All the best robots are small it allows them to put thicker armour on so that they take less damage.

However the best armour Ive seen is air. If you have a large gap between your outer armour and your internal components then it doesnt matter if your armour gets cut or crushed.

Its a balance you have to be small so the armour is strong enough to stand up to most weapons without being to heavy. But with air gaps in vunerable locations so that if they are hit by a really good weapon it will not immobolise them.

Unless you have bottomless pockets and can afford 6mm titanium alround like storm II.
