Oh, gee, I think I'm rediscovering my talent for vector art. This Robbie the Robot logo actually took me less than an hour to whip up. Hooray for Inkscape and Bezier curves!
For comparison, here's a full-body photo of the original Robbie the Robot, lifted from Galactic Voyager. Only one drawing for now. My only problem with this logo is that it's black-and-white, and I can't think of any other color combination to throw at it. That's what happens when the character on which this is based on is mainly black to begin with. Oh, well.
The font used above is Gunhead Chick, lifted from Blambot, as usual.
