The only thing which is special about this log is that to robot battery drops to 8.5 volts at mostly the first half of teleop.
Is there a reason that it stays around 11.5 volts for most of the second half of teleop?
What I can say from just that log file(I'm without the Log-Viewer on this computer, so I'm only covering the photo you attached), is that perhaps, you should try using new batteries, fully-charged.
Starting a match with 12.8 volts was unacceptable this year for us, we used 4 CIMs for the drive-train and 2 CIMs for the shooter, obviously very battery-consuming. If we had started a match with a too low battery it just would not be able to reach the right speed for the shooter wheels.
