I really agree with you on this point tonight, giant robot with big shape might find it difficult to be mobile so easily.
Nature faces the same constraints. It's why the largest animals are aquatic, not land dwelling.
I agree with you too on this the largest animals are set live inside water, never get to think of that for once, but thanks to you I really get the picture. Getting a moderate military robots in height will be more better and work perfectly well and ain't it purpose well enough. I can't wait for your decision on this
