It does look a bit like it is just held up by a piece of 80/20 clamped on. As if they were just trying to show what the robot will look like when they do climb. Then again, the 80/20 might be under the rung (not supporting the robot). It is kind of hard to tell though.

How fast is it?
How fast is it?
It took about two minutes today (but we stopped on each level and paused for a bit). Hopefully we'll get it down to about a minute soon.
I believe the polycarb is the device they use to reach up to the next level and then ratchet themselves up with the red strap to grab with the robot. Then they unwind the ratchet to reach up to the next level.
I like it a lot.

Would you be opposed to a small group of Bloomington students coming over to see how you guys did it? =O

Do you realize how many people are not going to sleep tonight? :).
Here's my guess on how it works...
Could it work this way? Polycarbonate is up with a cable or cables attached about 3 inches from the end. Drive under, pull up to pyramid cable towards pyramid. Start pulling the cable down and the polycarbonate goes on the other side of the bar. An angle is formed between the polycarbonate and the cable where the horizontal bar on the pyramid rests. As you wind up the bot is lifted. Get to a point where you rotate out or over the bar, two hooks that you hang from (or the bot goes up and over and hangs from). Release poly carbonate, then pull yourself up to the next level.
We'll know for sure if they post a video.

It doesn't look like it will be an issue, but be careful to take into account the pyramid goal, it looks as if your robot is protruding into it in the picture. I'm not quite sure though.

Does anyone have the original photo(s) to post to an image host or CD?

I'm a little skeptical. Would they REALLY have climbed with a robot with that many loose wires hanging out of the bottom? Maybe...

I see the same thing, it looks as though the arc of the polycarb is within the pyramid goal. That could be a problem i would take consideration of it.

They are about 8" higher than they need to be to clear the bar. So they can just not go up as far. I like the simplicity of the design. Good work. I look forward to seeing your bot in Duluth.

I think she meant that she's going to take a video of the next test, presumably after the team meets today. I'm dying to see it though.
It looks like the level three rung of the pyramid is going through the frame of your robot, behind the C-Clamp and in front of the green rope (which I assume is just there for belaying purposes).
Looking forward to the video.

I was thinking about it today and was going to recommend that to them, but i guess you beat me to it :D .

I'm assuming this is a fake, and they just "nailed" it up on the third rung...I'm going to stop wasting time looking for the video :/

It would have been nice if the OP was clearer that this was a joke. I'm sorry, but it is clear that his wasn't a legit 30pt climb.
If so, that's pretty annoying. I wouldn't mind it it was just the photo (which is involves a manual C-clamp), but she said literally 5 minutes later (post 7 (http://www.chiefdelphi.com/forums/showthread.php?p=1223640#post1223640)) that she'd make a video. That's basically the opposite of making it clear that it's a joke. :\

This. Plus maybe her team said "Wait, we don't want to reveal our climbing stuff yet, so don't post it!"
Just wish the OP would come back and give us a status update
Instead of questioning and asking for vids, take a close look at the pic and learn.
I found the winch mechanism, bent lexan, etc educational and inspiring.... looks like a test/proof of concept that will work.
Clamp/extrusion is below the bar, you can see the shadow through the knot.

Personally, there's one component in particular that could be of significant value to us, particularly if they'd had tested success with it. I'm looking into it now. The question isn't how they intend it to work, just how far it's tested.

My sister posted this she showed me the video and this actually works. She has the video but I don't plus we go to different schools so we are on different teams. It does work but I dont know when she is going to put it up.

Hey now, some of us have made bets on when the first full 30 point climb video will be released. Here is to hoping it takes them another 11 days to post the video... :)

Well, if we stick to our schedule and finish the robot on time, we'll have our first 30 point video posted in 9 days :D So, who has Feb 9th in your little betting pool?

What the picture shows is only 20 poins. Thwhole robot has to be over the third bar

No, the whole robot has to be over the 2nd bar for 30 points.

That is incorrect. Zone 3 is above the second bar. This is a 30 point hang(assuming all other climbing rules were followed).

