Best 2010 Lifter
 

So I'm just getting into Robotics and don't really know who to look for as far as teams goes.

What have you guys seen from Week 1 on the best lifting team? (I'm going to post another question about scoring/kicking so let's keep this thread just to the end-game.

Thanks,
TheFish

Re: Best 2010 Lifter
 

Our team went to the finals this weekend with team 78, Air Strike, at the Granite State Regional. They could consistently lift in under 15 seconds. The lift is an arm that deploys and grabs the vertical pole. A powered wheel then rotates and 'climbs' up the pole. I believe there is some video already around on CD showing it.

Simply a thing of beauty to watch it operate.

Re: Best 2010 Lifter
 

525 could consistantly hang. Along with 1982 and 1825.

Re: Best 2010 Lifter
 

From watching on webcasts on Friday and watching the Kettering district regional live, I have come up with a good list of lifters that were consistant, yet quick.

78- I do agree with the previous post, they have a very effective hanger and it's easy to pull off.

525- watching the KC regional was exciting, but when these guys played you waited for the last 20 secs to come. They sit right on the bump and take hold on the top bar, and there off. Most times to make the full lift I took about 10-12 secs. The only problem is they have to get on the bump, I forsee teams trying to push them off or try to block the bump in the future.

2337- The enginerds always have something out of the box on there robot, since there rookie year. This year they have the coolest looking chin-up robot I've seen. They have a huge system that sits on top of the base and it kicks up after they set-up under the bar. It's vey effective, as if only of the two hooks grabs hold it stills gets two points for there alliance. I believe in the 8 matches I watched them play on Saturday, they hung for 2 points 7 times.

27/33-My favorite two hangers are very similar and twice they hung in the same match making it very fun to watch. The easiest way to describe these lifters is to say that, they are close to the likes of what 217/148 had. Both lighting quick and sometimes both lifted up, in under 10 secs. Yet the bees (33) took it one step further by having message written on the bottom of the robot for the crowd to see after they hung themselves. Whether it being "Bee happy!" or "Finals baby!" both these robots have almost perfected the art and probably will continue to do it every match.

Re: Best 2010 Lifter
 

FLR had so many good ones but I think the one that really stood out were 1551 (check out the video from YNN who could hang consistently and fast every match and that ability drove them to the top seed. Team 229 can hang in few seconds. Rookie team 3157 , 1559, 1241 and 1507 were also tremendous hangers.
There were probably a dozen robots at FLR that could hang. We had several matches with multiple robots hanging. As many as three in some matches.
We manage to hang in the last match for the first time right at the end of the match but unfortunate so did 1551 (they would have won anyways even if they didn't make it up).

Re: Best 2010 Lifter
 

1625's lifter was one of my favorites. A few more seconds and they would have tied match 3, I bet. The actual lifting motion is short, getting in place with defense isn't. (Defense before they touch the tower, of course).

148 and 217 _had_ good systems.

2062, 2079 seem pretty neat.

I want to scrap my team's system for a simpler to control system due to stability issues in favor of tunneling...

Re: Best 2010 Lifter
 

I will echo that. I was working on autonomous and the people watching the webcast called over to me and said that I had to check out 27 hanging. I was amazed. It was a great example of how quickly elevation could be accomplished. I stuck around a little longer and watched 33 do something very similar (they were hanging with about 12 seconds left in the match at one point!). The thing that was most impressive was the speed at which both teams went from driving around to hanging. They took the complexity out of lining up and were up in no time. Great job to both 27/33. I can't wait to get a close look at both in Atlanta.

Re: Best 2010 Lifter
 

Just a heads up on why it is so large, that thing is designed so that anyone that could normally hang (off the top bar) can hang off of it instead. The robot was designed to facilitate a double suspension.

And, I would like it noted, the upper structure is most definitely inside the box (except in the last 20 seconds). We don't want no penalties! ;)

Re: Best 2010 Lifter
 

The best lifter at The New Jersey Regional was 25 without a doubt. Their mechanism was both unique and fast, but I won't go into too much detail here. I believed it was dubbed "The Strong Man Hang" by the announcer at NJ...

Re: Best 2010 Lifter
 

Are you saying this because you haven't seen them play in an official match? Or did I miss something about a redesign!?!?!:ahh:

Agree with team 78's beautiful, quick design. I also liked team 151's.

Re: Best 2010 Lifter
 

Lol... What I meant by outside the box was, something completely different than most... Kinda like the boot idea from 2008..

Re: Best 2010 Lifter
 

Both teams removed their hanging arms and used the weight toward strengthening their drivetrain and lowering their CG.

Re: Best 2010 Lifter
 

Both teams decided to do away with the hangers for drivetrain strenght

Re: Best 2010 Lifter
 

There is something else about 2337. When they lock on there is this sound. It just sounds-- strong. I was in the pits and just knew it was them. I don't remember, and maybe someone from 2337 could answer this, could a team like 27/33 lock onto you and then you lift or is your structure made out of square tubing?

