The annual Robot Fashion Contest in Osaka, Japan is scheduled for November 24th.
It's one robot competition that depends more on style and beauty than on technical merit or raw power. "Performance" takes on a totally different meaning.
Competitors are judged on esthetic factors, and the rules are fairly free and open. While there are the usual restrictions - like no extreme weapons, gunpowder, gasoline, and the like - the robots can use props, background music, and even assistants (human or otherwise). Most of the robots are typically humanoid, but the rules allow you to enter other types of robot designs.
Did I mention there are PRIZES? Some top competitors will walk away with over USD$1,000 - which I'm sure they will spend to buy more servos and other robot gear.
