Vertical Pipe Hanging
 

Hey, I'm from Team Rush. If you didn't know, our robot hangs itself by grabbing onto the vertical pipe and flipping over itself. I only know of the following teams that do this:

27 - Team RUSH
33 - Killer Bees
148 - Robowranglers
217 - Thunder Chickens
1114 - Simbotics


Am i missing anybody?

Re: Vertical Pipe Hanging
 

217 and 148 removed theirs to improve their driving.

1633 drives up the pole. I think 359 has the ability but doesn't use it.

Re: Vertical Pipe Hanging
 

1902
179

and we drive up the pole, but we dont flip ourselves over. didn't know how specific you wanted

Re: Vertical Pipe Hanging
 

Add 254 and 1280. 254 uses a two-jointed arm that folds entirely into their frame. Because of this, it's the only robot I've seen that hangs this way AND can go through the tunnel.

EDIT: and 1717. I haven't seen theirs up close, just on the SD webcast, but it appears to drive up the pole. And 78 definitely drives up the pole.

Re: Vertical Pipe Hanging
 

Team 1718 hangs on the vertical in 6.8 seconds

Re: Vertical Pipe Hanging
 

2791, 2775, 1625, 2079

Re: Vertical Pipe Hanging
 

REALLY NOW! Thats really surprising! Can they go under the tunnel now?

Re: Vertical Pipe Hanging
 

It definitely is one of the faster ways to hang, from what I've seen so far. Perhaps my favorite aspect of the idea is that it makes it easy for another robot with the more popular way of hanging to hang on the horizontal bar.

To answer your question, I do not know of any other team that may be able to hang off the vertical bar.

Re: Vertical Pipe Hanging
 

2557

Re: Vertical Pipe Hanging
 

doesn't appear they can...

Re: Vertical Pipe Hanging
 

I don't know. All I know is that some time after their videos came out, someone from one of those teams came out and said that they were removing their hangers to use the weight to make improvements in the drivetrain.

Re: Vertical Pipe Hanging
 

Teams 25, 75 and 1403 all hang from the side bars.

Re: Vertical Pipe Hanging
 

Team 343 has one of the more unique designs for hanging this year (in my humble opinion). They latch onto the pole and drive up it, instead of flipping up.

It looks quite awesome. Can't wait to see it for myself in person this weekend.

Re: Vertical Pipe Hanging
 

As of the cass tech district we played them in, they could not go under the tunnel. It is very unlikely that they can now due to the height of the robot at cass tech. but if they do, kudos to them.

Re: Vertical Pipe Hanging
 

903 can do it. But ya 217 / 148 ditched them in favor of a lower CoG and strengthening their chassis.

I wonder if they regret it or are happy with the overall improvments. (in that one video way back when it did look like they were a little unstable going over the bump, if fact I'm pretty sure they only went over it backwards.)

Re: Vertical Pipe Hanging
 

78 hangs from the side bar, but doesn't flip.

Re: Vertical Pipe Hanging
 

At Cass Tech they seemed to be doing just fine with the bumps and handeling them.

Re: Vertical Pipe Hanging
 

This weekend our hangers gona be much faster (and more colorful). YAAY:D

PS. to RUSH, I think this makes us arch rivals, In a good kind of way;)

Re: Vertical Pipe Hanging
 

I'd agree they are very nimble while going over the bump now. In fact, I'm not even sure they couldn't go over forwards before their arm was taken off, Its just that it wasn't shown in the video.

Re: Vertical Pipe Hanging
 

When pit scouting, someone from 910 said they could hang from the vertical bar and drive up it. I NEVER saw this happen however, so I won't stay they can for sure. Did any else hear that and can confirm/deny this data?

Re: Vertical Pipe Hanging
 

Well, how recent was this? at Kettering they had nothing of the sort on their robot, although I wouldn't be suprised if they have built something since and are planning on using it this weekend.

Re: Vertical Pipe Hanging
 

It had to be at kettering becaue that is the only district they have competed in and i was at kettering and i saw no sign that hey could hang with their robot.

