Re: Brownout behavior - alternative design goals
Some thoughts:
1. It will always be possible for the roboRIO to have less power than it needs to run, so load shedding features will continue to be useful for the great majority of teams.
2. Might be possible for the roboRIO to tolerate longer periods of low voltage. This would be a software change. That said, robots operating for extended periods at 7 volts are visibly sick.
3. regulating the input power would require alternate means to detect battery voltage. Analog sidecar anyone?
4. As FTAA, the only way I knew a robot was in brownout was to go stand behind the drivers and watch the display. We need to make brownout on the robot more visible, to avoid situations like the one Joe describes. Ideas:
a. FMS field monitor should show "brownout count" statistic
b. DS software should have a brownout indicator that stays lit if there's been a brownout
c. DS stack light should change state for a second or so when there's a brownout
