Lost Trailers

[gorrilla]

I saw this,

The pins' spring must be getting pushed in somehow....

I never would have figured they could come out, though(being hitch pins)

Lost trailers at Midwest were from people not fully securing the set pin. It has a little spring clip that keeps the pin in, if that is not set, the trailer is prone to falling off.

I don't recall trailers being un hitched at DC; though again, the field crew was amazing and helpful there (though I'm sure all the field crews are awesome)

In one of our matches in GT (Greater Traverse City District), we literally drove away from our trailer in autonomous...

The match wasn't stopped, and the trailer was filled until it literally couldn't hold anymore balls, it was bad, really bad.

I saw it happen once, but I'm only aware of it happening on that one instance the entire regional.

In one of our matches yesterday the trailer came off of a robot right after autonomous mode. It should've been disabled as soon as possible but, the ref assigned to that team was uncomfortable doing it himself so the head ref had to intervene.

Some of the pins and pin holders took a beating throughout the competition. Before our second semi-final match I had to wait at least 2 minutes for them to find us a usable hitch pin.

We lost it once because of our fault. It's not that bad.

at mwr this happened a few times where they didnt get disabled. i dont know why the refs didnt immediatley disable them but at the end of the match the trailers were spilling balls out the top. not a good thing for the alliance that it happens to.

If the trailer falls off the robot, that should be a field fault, and the match should be replayed.

I really don't understand why the poor team that has this happen to them would get disabled. Then the alliance is penalized twice for the field breaking?

If the team connects the trailer to their robot (which generally is the case), it's not the fields' fault (if it wasn't properly secured). If the force of a collision happens to cause a properly installed pin to come dislodged, that's just bad luck. Independent of how the trailer is lost, <G35> requires the robot to be disabled.

If it is because the pin or trailer tongue broke, then I would agree. If it was because the team improperly installed the pin, then that is their own fault.

I grew up on a farm, and we never "trusted" these types of pins having them "jump" out on occasion. I never lost a hitch pin though that had a secondary cotter pin properly installed. Small bumps while undertension can put a surprizing amount of vertical force into a hitch-pin.

If a team installs the pin with the clip over the end of the pin, and it manages to come out, how is that their fault?

Are volunteers/refs/the FTA checking the pin prior to the match starting? Maybe they should be, and that would eliminate the problem. If they were to check, and ok it and the trailer subsequently fell off, then it's a field problem, not a team problem

Yes at GSR they checked every robot at least once...

This doesn't sound like something that should be happening at all, and I was surprised to hear that it's such a common problem. Does anyone have a picture of the pinning system used in competition?

This is a competition trailer, with the same pin they use at competition.
