Hey guys and gals, I know you’ve probably heard of UFC and PRIDE, but what about robot bloodfighting? just do this: check out http://www.sciencetoymaker.com and http://www.paperrobots1999.com for plans and methods to build and animate a robot, then add a motor and a multi-direction alternating manipulation servo (you can build one with household materials) and a mag card as the brain, program the robot to do BJJ, MMA, etc, then loose two on each other and watch them fight! (WARNING: THE DETAILS HAVE BEEN OVERSIMPLIFIED)
