Best/Favorite Ramp Design
 

With all of the talk about Cheesecakes and Cheesecaking - what is your most favorite Ramp Design so far - Static or otherwise ? I am talking about the "Robots" that are made purely to interface with the Chute at the Human Player Station on the playing field side to control the totes as they are coming out from the chute.

Re: Best/Favorite Ramp Design
 

My favorite so far - besides Robin the stacker - is the one that Team #1815 deployed at the Greater Toronto Regional. It worked great and no-fuss no-muss.

Please include a picture if possible.

I haven't seen any ramps in play yet but there was a certain team (I can't remember the number) from Israel that had a conveyor-belt type of ramp that seemed to work very well.

You're probably thinking of 1657, Hamosad: https://www.youtube.com/watch?v=CjfZ-jpPCWA

Re: Best/Favorite Ramp Design
 

Yeah, that's the team I was thinking of. Thanks for the link.

Re: Best/Favorite Ramp Design
 

Going a bit off of best ramp design. What materials do you think make the best tether? I have seen everything from airplane cable to fishing line.

I think my personal favorite has to be whatever 1023 used in Woodhaven. It seems to lay pretty flat, and it is REALLY visible.

There's a huge thread I made on ramps check it out for that.

Is it "#teamtether club " ?

Re: Best/Favorite Ramp Design
 

Anybody seen a team just have what would basically be two robins?

Re: Best/Favorite Ramp Design
 

This is probably my favorite robot idea this year. It looks like they only got this one chance to compete?? Does anyone have video of them in action?


If there was a reset, I'd be willing to bet many elite teams would iterate on stretchy and fetchy. Imagine if the main part of the bot (lifty?) could lift with the speed of 1114 :ahh:

I would imagine a lot of teams could also fit a stretchy into their witholding allowance. The teams that can make good stacks but struggle with moving them around could just build them all in place...

Re: Best/Favorite Ramp Design
 

I personally like 1671's ramp design. But I may be slightly biased.:D

Re: Best/Favorite Ramp Design
 

What about stairs?;) I saw Simbotics and Op using an upsidedown tote turned sideways against the wall as step for the tote chute. Maybe not as smooth as a real ramp but it works and it doesn't require a tether. I would imagine they could shove it to the step and set a 5 stack on it in the last second.

Re: Best/Favorite Ramp Design
 

just wondering why dont they need a tether

Re: Best/Favorite Ramp Design
 

So can we make #teamramp a club? :)

Re: Best/Favorite Ramp Design
 

Because it's just a regular tote from the actual field. Very ingenious.

Re: Best/Favorite Ramp Design
 

696 did something similar with a yellow tote.

The reason none of those three need a tether is because they don't bring the tote onto the field. It's already there, they just repurpose it for use as a tote ramp.

Re: Best/Favorite Ramp Design
 

And they can only use the big ramps they bring on practice day. At their prior events they've tethered these ramps to partners for official matches.

It's just like 3 teams running 2 ball autos in practice matches.

Re: Best/Favorite Ramp Design
 

so they have to move it over there mid match or can it be leagly placed there pre match

Re: Best/Favorite Ramp Design
 

I think you know the answer to that.

Re: Best/Favorite Ramp Design
 

dont be rude, based on that response Im guessing they move it but $@#$@#$@#$@# that was snarky

Re: Best/Favorite Ramp Design
 

You were implying that you hadn't read the manual. I realize that not everybody memorizes it every year--I don't, I go for the general gist and where to find stuff quickly, and on the field I use a cheat sheet--but after watching 3 weeks of regionals and spending 6 weeks building the robot, something along the lines of "how do you not know that" (even without the previously-mentioned manual reading) might actually be appropriate. "Ask a stupid question..." and all that. When a drive team member asked me if yellow totes counted on the scoring platforms (during a practice day), and then admitted to not having read the manual...Well, I did answer the question, but I also gave him one of those looks that is supposed to mean "I can't believe my ears" or something along those lines.



To actually answer the question: If they place it there pre-match, it gets moved back to wherever it came from before the match starts. So they have to grab it mid-match.

I've read the manual quite a few times but I was wondering

Re: Best/Favorite Ramp Design
 

Obligatory "My ramp is my favorite!" comment.

I believe we just used some rope a mentor had laying around. I think it's just white nylon rope. He used it on his boat or something.

Re: Best/Favorite Ramp Design
 

Because...the internet....





and cheesecake/corndogs/pizza

Re: Best/Favorite Ramp Design
 

We see team 314: The megatron Oracles aka BIGMO, using a ramp to feed from the chute, and obviously its working

Yeah, well it saved us a little bit of time.... Though the biggest improvement was our can holder up top....

Re: Best/Favorite Ramp Design
 

We went with a ramp this week, and I don't think it speed us up to significantly, but it eliminated a bunch of failure points we had while stacking from the chute on top of tote. Our design did not have any features to control the second tote, so we were at the mercy of our awesome human player to get the speed and location right to set on top of the tote on the floor.

He was very good at this task, but not 100%. When it messed up, it was ugly, and we put up scores of 14, 40, and a semifinal 48 which all most killed us. . .
Result at Waterford, two blue banners.

This week at West Michigan, we added the ramp.
Lowest score of the day was a 65, then 80 and 85.
Result West Michigan, one blue banner.

So for us, the result was not a huge speed increase, but eliminating some failure points, and making us more consistent.

SPIRAL RAMP for Tote Delivery
watch here
https://www.youtube.com/watch?v=kS2DHfNJ6_U

We built a ramp that carried the totes all the way to the scoring platform after we had bagged and tagged. It didn't fit within our withholding allowance so we had to fabricate it at our regional ( Smoky Mountain FRC Regional). During practice the officials had us move our battery inside our frame perimeter which threw 14 lbs of our ballast forward. It was a legitimate safety concern, but it crippled us on carrying a load. we realized to late that we could have built a carbon fiber box around our battery and salvaged using the spiral ramp.

We weren't designed to use this ramp since it was an after thought. I hope someone with a slide, mecnum or swerve drive can pick it up and use it at championships. I can send the CAD work and material list if needed.
