Go to Post Maybe next season I want to develop and test a new metric for FRC scouting: Bumper Quality Rating (BQR). BQR-5: The platonic ideal of FRC bumpers. ... BQR-0: Moderate to heavy use of duct tape. I believe BQR would outperform OPR as a predictor of on-field robot performance. - Nate Laverdure [more]

Re: New Off-season Defenses

I have heard a lot of ideas for a rolling log defense, and I really like the concept, but I feel one rolling log would be impossible to get over. I think that a better design for the defense would have 3-5 rolling cylinders, so it still has challenge, but isn't impossible.

Something like 5 lengths of 1 1/2" PVC suspended across the base on taut paracord?

I like it, but it seems to me that something would have to be added to slow the robots down, otherwise crossing that defense would simply be a matter of charging at it at full speed at which point the defense wouldn't last more than a couple of matches.

This was the strategy for over half of the defenses this year... including the portcullis.

YES! Definitely! This or a Bomb-Omb, or maybe a Chain Chomp. Goombas and Koopa Troopas would probably be good too.

Re: New Off-season Defenses

Just wanted to give everyone a heads up of what I've heard from HQ.

Quote:
Matt, thanks for your patience on this.

We just sent emails to District management instructing them not to supply the full portcullis to off-season events, but giving them the OK to supply the portcullis bases (as you have pictured below). As the game-specific elements stay with the Districts after the season is over, they have control of their own destinies on this.

We’ve also provided similar instructions to AndyMark.

Re: New Off-season Defenses

There is no problem with the portcullis.
I competed at MAR district and even was a field reset volunteer at one of the events. I never hurt myself on it (wasn't wearing gloves either), and I haven't heard of anyone else hurting themself on it. Sure it's possible but after you get a cut once you learn to not put your fingers there. That simple. Getting rid of it because a few people weren't paying attention is ridiculous. With that logic we may as well get rid of all defenses because people can cut themselfs on it.

Getting rid of the portcullis penalizes all the teams (like mine) who spent hours on a autonomous for it. Even if HQ is nit letting people ship it out, make a almost identical defense, that doesn't penalizes teams who built a specific mechanism for it.

If it were in season, you can bet that all of us would be up in arms over this. Hell, look at the reaction when they changed the material of the low bar, let alone got rid of an entire defense.
Since it's off season though, I don't feel quite as shafted that they're not distributing the Port. It's large, difficult to see around when reffing (Particularly when it's in position 2 or 3), and there seems to be a few "major" injuries related to it (Or at least, more injuries than I've heard about from past seasons field reset), and teams have already had a chance to use whatever mechanisms that were purpose built.
And on the plus side, if you take off your Port manipulator, you might now have enough weight to cheesecake a climber on!

I see your points and your certainty not wrong, but I still believe it's not enough of a reason to get rid of it.

I would normally agree with this however we already have a hanger and a pound or two to spare. Another good point though.

There were multiple instances of multiple fingers broken because of the portcullis. That right there is absolutely enough reason to send it to the off-season events.

Had it been sent I would still be considering not running it at the Rumble in the Roads. The last thing I want is one of my volunteers to get a major injury.

I'm not trying to single you out, but I wish people wouldn't have this sort of calloused attitude towards safety. I'm certain the people that broke fingers or required stitches from volunteering have a different point of view.

When a volunteer signs up for field reset I believe they should have expected some level of danger. When I did feild reset this year I defiantly got some cuts on my hands and such (as I expected to), but I didn't complain saying that the rough terrain should be forbidden because I got hurt on it. I put my hand where I shouldn't have and after that I didn't do it again.

I don't disagree that breaking fingers and getting stiches is a little different, however by signing up to volenteer you know what the job is and the dangers it could potentially bring. You know what your getting yourself into.

My solution to this problem would have been after the first time there was a "severe" inquiry would have been to give volunteers an option to not work with the portcullis. Better training for handling it would have helped too. Obviously it's a little late for that now.

Re: New Off-season Defenses

Personnel safety MUST be the highest priority in the design of any mechanism which has the potential to be in contact with a person.

"Nothing we do is worth getting hurt." The most successful companies which I have dealt with in my career strive to operate with ZERO safety incidents. The best record even minor injuries and operate to drive those to Zero as well.

Safety must be a core value of every engineer; should be a core value of everybody.