Re: Best 2010 Lifter
 

When we go to lock on to the tower we have two pins that are pulled and extend our supports that touch the vertical supports of the tower, that is the first sound you hear. Then our two hooks slam on to the horizontal support and then falls into place. At that point any one that can lift off the horizontal bars of the tower can begin hooking on to us at the same time we lift.

Our structure is made out of 1.5" diameter tube with 0.083" wall thickness, we currently have vertical pole and have talk about having vertical lifter on us. Our only concern is the torque that would be applied to our vertical supports and whether or not it could handle it. With a 24" arm and a 150 lb robot the torque we would see on our vertical supports would be some where around 3600 in*lbs. We are going to test that in a controlled environment before trying it on the field.

I will try to do my best to get some action shot and maybe even some videos posted some time this week.

Re: Best 2010 Lifter
 

2337's lifter has a series of pins. When the lifter raises up one set of pins is pulled out of place releasing the lower supports, once the hooks connect (or more accurately swing past a certain point) it releases some pins out which is what lets the upper structure slide up and down on the support poles. The sound could also be the mass of the structure hitting the tower, there is a lot of mass moving quickly and all the bodies are hollow. Either way, it is a nice sound no?

To answer your next question; not as the system works now. One of the parents did some math and figured out that the load on the vertical supports exerted by 27/33 style lifters is ~2x what the structure can support. Realistically the vertical support beams don't support any of the robots hanging off of us it is only the upper pseudo tower that is supporting additional weight. This MAY change but I do not know.

3rd: Those poles are the same diameter as the tower so that if a hook works on the tower it will work on the pseudo tower.

Hope I answered your questions.

EDIT: Clinton beat me.

Re: Best 2010 Lifter
 

No doubt about it Teams 2337, 27 and 33 have the best designs when it comes to hanging. Team 2337 the NERDS have the best design to have others hang from them.

Re: Best 2010 Lifter
 

Maybe your opinion :P (I havent seen them so I can't say for sure)

... But I'd match teams 78 and 151 hanging systems up against just about anyones. Quick and effecient.

Re: Best 2010 Lifter
 

Some really good hangers at NJ that pop into my head: 25 (a very similar setup to 148, even though they've taken theirs off), 1672, 1676 (I may be biased but ours was one of the better ones there). 2016 and 2753 weren't too shabby either.

Re: Best 2010 Lifter
 

25 seemed to have problems with hanging in the eliminations at Jersey. It looked like their mechanism that slid them up the bar after rotating up failed to go up high enough.

Re: Best 2010 Lifter
 

In the matches I saw 25 play, I only saw them miss one hang which was when they ran out of time and missed by about 1/2" or so.

I think they hung in one of the finals matches against us but I'm not entirely sure.

Re: Best 2010 Lifter
 

During the very gentle playoff matches in nj (hehe) A bar bent that kept us from getting up all the way. We will have a much stronger one build for las vegas.

Re: Best 2010 Lifter
 

One of the other problems, maybe in the final match, was that the post on the inside of the bar (25'd be able to describe it better) wasn't flush up against it, and became a sort of hypotenuse, meaning they couldn't get up all the way.

Re: Best 2010 Lifter
 

We, along with 2016, are tied for most lifts in NJ. We coulda had more but had SO many problems in the elims, we didn't even get one hang in.

I didn't get a chance to see 2016's but heard it was good.

Re: Best 2010 Lifter
 

The best I have seen by far is team 78 at Manchester. their arm was fast and efficient and did not take away from the rest of the game. team 151 also lifted quite well. does anyone have a video of team 25. I have heard so much about them on cd but not seen any media.

Re: Best 2010 Lifter
 

At NJ 25 had an awesome hanger. 2016 and 2753 had two awesome telescoping arms that were really quite brilliant and we may have to replicate the idea in the future.

1717 who hasn't been seen by most because sandiego wasn't web casted has an amazingly fast and cool hanger
they hang at the end of this video:
http://www.youtube.com/watch?v=H-e7_Cyp8iA

Re: Best 2010 Lifter
 

...but we just had to, man. It's what we were born to do. :D

If I may brag a moment (because in six years I've never had a *robot* to truly brag about, even if I've had a team that is awesome), I believe that 22 hanging points puts us at the top of the ladder for week one...

But that said, 1717's lift is *freaking amazing*. I love it. It's the only one I've seen so far that might be faster than ours.

Well done, 1717, well done.

Re: Best 2010 Lifter
 

Our team currently cannot hang (which we might be changing) but i still only saw one team at kettering that i would feel comfortable attempting to suspend from and that was the 2337

Re: Best 2010 Lifter
 

25 hands down.

I will toot 11's horn about speedy hanging once I have video (we only hung once in NJ and didn't have it set to raise high enough)

Re: Best 2010 Lifter
 

78 had an impressive lift.

I'd have to say 126....but I'm a bit biased.

