Love the idea that Humans like dinosaurs too much and keep making robot versions of them.
While classic sentinels are used to contain/kill drones, other types of Sentinels are used for broader reasons. Like V.021, a water-based maintenance robot. Hind claws separate like a duck’s foot, using giant paddles alongside a large lightweight tail to move about. Their front paws are for repairing underwater cables and whatnot. They’re also used as WiFi hotspots for data transfers. Oh, pollution control was more so a JCJ promotional tactic, they don’t really do much other than put trash back into trash cans or pull up sunken loot. Pre-apocalypse Copper-9 variants don’t have mouths… post-apocalypse they are very different.
Back in the day they were popular among kids because cmon, it’s a friendly spinosaurus.
