-The Talon SRX is the most powerful (and most expensive) controller and includes its own microprocessor that can offload many duties from the robot computer.  This allows the robot computer to instruct the SRX to perform high level functions such as "run the motor at 100rpm" and the SRX will automatically adjust power to the motor as the load varies to keep it spinning at 100rpm.  The robot computer communicates with the SRX over a two-way CAN communications bus that is particularly easy to wire, requiring only two wires for all of the motor controllers.  The robot computer can issue commands to the SRX and request status.

The robot computer communicates with the controller over a two-way CAN communications bus that is particularly easy to wire, requiring only two wires for all of the motor controllers.  The robot computer can issue commands to these CAN controllers and request status.
 
 The other motor controllers (SR, SP, Spark) are simpler devices that require the robot computer to perform the higher level functions.  The robot computer uses PWM to communicate with each motor controller; the PWM signal specifies speed and direction but is one-way only (robot computer to motor controller).
