Re: What to do when your robot loses Comms

They can tell if it was a complete power cycle, brown out, or if the radio lost comms. In our case, the radio would reboot. Our's was related to a strand of wire that was shorting when getting hit hard. We put a new radio plug/wire on it and it was fine.

I was also told by the CTA that some barrel power connectors are not as good at others. They had a couple issues where it was this. We also hot glued ours in just to be sure. We did notice the new one was a much tighter fit then the one we were using. We also put foam (noodle rings) on top and bottom of the radio to stop vibration/shifting.

Lastly, they stated that with the rough hits, the small fuses ( yellow I think) on the end of the power distribution board would work themselves out slightly. I would push on them every couple of matches along with all the others just to make sure.

If you can power it on in the pits and bang/wiggle every wire you can access. If you loose comms for roughly 1 minute, it's likely the radio. I think a full reboot of the roborio take longer.

We did have 2 smoking robots at FLR - one looked pretty bad - melted a big bundle of wires.
