1114's HARPOONS
 
We were wondering what they were building over in the pits.

Regular speed:

Slowmo:
https://drive.google.com/file/d/0BzU...ew?usp=sharing

I don't know what speed that is at for the slowmo (all the guy coud tell me is that it's at 240fps) but I'm pretty sure it's at 1/8x speed or around there.

I don't know if they're going to bother adding a mechanism to winch them back. 1114 x 148 might be enough to outstack any other 3 robots on any other field.

Holy safety hazard batman, how did that get through safety inspection?

Edit: it's a joke people, they are just as safe as other canburglars.

Those are any less safe than poles?

While I understand that this video has been circulating around, I don't think it would be respectful to post it without the explicit permission of 1114.

Poles are somewhat more constrained in their range of motion. Once those harpoons are free of the launchers, they're only constrained by their strings.

Poles are constrained by their connection; the bolts are constrained by their connection. Both can become projectiles if the connection fails.

If a 1/8s bolt comes loose or a 1/8s pole comes loose, I doubt it'll really matter which one it is; both would be equally as dangerous. Maybe the pole more so just for the size of it.

Will these interfere with 1114's landfill mining?

Re: 1114's HARPOONS
 
1114 is a class-act, so I don't doubt that it is safe. I'm actually wondering what safety measures are in place.

Also, I don't expect them to have to prove they are safe to me or CD, I'm just curious.

The #1 priority in the FRC robot inspection process is safety.

If 1114 deploys their harpoons in eliminations, it's because they met the safety criteria of a very experienced and safety-conscious inspection team leader.

Re: 1114's HARPOONS
 
I think I question was asked on the q&a before it closed asking about harpoons. Il look for the actual q&a but short story they said it was legal as long as it had a rope or something attached.

Im not sure. I wasnt there, but if they were doing it in the pits I cant imagine they were super worried about privacy. They certainly didnt ask the guy filming to stop, look away or go away.

Reguardless, Im not going to lie that looks TERRIFYING. I hope that if they dont deploy them in auton that they have something very good to prevent them from firing unintentionally. A harpoon to the ref is not a good way to make friends on the fields :eek:

Once you step into a public venue it's fair game.

Re: 1114's HARPOONS
 
I want to see how these end up being used come elims. if they reel in the cans thats fine, but if they dont. someone might bring across a souvenir with them when they pull the cans from the other side. Which may result in a red card under the right conditions for the harpoon user. Speculation.

I'm pretty excited to see that thing in action.

Whoa. All their eggs in one basket it appears? I wonder if they'll wait until semifinals in case it doesn't work?

It looks like team 900's new robot is ready to go... And I happen to know that it HAS passed inspection!

Doubtful, as average still matters. I think they will wait until finals.

I think they might use it for the last semifinal match assuming they have a good average coming into that match.

It will be 1114 vs 1678 for SF-6

We may be much more likely to see it now with 1114's SideSwipe-mounted canburglar all twisted up after that last match.

After 1114 broke in the second round of the semi's, 900 packed up the robot into the transport configuration... Think we'll see it in a few minutes?

Sure looks like 1923/1114/148 on the field to me...

cgmv123 25-04-2015 18:39

1114 is back on the field.

Racer26 25-04-2015 18:43

Re: 1114's HARPOONS
 
My guess is that the Curie alliance knows that they're likely OK coming out of this match due to the lead they have on 1671/1678/118's average, but also know that the finals is against the same alliance that broke 1114's arm.

End of match edit: SHEEESH. It RTS is right, it will be super close on the averages.

Scored edit: Ow. 1.6 points.

Looks like they won't get a chance to show off the new 900.

Re: 1114's HARPOONS
 
It looked like they were going to use almost every match. They put it all back in transport config but than took it back out.
Can't wait to see an improved version at IRI!

I was thinking about this with my students earlier, and there's a pretty substantial difference between the pole/hooks and these harpoons. While you're correct that a failure can cause the poles to become projectiles, the hooks are projectiles by default. It's not an issue if they hit their target (the hole in the cans), but it can be if they do not. The poles' motion is constrained if they miss the mark, but the harpoons might ricochet. Presumably 1114 took great care to align them to avoid the issue, but if there was a device that was faster is could potentially introduce a projectile with a lot of unconstrained energy.

I was actually surprsied it only came oaround this race. The arms race accelerated pretty slowly (thank goodness).

Re: 1114's HARPOONS
 
As a home observer I'm more curious as to whether the harpoon platforms also winched the cans in, or if it was more of a "Noone uses these cans, you have to outstack us" nuclear option for finals?

We thought it was the latter but apprently there is a winch on them.

I didn't see 900 up close in its final form, but this was in 1114's pit Saturday morning, so I'm assuming some kind of winching was incorporated.

Jon Stratis 26-04-2015 08:12

Re: 1114's HARPOONS
 
There was an incorporated winch... But no way to remove the harpoons from the cans that I could see, short of brute force. I'm pretty sure it was a purely defensive live-action designed to ensure the other alliance did not get the cans and had to stack perfectly.
