We're a little queezy about giving away the recipe for this robot so soon. We are just rolling it out, so give us some time to get some experience with it ourselves. Basically we are using Labview with the vision tools that came in the 2009 KOP to watch the right places on the screen and determine when a note has passed. I would have to ask our programmer about using another platform. He is a Labview whiz, so he would probably say to any FRC team "if you have access to Labview, why would you use anything else?"

As to servos, in my opinion they would be overkill for this application. This job calls for short, linear, repetative actuations with no variation, just what solenoids are good at. Servos are for having accurate and variable control of speed and position. You can drive solenoids with a simple on/off output for a small fraction of the cost of eight servo systems, and probably with faster response.
