Just because.  Yup, that’s kinda what the Cythbot is all about, which is being a kick ass Guitar Hero player.  Ok, so it’s actually a bit more about robotics but beyond that it can play the crap out of Guitar Hero.  Using a combination of a camera, computer and “pneumatic fingers” fingers, the Cythbot is able to read the on screen queues – in this case it’s the colored Guitar Hero buttons – and play them accordingly.  Check the video below for a complete demonstration.
