Re: Using a star configuation for Jaguars on CAN
In our case we needed to use CAN for current and voltage sensing throughout our robot. For example, our front ball magnet would capture a ball and then stall by design with the current held at a constant value so as not to smoke the motor. It could also sense if it had a ball by looking at the voltage being delivered to the motors.
Our kicker would vary it's kicking power by monitoring the current going to the winch as it's being cocked.
We'd love to use the daisy chain configuration if it were reliable. We might give it another whirl next season but be ready to fall back to PWM for speed controllers that don't need all the fancy features.
