cRio Constantly Rebooting

[Jared Russell]

Dale and Chris,

In the absence of our inability to isolate any other failure modes on our practice machine, we are arriving at the same conclusion: at times, we are simply asking too much from the battery and browning out the cRIO and/or the radio. Other teams have used successfully 6-motor drive setups geared for similar speeds in the past, but as you pointed out, this was in the IFI era when we often had backup batteries (even before backup batteries, does anyone have data on how low the main battery has to go before the RC reset?).

Brian,

A voltage ramp to the motors is one fix we did talk about. However, as you pointed out, this is a band-aid. For Philly we will swap out our ~13FPS drive modules for ~10FPS drive modules and run without the RS-775s (at least until we verify that we have corrected the issue). With our howitzer of a human player, we seldom ended up making dashes of more than 15 feet at a time anyway, so we feel this fix has a high probability of resolving the issue while not impacting our scoring ability.

Greg and Al,

Check your PMs.

Thank you all for your help!
