Re: Wireless Packet Drop during competition

This occurred for us a few times during early playoff matches. Looking at the logs, voltage drops and packet losses were occuring at the same time. We never lost control for more than a few seconds though, and FMS showed communication with the robot the entire time. It seemed to occur when we accidentally drove our lift down on top of another tote, tipping the robot up and drawing a lot of current. After adjusting driver performance to eliminate the chance of that, we never lost an abnormal amount of packets. It was then tested while tethered in queuing, and we could cause packet loss by stalling our lift motor. We still aren't sure why this is causing packet loss.
