Re: Serious bug identified in SmartDashboard/NetworkTables -- robot hangs
I believe we went dead in our first match (and the first match of the regional) due to this bug. The drive team tethered and charged the pneumatics with a dashboard running. I not entirely sure if they changed anything on the dashboard. Then they unplugged the tether and placed the robot on the field. The robot never moved in autonomous or teleop until the driver rebooted the crio through the driverstation. The field people said everything looked ok to them.
After this happened, we added a policy of a doing a hard poweroff reboot after placing the robot and not turning on the dashboard during competition. (we don't need it in during a match). The problem never happened again and we didn't change anything else.
We also had two incidents of unintended acceleration before bag and tag, which might be related.
This is a just a heads up to other teams. We aren't going to look into it further since we have a working process. Losing that match turned out not to be a big deal.
It also could just have been the robot having first match jitters.
