Ditto, and any other new robots mentioned please.
The "clocktopus" is a repair drone. It's an animated object with the robot subtype, though its stats and abilities are novel enough that it's pretty much a brand new creature. Its purpose is to repair other robots, though it can throw down if necessary.
There's a robot whose purpose is to make contact with primitive (non-technologically advanced) cultures. The name escapes me. They're nothing too interesting, but are designed to look angelic. This fits in nicely with Unity's delusion that he is, in fact, a celestial messiah.
The director robot is a humanoid/tank centaur (tankotaur?) that directs other robots. Which you might have surmised from the name. They remind me a bit of higher end modrons, in that they can take over the programming of their lessers. It's implied that Unity uses director robots to indirectly keep tabs on the robotic soldiers that he lends out to the Technic League. Unity's reach ends at Silver Mountain, so the directors are his proxies.