Re: Vertical Pipe Hanging
 

It was at Kettering they they said that. I'm going to double check it at Troy and confirm or deny this.

Re: Vertical Pipe Hanging
 

They could have been kidding, like when people tell you they have a billion wheels on their robot and it can fly. Sometimes some sarcastic team members will tell you this if you ask them something that's obviously not true (asking a kitbot if they can suspend robots, for example)

Re: Vertical Pipe Hanging
 

Our robot also has a double jointed arm that enables us to hang vertically and still go through the tunnel.

Re: Vertical Pipe Hanging
 

I'm sure they weren't kidding. I talked to one of their mentors also (although that doesn't make a difference). I also can only find one picture, which is no help at all. http://www.flickr.com/photos/daniele...7623582837940/

From what I can see, it lacks any sort of hanging mechanism...

Re: Vertical Pipe Hanging
 

910 was working on the whole drive up the pole thing and the parts were on at kettering but not working. They may be ditching that idea to use the weight some place else.

Re: Vertical Pipe Hanging
 

1218 hangs form one of the vertical poles

Re: Vertical Pipe Hanging
 

Yes we drive up the pole, worked flawlessly during elims at GSR

Re: Vertical Pipe Hanging
 

Thank you! :yikes:

Re: Vertical Pipe Hanging
 

Awesome! That makes two (three if you count 968, although I can't confirm that one for sure...)

Re: Vertical Pipe Hanging
 

Team 226 is working on it. We had to gear down to get enough torque but at that point we had already been through several disasters with out original hanger that we didn't want to try...one of our mentors did it anyways. We are currently debating whether or not to mount it due to the effects it may have on our bumpability*.

*how fast and efficiently you can go over the bump

Re: Vertical Pipe Hanging
 

Correction: Team 75 hangs from the horizontal top bar, as witnessed here: http://www.chiefdelphi.com/media/photos/35278

Add 612 to the list.

Re: Vertical Pipe Hanging
 

Maybe I'm in the wrong thread here, but does anyone have a video to show of a robot "driving" up a pole. I think I know what your talking about, but need to see it in action.

BTW: In a match at SVR, 254 was scoring a ball with 10 seconds left, then drove to the tower, lined up and hung with 4 seconds still left in the match. This was on Friday at their first comp. I bet they will get this manuever (depending on defense of course) down to just a few seconds. VERY FAST!!

Re: Vertical Pipe Hanging
 

126 folds up, 78 rolls up

Re: Vertical Pipe Hanging
 

video of ours before ship: http://www.youtube.com/watch?v=ZHmRrZ9asEo

Re: Vertical Pipe Hanging
 

Re: Vertical Pipe Hanging
 

1391 does the 'strong man' vertical pipe hang

Re: Vertical Pipe Hanging
 

add 135 to the list...

Re: Vertical Pipe Hanging
 

Look at this video starting at 2:28 to see 78 drive up the side pole. http://www.youtube.com/watch?v=yc4mw8YvBLw

Re: Vertical Pipe Hanging
 

2751 and 1319... two that i forgot :p

Re: Vertical Pipe Hanging
 

We are also able to go throught the tunnel and hang from the vertical post.

Re: Vertical Pipe Hanging
 

You can also add ...
3371 - Thunderbolts

Re: Vertical Pipe Hanging
 

Yep, 1717 latches on to the pole then uses a gas shock to push off the platform. One of the cooler hanger mechanisms I've seen this year.

Re: Vertical Pipe Hanging
 

Now the next goal.

Suspending from a robot on the vertical bar.
Now that would be impressive:ahh:

I know that 33 is capable of holding up another robot without breaking, but is going for more of a quick hang at the very end. Anyone else able to withstand that kind of forces well hanging or have considered it?

Re: Vertical Pipe Hanging
 

Actually, make it four. 973's robot is very much like 254's, with the two-jointed arm design. It wasn't fully functional at SVR. I don't know if they ever used it in a macth, but I saw them elevated on the practice field right before our last qual match (with them, in which they did not hang). But I bet they'll have it working for Vegas!

