Robots can play Rock Band too!
I decided to turn the Guitar Hero Robot towards Rock Band. The video is playing songs on expert! The results look better than expected, I think the notes may be easier for the sensors to pick up. There is still a lot of dropped notes, which I think can be blamed on all the visual effects strobing across the screen. A more precise sensor may be the solution.
I also modified the sensor rack so each sensor is at a consistent height. This helped eliminate a lot of problems.
