My recommendation is that you take what you have and then... Fudge it! Go Old School on that Robot! Wing it. Make it up.
Take a basic frame, add what you think it should have, and toss in an AI control circuit. Make the shape so that it will fit through a hatch, add some magnetic/sticky traction surfaces for locomotion, some extending manipulator arms that can use human tools, and voila.
Your Rossom's Robot Rentals just bought a few Rostrums Rengineering Robots, a custom firm that just started building stuff and doesn't follow the rules (Hint, HINT), and one is acting kinda funny, like *HINT, HINT!).
Seriously, if you wanna do a PC robot, feel free to not be constrained by the rules. Use common sense, but have... FUN!!!
Just don't forget to recharge... and stay away from Space-mart batteries...