We got a lot of our final climber design finished last night in CAD and expect to be machining parts of it this weekend. Our current plan has us climbing next week.
At this point in the build, it's pretty much too late for anyone to copy our design so it's less a concern of secrecy and more one of embarrassment. Every time we think we have it perfect, we run into another issue and it's driving us crazy. The concept is the same one we've been using since the first day of the season, but the actual implementation of that idea has been incredibly complicated.

Congrats on the first 30 point climb video posted ever!
It appears that you need to articulate your center of gravity to do this hang. How are you planning to achieve that without someone holding it?

03-02-2013, 18:13
Nice! Glad to see it's not vaporware!
Wow. Amazing concept. I really hope that you can alleviate some of these difficulties you have, because if you do then you will really have a great robot (not that you need me to tell you).

Congrats! That's awesome.
Nicely done! Is it all human controlled or is it "automatic" climbing?
First of all - Congratulations!
This feat is a huge accomplishment. The 30 point climb is possibly the hardest challenge FIRST has ever thrown at FRC teams. I know there is still an amount of human "assistance" provided in the video's hang attempt, and it was not at competition speed, but to get even this far is a big deal.
Secondly - Thank you!
Whether it was your intention or not, your video provides a ton of useful insight for teams trying to perfect their own climbing mechanisms. You can clearly see there are many many little details that your team has taken into account to get the robot's centre of gravity to behave nicely as you climb, as well as the path of the hooks as they both extend upward and retract. The lower hook placement is critical as well.
Well done! And good luck in the upcoming season!

Im pretty sure the people holding the ropes and such are just there to keep the robot from falling; it's probably one of their first climbs, so they're being cautious.
Great video, interesting climb idea!

This is fantastic! Congratulations!
However, seeing an actual robot climbing from the inside, and seeing how little space is left in the top level for other 30pt bots is making me nervous. I guess alliances will just have to compromise and have some bots on the 3rd level and some on the 2nd?
How long is that video? 2 minutes? Hmmm...

Unless some bots can climb the outside

Great job guys looking foward to seeing you do that now with bumpers on.
Very innovative!
How about putting the bottom latch points as two
on the outside edges, just on either side of the Lexan?
Congratulations, and my apologies for any doubts I had earlier.
i dont think that pipping frame is 1" 1/2 OD if im seeing that right

I second this. Great Job!

The video is two minutes, but they do take short breaks in between. If they just speed up the process a little bit, I could definitely see them being able to both score a few disks and climb to the top during a match.
Amazing job, congrats on being the first to show the world that you can pull off such an incredibly challenging feat.

Can I ask what difficulties you see with adding bumpers? It looks to me like the mechanism is on top of the bot and this wouldn't be a problem.

Can I ask what difficulties you see with adding bumpers? It looks to me like the mechanism is on top of the bot and this wouldn't be a problem.As they're lifting with the lexan bit, the lower frame comes very close to the lower rung. I think the concern is that the bumper will catch on the rung, and the robot won't necessarily swing back to clear the bumper. They could solve this with a couple of bars that swing down over the bumpers at the beginning of the match to make the rung ride over the bumpers.
Also, they're going to be a tight fit inside that upper rung with bumpers on. If they don't line up right at the start of the lift, they're going to be stuck with a 20-point lift.

My favorite part of this implementation is the lexan sheet to deliver the hooks up. That's simple and effective. Great work guys!

I see what he was talking about now. It doesn't seem so bad, I think at worst it would slide against the rung and swing the bot back on the hooks a bit, since the frame passes the rung well before the lift is completed. I don't think any special mechanism would be necessary to prevent catching, just being smart about what they put on the front of the robot. Also, it looks like the guy behind the bot is pushing it forward a little, so it's coming closer to the bar than it would by itself.

or pick a robot that climbs the outside;)
This may just make our team's season. Our team has been struggling with this exact idea. Many students saw the video and were greatly inspired.
Think you can do it in 12 seconds? We do.

At the beginning of the season I challenged my students to climb in less than 10 seconds... I hope their design meets that challenge. But even if it doesn't, I know we have a great design.
With any luck, we'll be bolting the electrical board on my this weekend and start doing some real testing!
