Guitar Hero is a popular video game, and requires quick action and practice on the part of the player to master it. But some folks from Near Future Laboratory has a better way of playing it, via robotics.
The project, known as Scale (link), uses electric solenoids to control the buttons on a standard Guitar Hero controller. There is no detail on the programming aspects of the system controller, but I assume that it is rather trial and error until you get the timing right. Then it is perfect every time, baby.
