paper: FRC #33 The Killer Bees 2013 Software - BuzzXVIII (Buzz18)

[apalrd]

OK, finished the 'CulverDrive' paper and attached it with example code.

What is CulverDrive?
-Improvement on previous 'Cheesy' and 'Halo' style drive systems, which are already used by many top teams
-Utilizes Logitech F310's round joystick boundary to provide a virtual steering wheel effect, allowing the driver to gracefully navigate the field
-Utilizes a mathematical algorithm similar to the 'Cheesy Drive', the intent in design was to replicate the functionality of a 'Cheesy Drive' using a real steering wheel on a joystick.
-Award-Winning (Waterford 'Innovation In controls' and Championship 'Quality' specifically noted CulverDrive in judge comments)

What does the zip include?
-LabVIEW source code, direct from Buzz18 software release, plus required BuzzLib interpolation blocks (prelookup and interp_2d)
-C source code, used in simulation and intended for Vex targets and readable without LabVIEW. Unfortunately it does not directly run on Vex because RobotC does support the C language very well.

Does it require a Logitech F310?
-In short, yes. The Logitech F310 has a circular joystick boundary, which is key to the algorithm. It's also smoother to drive than a square of octagon.
-The Xbox 360 joystick has an octagonal boundary, which will not provide the desired effect nearly as cleanly. The Logitech DualAction has a square boundary, which will not work very well at all.

As always, feel free to ask questions regarding any of our software.
