In some entertainment media I had seen, they were used to portray the evil rogue SecUnits who menaced the main characters. Not that I was annoyed by that or anything. It was actually good, because then humans who had never worked with SecUnits expected us to look like human-form bots, and not what we actually looked like. I wasn’t annoyed at all. Not one bit. I had to run back the drone’s camera feed to catch up, I had been so busy conquering that burst of non-annoyance.
