There are robots, and then there are Cyberpunk robots. This Artoo unit, named R2S2, or R2 Steam Too, is built into an old broken R2D2 Interactive Droid picked up from ebay.
Maker I-Wei Huang, of CrabFu Steamworks, dropped in a boiler, worked his steampunk magic and came up with the coolest steam powered robot we've seen. It runs for ten minutes on a propane/butane mix. Plenty of time to save the rebel forces. Again.
