BTW stretchy works fully automatically, we have a driver only for emergencies

Re: Stretchy and Fetchy-1657 robot reveal
 

You guys make me proud :)

Re: Stretchy and Fetchy-1657 robot reveal
 

I love the conveyor belt system. Great robot!

How does the bin collection device work? One side looks like a fishing hook and the other looks like a tethered robot to me.

Good luck at the regional!

Re: Stretchy and Fetchy-1657 robot reveal
 

So cool! I love the little mini bot pushing in the RC's at 1:50! I was really hoping to see some conveyor bots!

Re: Stretchy and Fetchy-1657 robot reveal
 

Awesome

Re: Stretchy and Fetchy-1657 robot reveal
 

Beautiful solution.

Re: Stretchy and Fetchy-1657 robot reveal
 

Does that have wheels? More importantly, does it even need wheels?

Re: Stretchy and Fetchy-1657 robot reveal
 

It's the factory! I love it, was really hoping to see someone pull this off. Great job, great robot

Re: Stretchy and Fetchy-1657 robot reveal
 

Wow! Really nice job.

Re: Stretchy and Fetchy-1657 robot reveal
 

Wow. That's incredible. Phenomenal work.

Re: Stretchy and Fetchy-1657 robot reveal
 

Nice work guys! What a unique and awesome system...

Re: Stretchy and Fetchy-1657 robot reveal
 

I think it's my favorite bot so far. :)

Looks great, although I wish the video had mo re shots of Fetchy doing its job.

Re: Stretchy and Fetchy-1657 robot reveal
 

the fishing hook is for the autonomous bin, there's a small lift that the tethered bot (Fetchy) pushes a bin onto.

Nope and nope :)

Hehe that'ss actually how the kids called this idea while brainstorming at the shop - the factory :)

Re: Stretchy and Fetchy-1657 robot reveal
 

Thanks for doing my job

Re: Stretchy and Fetchy-1657 robot reveal
 

That is a pretty slick solution strategy. Amazing job, guys!

Re: Stretchy and Fetchy-1657 robot reveal
 

So does the robot drive over to its final spot in auto?

Re: Stretchy and Fetchy-1657 robot reveal
 

Are you confident that you can start with your robot in that position? My concern is that you are in the autozone at the beginning of the match.

Re: Stretchy and Fetchy-1657 robot reveal
 

Thats what I was thinking.

Re: Stretchy and Fetchy-1657 robot reveal
 

Looks familiar;

All joking aside, this is a very cool concept. Very curious to see how it plays out.

Re: Stretchy and Fetchy-1657 robot reveal
 

Amazing awesome.

Re: Stretchy and Fetchy-1657 robot reveal
 

How did you get the hook for the recycle bin on to the bin at the start of autonomous?


Very nice robot!!

Re: Stretchy and Fetchy-1657 robot reveal
 

The auto zone is between the Scoring Platforms, so unless their robot goes past the Scoring Platform it is legal.

Re: Stretchy and Fetchy-1657 robot reveal
 

No worries, entirely legal

Re: Stretchy and Fetchy-1657 robot reveal
 

The field drawings has the divider on the alliance station side of the scoring platform. So it would look that if they were straddling the scoring platform, theyd be in the auto zone as well.

Re: Stretchy and Fetchy-1657 robot reveal
 

We can do that before the game starts

Re: Stretchy and Fetchy-1657 robot reveal
 

Figure 2-8 clearly shows the Auto Zone is in between the Scoring Platforms.

Re: Stretchy and Fetchy-1657 robot reveal
 

Yup, the picture of a field I saw had the field tape on the wrong side. You are correct.

I hope we continue to see vastly unique designs like this throughout the coming weeks. Einstein might end up looking like a giant Rube Goldberg machine.

Re: Stretchy and Fetchy-1657 robot reveal
 

How are you preventing the hooks from resting on/applying downward force on the bin?

Re: Stretchy and Fetchy-1657 robot reveal
 

3/4 "game changers" posted already. Very excited to see this executed so well.

Re: Stretchy and Fetchy-1657 robot reveal
 

Whats the last one? Im guessing you mean 148, 1657, and 1678.

Re: Stretchy and Fetchy-1657 robot reveal
 

Finally, a sweet conveyor.

