Dependendo da sua definição de "gigante", os trajes de Infantaria Móvel de Tropas Estelares (1959) caberiam na conta . As dimensões de um traje, conforme descrito no livro, são:
-
Tamanho: " tamanho do gorila "
you look like a big steel gorilla, armed with gorilla-sized weapons
-
Massa: pelo menos 1 tonelada vazia e até 2000lb com carga total :
Two thousand pounds of it, maybe, in full kit...
...You do not repeat not move when surrounded by a ton of metal with your power dead
... and me with a couple of hundredweight of ammo and sundry nastiness still on me that I just had to find time to use up.
... A bare man weighs less than the ammo and stuff you've expended.
But here is how it works, minus the diagrams. The inside of the suit is a mass of pressure receptors, hundreds of them. You push with the heel of your hand; the suit feels it, amplifies it, pushes with you to take the pressure off the receptors that gave the order to push. That's confusing, but negative feedback is always a confusing idea the first time, even though your body has been doing it ever since you quit kicking helplessly as a baby. Young children are still learning it; that's why they are clumsy. Adolescents and adults do it without knowing they ever learned it — and a man with Parkinson's disease has damaged his circuits for it. The suit has feedback which causes it to match any motion you make, exactly — but with great force.
Controlled force . . . force controlled without your having to think about it. You jump, that heavy suit jumps, but higher than you can jump in your skin. Jump really hard and the suit's jets cut in, amplifying what the suit's leg "muscles" did, giving you a three-jet shove, the axis of pressure of which passes through your center of mass. So you jump over that house next door. Which makes you come down as fast as you went up . . . which the suit notes through your proximity & closing gear (a sort of simple-minded radar resembling a proximity fuse) and therefore cuts in the jets again just the right amount to cushion your landing without your having to think about it.
