Wired reports about Cythbot, a robot designed to play Guitar Hero by itself. This robot has a camera with a vision processing system and pneumatic fingers, it can play Guitar Hero both in solo and compete mode and does so pretty well. The robot is capable of hitting an accuracy of up to 98 percent, although it's typically in the 75-80 percent range.
The pneumatic fingers hover over the Guitar Hero peripheral with an embedded Wiimote, which is housed in an aluminum box frame.
Two large displays connected to the system show the notes flowing through the screen from the game and indicates which ones are being hit.
Cyth Systems relied on the light intensity of the pixels, rather than the color of the five basic notes, to guide the device's pneumatic fingers.
"If that light intensity value exceeds a predetermined threshold we know we need to hold down that key and actuate the strum bar after a predetermined delay," explains Ivan Gagne, systems engineer with Cyth Systems in this video, "while the note travels down the screen to the bottom play line."
The idea was to demonstrate Cyth Systems' expertise in integrating different systems, says Andy Long, senior director for the company.
