When I set out today to do another post in this thread I actually started out with a completely different droid in mind. However as I poured over my references and searched the web I found myself drawn away from my chosen course and researching the WA-7 service droid instead. Guess the other droid will have to wait for another day.
(we need a smiling droid emoticon)
WA-7 was first seen in Dex's dinner on Coruscant when Obi Wan goes to visit Dex. Her appearance is fairly short, but she's not as obscure as many (or all) the droids I've put in this thread previously. I also try to feature droids that can reasonably be built; that is to say not a lot of flying or impossibly balancing droids. In this case I just couldn't help myself.
Flo's got a lot of Googie (no, it's not a typo.
Googie, not google) or Populuxe in her look. She looks like she could be at home in a Jetsons episode. Somehow it still worked for me and I didn't think she looked out of place in the film. (this image is actually from the Clone Wars animated series)
There were a number of single wheeled, balancing robots in the prequels. The technology to build such things has gotten considerably better for us in the real world, however, I think Flo's little, tiny wheel would make her a bit more than simply challenging to reproduce as a working version. Though I can't help but keep thinking about how it might be done.
Hasbro has released a fairly respectable toy of WA-7, another resource when you can't find what you're looking for in the available images.