Re: Vertical Pipe Hanging
 

we can go under the tunnel as well

Re: Vertical Pipe Hanging
 

Then I wonder how it helped them with shooting...

Re: Vertical Pipe Hanging
 

Plagued by lots of electrical problems, we never got the arm to hang in a match. It's mechanically sound and worked on the practice field multiple times, and we will be hanging at vegas.

Re: Vertical Pipe Hanging
 

One of my friends is on that team. They said that their robot has the capability to, once they get the mechanism finished. It works on their practice bot.

Re: Vertical Pipe Hanging
 

Haha, maybe, or destined alliance partners. Scorpio-bot team (I think both of our robots look like scorpions)

Re: Vertical Pipe Hanging
 

You cant see it in the picture, but they cut a hole in the back of their rear polycarb package protection wall and (I believe, correct me if i'm wrong) made an extendable arm to put there.

Re: Vertical Pipe Hanging
 

Wow! Very impressive. The more I hear about 343's lifter, the more I like it. It sounds like you guys accomplished so much with such a simple mechanism. Great job!

Re: Vertical Pipe Hanging
 

Agreed. There is so much torque associated with our robot we must be very careful. (over 450 ft-lbs) Theres lots of value in a simple, elegant design. Nice job 343.

Re: Vertical Pipe Hanging
 

thanks so much for the kind words!:D i was very happy with the success of the design (partly because it was my senior project, and partly because im the driver). it is defenitly one of the more simple, yet very effective designs that we have come up with in our 11 years. we were wondering at first whether it was worth it to go through with a plan we didn't know would work, but we are glad we did.

so thanks again guys, it means a lot. makes me feel warm and fuzzy :D

Re: Vertical Pipe Hanging
 

Good, you should be proud. It's a great design! I hope you win a design award and it makes you feel even fuzzier! :D

Re: Vertical Pipe Hanging
 

Hey rush guys, speaking of your arm, how do you power it? I assume either 1 FP or 1 CIM, but I don't know how you are gearing it. As a comparison to yours, we have a CIM geared 12:1 through a DeWalt transmission with backdrive pins, going into part of a 12.5:1 toughbox with 16tooth-72tooth chain. I also noticed two other things about your arm: it lacks a foot and its much longer than ours. I assume the lack of a foot makes little functional difference, but is the long arm to prevent backdriving when power is cut (so the cg is past the shoulder joint, causing the robot to fall into the pole)?


450 ft-lbs you say? Stall or running? We've got over 600 ft-lbs theoretically at stall, assuming no losses. We have only ever hit stall when the analog module ejected from the cRio causing the arm to kill itself (almost).

Re: Vertical Pipe Hanging
 

*in a whisper* (we already did :) )

Re: Vertical Pipe Hanging
 

Oops. Well, go win another one! :p

Re: Vertical Pipe Hanging
 

1633 can also climb the vertical pole.

Re: Vertical Pipe Hanging
 

58, 973 (i recall them having basically the same thing as 254)

Re: Vertical Pipe Hanging
 

This has been on my mind latley and i guess this is the right thread for it. How long does it take for your vertical hangers to get all the way up?
1718 takes a little less than 7 seconds

Re: Vertical Pipe Hanging
 

after latch on? or latch on and lift total
after latch on we're about .01 seconds :p
and latch on is just slamming the arm into the bar pretty much

Re: Vertical Pipe Hanging
 

5 second pull up, but I don't know if the motor was running full speed or not.

Re: Vertical Pipe Hanging
 

Maybe thier robot can take it but can the goal? It might snap that bar right in half!

Re: Vertical Pipe Hanging
 

I'm guessing the GDC planned for that when their field designers went to work on the tower. I doubt that that bar is going to fail under 2 robots hanging off the same points. MAYBE 3, assuming one of them has very, very sharp saw-toothed hooks and swings a bit to saw into the bar a bit.

Re: Vertical Pipe Hanging
 

In one match at Wayne State, team 27's robot grabbed onto the bar incorrectly and when it tried to hang, it indented the bar so much that it had to be replaced by one from the practice field. :eek: So ONE robot has caused the bar to fail, and 27 doesn't even have an active grabbing mechanism on its end effector - it simply snaps on.

