I felt bad not drawing Mercie this may for my partner . She's a medical robot based on a sheep! I had a go at drawing an earlier, more chrome-like version. My white paint pen was getting extra blobby, though. I think the heat was drying and cracking the paint a bit too quick, as I had the same issue when I did a golden version:

Gold pens said no.

Many years after humanity had passed; the medical bots still roam. Unlike the many 'kill all humans' robot stories of the past; these robots remember their rules to protect organic life. They focus on how to preserve and cure the diseases that wiped out humanity, even if they never come across a human or remember what their symbols meant.

Then I doodled some random robots. A secretary/librarian bot and a worm bot for digging, excavating and fixing tunnels or pipes.
