  • CAN looks very powerful. I love how you can daisy chain Jaguars together. This will keep wiring simple.
  • I agree, this will be very slick. Unfortunately it won't be available the first year.

  • The Jaguars run on 12V (from the literature). Can you assume they know the robots electrical system will be 12V in 2009 with some sort of 24V transformer for the cRio?
They are aware of all the features of the new control system, and since all the motors are going to be 12V (I guess I can't say that with certainty, actually) it would make sense for the speed controllers to have 12V input.