Re: Vertical Pipe Hanging
 

Team 27 also has about 2 inches of their robot actully touching contacting the bar while lifting. 33 has closer to 8 this = much less chance of denting the pole. However, even then it still might be a problem, but I don't quite understand what you mean by grabbing the the bar wrong. On our robot its either on or not on in which case it won't lift us and we'll have to re-clamp.

Re: Vertical Pipe Hanging
 

If 27 did as you said, were there any repercussions? A warning perhaps or even a penalty?

Re: Vertical Pipe Hanging
 

Team 148 was still a monster competitor this year, even without the hanging mech. A definite congrats to them on 1st at Lone Star.

Re: Vertical Pipe Hanging
 

The reason we latched onto the pole "incorrectly" is because there was some deformation to begin with. After reviewing the video of the match, there is a noticeable "dent" in the pipe before we even touch it, thus leaving the pipe not true to its diameter, making it impossible for our latching mechanism to fully click on.

That being said, we did leave 2 smaller indents in the pipe where the "fingers" of our grabber were pushed in with an amount of point loading that they and the pipe would not see under normal operating conditions of our grabber.

So yes, we did mark the pipe, but the damage that caused the pipe to be replaced wasn't necessarily all our fault.


John, we were not given a penalty, but since the damage to the pipe was brought to the attention of those managing the field right after our attempted hang, we were given a warning that if it was discovered we damaged the pipe from that point on that we would have to modify our mechanism as per the rules regarding field damage.

I can tell you that Team RUSH never left a mark on the pipe Saturday, which myself and my fellow drive team members inspected after each round.

Re: Vertical Pipe Hanging
 

There should be another robot to add to this list after States...

Re: Vertical Pipe Hanging
 

And hopefully one in time for state... don't look at me

Re: Vertical Pipe Hanging
 

from what I hear 2056 does the 78 style drive up the pole hanging. Can't wait to see it in action.

Re: Vertical Pipe Hanging
 

In an even quieter whisper... We did that too!

Re: Vertical Pipe Hanging
 

You can add 968 to the list. (254's twin).

Re: Vertical Pipe Hanging
 

Another team to add to the list is 3223, a rookie from Central Kitsap High School in Washington.

Re: Vertical Pipe Hanging
 

Teams 84 and 1391 were also able to hang from the vertical pipe at the Philly regional.

Re: Vertical Pipe Hanging
 

You can add 1511 to the list as well.

Now if only the potentiometer on the winch didn't break during the finals :(

Re: Vertical Pipe Hanging
 

Add 2090 to the list.
At San Diego and Arizona, about 30% of the teams didn't get any hang points. At Hawaii, only 2 out of 28 didn't have any hang points.

Re: Vertical Pipe Hanging
 

Add 1388 to this list, we could consistently drive up the pole and go under tunnels. If we latched on and started going up before the last 10 seconds we would get the bonus. Hooray for FP's and planetary gearboxes. :]

this is how you hang

Re: Vertical Pipe Hanging
 

1468 of Hicksville uses the vertical bar as well. Kind of like a one-handed pullup

Re: Vertical Pipe Hanging
 

I guess this thread was started to keep track of teams that utilized the innovative strategy of vertical pole hanging. However it seems that the strategy was not as innovative as we'd expected and it seems the list has grown exceptionally long to the point no one's keeping track anymore. While I am impressed with the number of teams doing this, at this rate we might as well start on the list of teams that can kick :p because that list will be finished around the same time this one is.

Re: Vertical Pipe Hanging
 

84 also latches and flips on the vertical pipe. I think there may have been a few others at Philly that haven't been mentioned yet.

Re: Vertical Pipe Hanging
 

1197 latches onto the bar and pulls itself up using a four-bar linkage system. We didn't get it working until late Friday at Los Angeles, but it gets the robot up in 6-8 seconds.

Once we got it working, that is.

Re: Vertical Pipe Hanging
 

We added one during championships but we only got it to hang once because every other time we either didn't have enough time or something wasn't working like it should.
