For the year, the game takes place in, you can figure it out if you look at Evan's painting. It tells you what year he died (The current one.)
As for the robots, I had some designs for how the robots worked back when I was working on the game's prototype. The designs aren't up to date, but I can tell you this much: The Ai & power source sre stored in the robots head. Anything motor skill related is in the torso. Robots are not common at all in this universe. The Volkovs are the only ones with them & it's only thanks to Nasha & Jacob working together.
