Correct. The message we've heard from FIRST was it isn't tested/supported on this year's driver station.

There are other ways to position your robot, however.

Don't remember the exact rules but I'm pretty sure that this is legal but you are on your own to set it up at your driver station and try to keep the area clear while you control it.

Regardless of the method used, one would assume that the Poofs have thought of this eventuality and probably have some sort of back-up plan. Whether that be turning to the left instead of the right, or just not shooting if there's something in their path has yet to be seen - but assuming that they don't shoot unless they get to the end of their path - putting up a goalie bot in front of them is probably a waste of time, since they should be able to get rid of all three balls fairly quickly into the teleop period...

If anything, the fact that 254 can possess all 3 of their alliances starting balls at once is the real advantage here. Who cares if they score them? Just not having to chase one or two down for the first 20 seconds of the match is enough of an advantage.

Re: Team 254 Presents: Barrage
 
Wow... lots of cool stuff going on. I wonder how many cubic inches worth of air reservoir tanks are on this robot.

I've been staring at that top deflector linkage for a while. When the cylinder retracts, it angles away from the shooter to assume a steeper angle, right? At first glance I thought it was for achieving a lower angle shot, so now I don't know the purpose of that thing. They appear to be in their lower angle position for the autonomous shots, which is already a pretty high angle. Maybe they wanted even a higher angle yet for a truss pass.

There's a CIM visible through the smoked polycarbonate whose purpose I cannot discern.

I hope we can qualify for the Championship just so I can look at this thing in person for a couple of minutes.

Thanks for posting and warping my mind a bit.

At approximately 6.5 points/sec it is a bit of a shame that you have to play teleop.

If you were able to keep up the points per second rate from auto in teleop, you would score approximatlely 975 points by the end of a full match.

Wait, if someone does manage to block their auto or they just miss somehow, wouldn't that wicked backspin they have on the ball cause it to roll to the opponents side of the field? :confused:

Re: Team 254 Presents: Barrage
 
Clean robot, as usual! Some clever use of pneumatic linkages and latches, very cool. I like how the deflector for the shooter is just floating up in the air on the end of a big moving frame.

I noticed a sponsor sticker on your robot that I haven't seen before... Team Whyachi. How is that working out? Do you have a rotational kinetic mechanism we can't see, or perhaps a new walking drivetrain?

Gaurav27 04-03-2014 20:39

Re: Team 254 Presents: Barrage
 
A really impressive robot. I like how the design is centered around the 3 ball capability for autonomous. This would definitely provide you with the flexibility to pickup from both sides in tight defensive situations. Amazing as always, Poofs!

I'm guessing that "CIM" in the belly of the robot is actually a Thomas 215 compressor. The motor on it looks a lot like a CIM.

looks like shrink tubing labels. you can buy the label maker (similar to a label maker you can get at Staples...just more expensive) and the shrink tubing off of mcmaster.

That makes a lot more sense. Previously I had only seen the gray colored Thomas compressors from past KoP's.

We have many sponsors this year. Team Whyachi (http://www.teamwhyachi.com/botshop.htm) used their waterjet to cut the parts for our shooting hood linkage and rails, and various small plates. Terry Ewert runs a great family business, and is one of the smartest designers I know. They understand robot competitions from their days winning Battlebots events on TV.

Most importantly, they are super fast. DXF's were sent to them Sunday night, parts cut and shipped out Monday AM within hours. They stock most sizes of aluminum you would need, and can perform other full shop services as needed. They are very affordable because they charge based on actual hours spent, not an upfront quote, and the rates are not too high.

I have known Terry as a friend/competitor for a decade, and had them also do work for FRC190 when I was a mentor over there.

Fantastic robot! Awesome two way intake. Surprised nobody that I heard of tried to block your auto after sharing what it basically does and how. However, as long as nobody blocks that, super effective. Also must be nice to not have to turn around the bot to intake the ball. :)

Thanks for sharing this, I missed this. It probably was a last minute change to autonomous, not an option to use way ahead of time. I would've liked to see them get blocked though. :P

They use it every time they load from the human player. You have to look closely for it, it doesn't open anywhere near as much as you might think.

It was definitely something done way ahead of time. Simbotics was using the Kinect to control the robot. Unfortunately, the blocking stick was on the back of the robot which is why they weren't able to block the Poofs ball's in the matches. The articulating blocker on 973 would have been much better suited to blocking the poofs shot, because it could extend in front of the low goal.

Ah, makes sense. Just curious though, why not drive the robot up to 254 with the backend first? That would most likely be effective, no?

They didn't know which side 254 would be shooting for.

Couldn't this have been scouted for if it's a pre-set autonomous? Also, could they not identify it in time? Based on the reveal video, there is space between intake and the shot in which they could have adjusted the robot to a proper blocking position.

Actually it did happen in Final Match 2, with the claw. That's why the Newton alliance won that match. Also in Match 3 254's balls bounced off 1114's pole (I had an excellent view)--a few more inches and they would have bounced out. Again 1114's claw had 254's intake down but then it released.

See a more extensive description in the Einstein thread under Championships.

254 doesn't always drive to the same side. Generally speaking, they drive towards whichever goal is not hot during the first 5 seconds, then shoot at it once it becomes hot during the last five seconds. But 254 has many autonomous modes, including ones that use Cheesy Vision, which allows them to chose which goal to shoot at on the fly. If you watch the Einstein match footage posted, you'll see that 254 is not running the same autonomous mode they used in their reveal video, but instead one that both uses Cheesy Vision for hot goal detection and drives in front of the 1-point goal before shooting.

Does anyone know what autonomous mode 254 used in match 138? It seems as if it was a driver controlled autonomous to juke 2648's blocker.

I don't know, but based off of what I've heard, something like a Kinetic control is an extremely likely possibility. It would be foolish not to have this option when they already have so many.

That wasn't actually planned -- we think it was the result of gyro drift.

Yeah, I've seen them do it like in this video here.

But you've got to wonder with those huge cylinders if they really do open up all the way: http://www.chiefdelphi.com/media/img...fb3db32c_l.jpg

It initially opened up all the way, but those big cylinders were replaced with smaller ones (with an over center geometry to lock) so that they opened just enough to inbound.

While I don't disagree that CATCHing proved to be not very valuable, 254 DID successfully pitch a couple of CATCHed TRUSS shots to 2056 at Waterloo in the eliminations as part of a couple 60pt CYCLEs.

IIRC they caught a few times in practice, and played it off in the best manner possible (catch and shoot before you could blink).

Re: Team 254 Presents: Barrage
 
I walked over to the 254 when they were sitting around and doing nothing in the Curie queue and got a closer look at their robot's wiring. I even got to touch it a little bit.

I'll be telling my grandchildren about that in 50 years.
