Hugh,
You are correct that the power does sag during a match. However, these are generally short duration pulses. I would expect that the sensors have some power supply immunity built in that will allow them to survive the short pulses. Since I have no robot system experience with these yet, I cannot tell for sure if we will see problems. We can only wait and see what teams report. I will check with Kate this weekend and see if she did any testing.
Andy was correct in calling you on the 24v power. The rules are specific that the 24 volt output can only be used for the Crio and one 24 volt solenoid module. that about maxes out the current ability of the regulator.
