I’ve been revising Chapter 2, wherein Penn, the main character, escapes the clutches of Inspector Viruet. The good inspector is assisted by a security robot, a polished black, waist-high device which I describe as a headless, neckless, de-feathered ostrich. I was inspired somewhat by the All Terrain Scout Transport in the Imperial Walkers series of Star Wars. These are the most unlikely weapons of war I have ever seen, but they are surprisingly agile, at least in the movie. My walker has a stun gun, and I may give it a more lethal arsenal. If you were to design a non-humanoid robot for security, what would it look like?
