I will have to agree that you can build a clone for about $500 (less radios -- unless you have found a much cheaper radio than I could find -- a radio that works I mean).

Unless you pay yourself ;-)

Yes building a clone controller was fun to on some level, but it was also a lot of work too (especially the high current area where heavy gauge wire and tons of solder were required -- the smell gets in your hair and you smell it all day!)

All in all, I am glad that FIRST is making arrangements for us keep them this year.

When you think of all the teams that have reverse engineered that board, there were many many many man-hours of duplicate effort.

With the controller available for sale, perhaps teams might even be able to let there programmers have the controller long enough to write some better code.

As for me, I am pressing our programmers for a robust PID control loop scheme for position control of robot arms.

May your poles never cross into the right half plane!