Re: Best 2010 Lifter
 

I feel like im biased too... but even though we haven't been to a regional, ours can release, grab, and hang in under 15 sec. im hoping that thursday this week i will actually be able to say on a competition field that it did that well:D

http://www.youtube.com/watch?v=ZHmRrZ9asEo

in this video, we climb in about ten seconds... and the motor was not turned all the way up (poor brent was a little slow with the controls :rolleyes: )

Re: Best 2010 Lifter
 

525's lifter was always fun to watch and was quite consistent. Once they got up onto the bump in the last 20 seconds it was basically a guarantee. Although it ended up dooming us in the 3rd finals match it was still my favorite. ;)

EDIT: After seeing the video of 1717's lift, I must say it is extremely impressive as well!

Re: Best 2010 Lifter
 

I posted some picture of our robot in the Suspension Thread:

Re: Best 2010 Lifter
 

I've heard murmurs of a 4 CIM hang.



:eek:

Re: Best 2010 Lifter
 

COOL!
Look what I found on Facebook.
Good view of both robots hanging in the last match.

Re: Best 2010 Lifter
 

Also, I've got to mention 2016 in here. They were our alliance partners in NJ and hung extremely well and could clear the platform by 8" or more. I'd watch out for them in Dallas.

Re: Best 2010 Lifter
 

I'm sure 254's robot is a great lifter. We've come to expect nothing less. However, this thread is about the best lifter, and I'm from Missouri, so show me. You're about 5 weeks too late for teasers.

It should have been obvious to anyone who's been around since 2004 that 254 would lift using their drive transmissions, but for those who are newer, now you know.

Re: Best 2010 Lifter
 

Sweet!

Thanks!

Re: Best 2010 Lifter
 

I wasn't talking about 254. Can I not compliment another team?

Re: Best 2010 Lifter
 

Our coach, Jack, wanted video of the last match in the worst way.
They are very proud of finally being able to hang.

Re: Best 2010 Lifter
 

I've seen said hang. Very impressive. Fastest I've seen so far.

Re: Best 2010 Lifter
 

How fast?

Re: Best 2010 Lifter
 

Those folks up north sure are crazy :rolleyes:

Re: Best 2010 Lifter
 

Faster than anything that was seen in week 1...by a lot.

Re: Best 2010 Lifter
 

So, under four seconds? Niiiiiiiice!

Re: Best 2010 Lifter
 

I've seen 2.5 second hangs in week 1.

Now, just look at 2004 and it's pretty obvious who these posters are talking about. They should be off the ground in a blink.

Re: Best 2010 Lifter
 

Chris and I timed it using the videos, it was like 16 or so inches in about 1.5 seconds, correct Chris?

Re: Best 2010 Lifter
 

Yup, and that's about as far as they'd need to pull with a straight hang. And they had drills rather than CIMs then right?

Re: Best 2010 Lifter
 

Sorta. They had 2 F-p, 2 Bosch drill motors, and 2 CIMs (+ some other less powerful motors). So they could have had drills or CIM's.

Re: Best 2010 Lifter
 

In my opinion the time it takes to hang (while important) doesn't seem to be as large of a factor as the time it takes to line up for a hang. This is one of the reasons I was for a vertical pole hanging robot from the beginning; if the front of your mechanism is shaped right you can just drive straight at the pole and be set to flip yourself up. If you pull power off your drivetrain to do it, and have the hanging routine sensor-activated to begin as soon as you are latched on, you could hold off of going to hang until the last few seconds of the match. (I don't know if anyone will do this, but it's fun to dream)


That said, 219 has one of my favorite lifting mechanisms so far... they flip upsidedown onto the platform. I only caught it once during the webcast, if anyone has more video I'd love to see it.

Re: Best 2010 Lifter
 

The only thing Chris and I wondered about was how much the Poof 04 bot swung around while it was being pulled up, it seemed a bit dangerous. I'm sure they thought about how to stabilize the bot though for Breakaway, if they're using the same method that is.

Although I'm trying to wonder why it wouldn't be used, it was mad fast. For anyone who doesn't know what Chris and I are referring to: http://www.youtube.com/watch?v=6ZuUdaCLZzg

Re: Best 2010 Lifter
 

still not as fast as a servo twitching :)

Re: Best 2010 Lifter
 

Wow.

That's an awesome find Stogi. 254's '04 bot is still one of my Favorite robots to date.

Re: Best 2010 Lifter
 

I guess the cat's out of the bag now... If anyone has seen 1114 at Pittsburgh, they are hanging with 4 CIMs and man is it FASSSST.

Re: Best 2010 Lifter
 

So its 4 CIMs eh?
I must agree, this is the best I have seen to date.

I wonder what a similar design using stored energy to articulate would be like. Time is never a factor then... as long as you release for 'curl' before t=0.


Kudos 1114, your machine in all aspects is amazing again.

Re: Best 2010 Lifter
 

Yeah, i just watched their last match. I saw them kick a ball and hang in all of like 5 seconds. Amazing, quick machine.

Re: Best 2010 Lifter
 

Very true. I was watching Pittsburg's last 3 matches and got to see 1114 line itself up and get a bonus 2 points in what was probably the last 4 seconds of the match. I didn't expect it would be that fast, so I kind of missed what it actually did. :(
