Teaching Robots to Punch

Well, you can't give a software engineer a Rock 'Em Sock 'Em Robots set for Christmas and expect him to be satisfied just pushing the little manual levers. I mean, it even requires convincing someone else to play with you.

I was amazed to see that a quick Google search turned up only 1 other instance of anyone trying to automate a Rock em Sock em game, so I set off to try it for myself.

Once I managed to pry the sonic welded pieces apart, the Red Rocker's torso was almost a perfect fit for Pololu micro DC motors, so giving my Red Rocker some muscle was fairly straight forward.

This setup let me attach the motors straight to the bicep, which definitely feels like a much cleaner engineering solution than just putting servos onto the existing levers.  I put together a quick demo to prove that the motors pack a big enough punch.  Enjoy the 'gun show'.
