I know some have think about pneumatics but then It comes to having a "light" robot.. anyone has thought about something?

Re: Climbing Mechanism Ideas
 

Seeing 3 robots all score the 30 point bonus on one tower will be like seeing the Loch Ness Monster this season.

(Seeing one climb that high in about 4 seconds after the buzzer on the other hand...)

:rolleyes:

There ya go Paul!

Where exactly is the auto zone? My team would like know exactly where on the field your robot can go up to 84 inches?

Re: Climbing Mechanism Ideas
 

Your colored carpet and i believe feeding station, not sure about the latter though

Re: Climbing Mechanism Ideas
 

The auto zones are the areas marked out but the long pieces of red and blue tape that cross the fields on the side of the pyramids closest to the center of the field. If you look at the field drawings in the manual, look for the biggest pieces of colored tape. Whenever you are contacting carpet within the zone or are touching the pyramid, you can go to 84".

Look what they did a few years back in FTC. Look familar?

Re: Climbing Mechanism Ideas
 

Yeah, that was VEX round up. The biggest difference between then and now is that in round up, you could latch on to the top and pull yourself all the way up which is, unfortunately, illegal in Ultimate Ascent.

Re: Climbing Mechanism Ideas
 

That's true , but only grabbing the second rung with s similar technique would get you 10 points.

Re: Climbing Mechanism Ideas
 

Ok it took awhile to find, but here is a climbing robot that could climb our pyramid legally

Re: Climbing Mechanism Ideas
 

Need idea, but that robot is touching more than 2 levels at a time, if you consider each rung of the ladder a level.

Re: Climbing Mechanism Ideas
 

Not sure if this is only an allusion to 2010 or if we should all be very, very afraid...
Either way I can't wait to see what you guys come up with in terms of climbing this thing, if you can do it in 4 seconds, that will be a feat of engineering itself, before or after the bell!

Re: Climbing Mechanism Ideas
 

That's one of the most complicated elements of this climb. It cannot be accomplished using a method that is intuitive to how a human would complete the task (aside from jumping up the levels but I don't think most people will feel comfortable with a 100-something lb robot jumping around 5'-8' in the air).

Noticeably absent in this year’s competition is the lack of overt scoring opportunities for cooper-tition. I thought this was strange considering FIRST’s ever-present focus on gracious professionalism and collaboration. After three days of mulling over any solution for robo-soloing the tower completely above the first rung, it dawned on me that the design of the tower requires a collaborative approach and that’s why the number of points that can be achieved or so high in comparison to tossing a Frisbee. Team efforts receive more points than those of individuals. Really – They always have.

Although Frisbees are certainly involved in play, they play a minor role in scoring and are probably (forgive me) a red herring. I believe this contest is really a test of team’s abilities to work together to scale that structure. That may be the reason why an individual robot can’t make contact with more than two rungs at a time and can only skip the first rung. It seems that we’re being setup to work together and it’s that feature that may in fact be designed into the game as the desired outcome by the game’s designers.

I think that this must be the rationale behind the game hint we received from the GDC in the form of a still-shot of Rick Ashley music video, “Never Gonna Give You Up.” Here’s the refrain.

Never gonna give you up
Never gonna let you down
Never gonna run around and desert you

The good news… This makes climbing the pyramid much easier if teams work together. Now – How do you capture a Frisbee off the floor.

Re: Climbing Mechanism Ideas
 

Yes, I've thought about this multiple ways.

My immediate thought after kickoff was to scoot under and send a grappling hook up to level 3, and "ride the elevator up". Until I read the rules, and realized you have to touch each level in order. Then I thought, climbing from the inside might be easier, if you depend on gravity to lean you into the climb. But after wrestling with it a bit, it would seem like it might be easier to climb from the outside, where the pyramid is somewhat underneath you.

Has anyone give thought to building a ramp bot to assist others in climbing? They show one in the video, but I'm very unclear on how that would affect the climbing sequence rule.

Re: Climbing Mechanism Ideas
 

The way I read the rules, I would say u r correct
