Who does the Instructables Robot drawings for the Instructables contests?

For some of the contests, there will be a drawing of the Instructables Robot involved with the theme of the contest. Right now, the Fitness and Watersports contests have a drawing of the robot. They are awesome drawings, and I was wondering who did them? Thanks!

Other users create fan artwork of Robot and other members for a variety of reasons/projects, but all the 'official' graphics for contests and other media seen on the site are all done by the talented Natalina.

I think caitlinsdad is the author of the Robot drawings, but that's just a guess, mostly based on this:

That's what I thought, but I wasn't sure.
