole at the same time from opposite directions...
One has a 15 lb maxi-minibot...
the other one has a 2 lb mini-minibot...
oooh, the horrible noise.., then...
the maxi-minibot slowly climbs the pole with what's left of the mini-minibot wrapped around the maxi-minibot's chrome hood ornament.
Aaahh, but it's the twisted wreckage of mini-minibot that flattens into the tower plate with no worries about not providing enough force for long enough.
But no points are awarded because the mini-minibot did not use power from its battery and motors to climb the pole.

Can a 15 pounder with a "cow catcher" intentionally scrap off little minibots that get stuck on the pole?
That might be fun to watch.

We design for being on a dysfunctional alliance: all the time.
