Re: Stumped on Communication Issues - We think it is/was our radio. Details are insid

If you will post a log file or two where your issue presented itself, I'll be happy to see what its info supports. I completely agree with Frank that your radio should not do that and is at least one of your issues. As you well know, the robots are not one-trick ponies, and there are plenty of opportunities for Murphy to introduce himself and provide you with a problem to solve at the actual event.

To the comment on the Weidmuller connectors, I've CSA-ed two events already this season, and plenty last season, and the connectors that are almost always causing "connection" problems are nuts and bolts and sometimes barrel connectors.

About 70% of the robots that lose power are due to the battery terminal connections or the main breaker connection (nuts and bolts). The input to the PDP is far less common, but I see loose ones at each event. The radio barrel jacks are probably next on the list and sound more like this robot, where the RSL never goes out, but the robot is waiting on its radio. Next are stray wires causing a short at any of the Weidmuller or the roboRIO screw terminals. Next is a wire being pulled out of the screw terminal, and finally, are wires fraying and/or breaking at the Weidmuller connection. I totally agree with your input on wire management and strain relief, but I'm not sure what aspect causes you to call them finicky?

By the way, some of those connectors are made by Wago.
