"This is an excerpt from http://terminator.wikia.com/wiki/T-800

"The T-800’s do not feel pain and they do not have nerves, but they can sense injuries. We believe that the T-800 can do this through the use of impact sensors or as part of the overall sensor "sphere" that the unit generates, approximately akin to counter battery radar. There may be various impact sensors that record localized vibrations in the armor shell and, by extrapolation, "sense" where the damage in the T-800's living tissue is. This data then allows the T-800 to conduct low-complexity self repairs. "

But I always assumed that the nerves were responsible for the T-800's capability to sense injury, not some kind of a sensor in the endoskeleton. I mean, the nerves are used to move the muscles in the organic flesh covering (as we see when Uncle Bob smiles in T2) so is it really so much of a stretch to say that they're responsible for physical feeling, as well?

And I do believe that they feel pain, but they don't have a programmed reaction to it, they only register it and say "Okay, there's where I was just shot. Now save that data so I can go back and fix it later."

And this brings me to this question: when the T-800 was chasing Sarah and Kyle through Cyberdyne at the end of The Terminator, and it was breaking through that door, how did it know that its hand had found the handle? Did it sense that something was keeping its arm from moving there? Maybe there are some kind of sensors in its joints and actuators that can detect stuff like that?

"Don't take everything that is on that wiki as canon."

"Yeah, I know, but still it seems strange that someone would write something like that.

I mean, there's so much counter-evidence, you know? I mean, all they have to do is watch that "Uncle Bob smiles" scene in T2 and "Complications" of TSCC. It is "Complications", right? The one where Cameron talks about feeling? "

"It was easier and faster to open the door that way then to continue to pound on the metal door until it caved in.
