Given that the marvellous epoch of tweed roughly covers the late Victorian and Edwardian periods, might it be inappropriate to use the term "robot" which didn't exist until Čapek's 1920 story "Rossum's Universal Robots"? I fear this may imply a decidedly less august setting of the grimier post-tweed industrial period.
Perhaps the term "automaton" would be more lore-friendly?
The game isn't set in ye olde vicky/edwardian times. It's sort of an alt present. There might be some screenies around showing wind turbines and other modern thingamajigums.
It's entirely possible to meet people in the UK today who look like they've inherited their wardrobe as well as their country estates, the robots are emulating them, not the past. Sort of.
All the same, if we say please with wide open eyes...perhaps?
