Someone has build a steam powered R2-D2:
The first robot that I ever built, was a R2…. out of legos when I was 5 years old. So after building over a dozen steam powered contraptions, when I “grew up”, I knew I had to visit my old friend R2. I love machines with personalities and charm. You can love or hate StarWars, but everyone loves R2. To many of us, R2D2 was our first introduction to robots, he’s a swiss army gadget bot with charm, who always saves the day. It just doesn’t get any better than that.
I disagree. It isn’t possible to hate StarWars (the original three films anyway). Really nice idea though.
