Well, the human body IS pretty remarkable- silent, able to repair itself, covered in sensors, and capable of finding its own sources of chemical energy. And, of course, intelligent in a way no computer is yet. Robots today are doing their best to copy us at everything from manipulating objects to eating (look up EATR, a robot that is supposed to consume organic matter for fuel). Someday those 'bots will catch up with us, though.



A society with intelligent robots, hyperdrive, and replacement limbs as capable as the original body part should be able to make some nimble robots for combat. All the droids are far clumsier than you'd expect- C-3P0 was a home build, I guess, but even the astromech droids seem to be designed to be harmless and clumsy. Maybe this is a cultural thing, droids are a lowly slave class in the SWs galaxy, so they tend to build droids that aren't too Terminator-like and threatening for their owners? C-3P0 isn't really good for anything but translating duties, and astromechs seem to be designed for snubfighter hangers, with those clumsy wheels.
