If this is a prototype for possible FIRST use, I would say that +/- 1.0 inches is sufficiently accurate. If your actual design during season requires more than that, it won't be very human friendly.
Now, purely for R&D it's a cool idea, but don't think that such accuracy is always required. Your manipulator should be designed to allow substantial amounts of inaccuracy.
