"The Stupid Robot Contest is an annual show held by Meiwa Electronics to determine whose robot is the silliest. There are just three criteria that a robot must meet in order to be entered in this contest:
1. It must be mechanical
2. It must be completely useless from a societal point of view.
3. It must make people laugh.
Pictured above is Papa Robopucho, a disfigured little box bot that plays the red-flag-white-flag game by himself, and then occasionally topples over and cries for help.
Some of the other contestants last year were a chorus of pregnant wife robots, a child robot that did push-ups, and and a "moe" robot dressed like a maid from a maid cafe."
