In the future as techology keeps evoloving, robots who look like humans known as androids, humanoids, or even cyborgs (cyborgs from The Terminator series) One Terminator named Cameron in the TV series said she is a rare and special model who has the ablitiy to eat foods as fuel, has the ablitiy to sense things such as touch, feel, smell and taste. Senses are related to the electrical signals that goes into the brain to send you information from whatever senses you use will be the same with the future robots.
Believe it or not, we are not THAT different from cyborgs, only they could be stronger and smarter than us, though.
I'm not saying that since it is science fiction. I am saying that cause it WILL happen. Who knows when, perhas about 50 years from now.
