when our controlls cut out due to power drain, it only shuts out for about half a second...

we too are using all 5 cims...
sometimes when pushing full force, the orange light on top of the robot turns completely off haha
I am concerned about power this year.
Nobody really saw how the CRIO and the power distribution took to the harsh world of high current draw...last year we were all sliding around simply spinning the wheels haha
I'm surprised you're the first to mention it too.

If the robot is cutting out when you're pushing, stalling, or near stalling any of the cims, it wouldn't surprised me if you're tripping your auto-resetting (3 seconds) breakers, or that you are tripping the internal protection if you are using jags.

If you're dumping low enough to cause the Crio to reboot, it's going to take quite a while for it to reset and regain connection. The bridge will take slightly less time, but it will take time.

So next time you are driving, watch your drivers station. When the robot stops, does it reflect a loss of communication (no robot) or a loss of code (no robot code), or does it stay static? That will lead you in the right direction.

If robot communication is not dropped, then I would start considering that you might be pushing the breakers too hard, or your digital sidecar might have the power wired incorrectly.