Re: Stretchy and Fetchy-1657 robot reveal
 

Thanks - that was my follow up question also -

Re: Stretchy and Fetchy-1657 robot reveal
 

Wow.... another really good one

Re: Stretchy and Fetchy-1657 robot reveal
 

#TeamTether
Looks great! Kudos on an outside the box design. I'm sure the design process was a fun one. :)

Re: Stretchy and Fetchy-1657 robot reveal
 

Great name
filming in a dance studio was kind of awesome in a disco way

Re: Stretchy and Fetchy-1657 robot reveal
 

Yes. Yes. Conveyor belt. Hurray. :cool:

Re: Stretchy and Fetchy-1657 robot reveal
 

Impressive! Hats off to you guys!

Re: Stretchy and Fetchy-1657 robot reveal
 

The name so fits the function of the robot. Loving every part of it. Even the hook and drag for autonomous.

Re: Stretchy and Fetchy-1657 robot reveal
 

What a good looking robot, I cant wait to see what strategy goes on with your alliance partners.

Re: Stretchy and Fetchy-1657 robot reveal
 

I'm really interested in seeing the transport configuration for this.

Re: Stretchy and Fetchy-1657 robot reveal
 

This robot is simply awe inspiring in its simplicity and efficiency. This also can't be very difficult to drive.

Re: Stretchy and Fetchy-1657 robot reveal
 

World Champs?

Re: Stretchy and Fetchy-1657 robot reveal
 

This is I guess how the game (or at least task) can be fun - Great engineering solutions.
I see this and... did we miss the boat?

Out of left field - awesome.

What else is out there?

Re: Stretchy and Fetchy-1657 robot reveal
 

Now this....this I like.

Re: Stretchy and Fetchy-1657 robot reveal
 

gg israel

Re: Stretchy and Fetchy-1657 robot reveal
 

Thats such a cool idea I was hoping for something like this so Im glad someone did it.

Re: Stretchy and Fetchy-1657 robot reveal
 

we ff, surrender at 20

Re: Stretchy and Fetchy-1657 robot reveal
 

thank you everyone for all these comments!
espacially for the ones putting us on the same league as the RoboRanglers or giving us the championship before the first competition even started.
we never thaught our robot will get so much hype, and i hope it will satisfy all of you.
we'll meet the israeli teams at the Israel regional. if we win there you all could see our robot in st. louis

Re: Stretchy and Fetchy-1657 robot reveal
 

This is very cool. Great work. Hope to see it up close in St. Louis!

Re: Stretchy and Fetchy-1657 robot reveal
 

Man, the Creativity Award judges are really going to have their work cut out for them this year.

Re: Stretchy and Fetchy-1657 robot reveal
 

Great Robot!
Looking forward to see you at Israel Regional :)

Re: Stretchy and Fetchy-1657 robot reveal
 

I really love this robot. I've always wanted to see a conveyor belt strategy pulled off since I started watching FIRST events (2010).

I would love to see this against 148, only these teams, just 1v1.

Re: Stretchy and Fetchy-1657 robot reveal
 

Noooo! There are going to be 4 more very lucky bots on that field every time they go out I hope.

Now, we are only missing an auto crane bot!

Re: Stretchy and Fetchy-1657 robot reveal
 

Fantastic work. This is an amazing strategy- and very well executed.
Two questions- can the robot push more than two stacks at once or was that just not shown because of lack of totes?
And second- just wondering how that gets folded into transport configuration.
Awesome design overall, and good luck this season!

Re: Stretchy and Fetchy-1657 robot reveal
 

I would also like to know how any subsequent stacks are put on the platform. It seems like a capped six stack would be knocked over very easily if you tried to push a second stack into it.

Re: Stretchy and Fetchy-1657 robot reveal
 

Since the whole (second) stack would be be ejected by force on the bottom tote, I would think that said tote would be the primary medium for force to be applied to the first stack. Not the only application point of force, but the upper totes will tend to just bump against each other. If you carefully push a capped 6 stack from just the bottom, it should move safely, considering the low coefficient of friction of the scoring platform

Re: Stretchy and Fetchy-1657 robot reveal
 

Great name, great concept, great execution. I'm curious to see how the transport configuration works - that's got to be fun.

Good luck this season!

Re: Stretchy and Fetchy-1657 robot reveal
 

This is terrific. We brainstormed this idea, but decided to play the game a different way. I love your implementation. Out of curiosity, how many stacks can you build at maximum throughput?

Re: Stretchy and Fetchy-1657 robot reveal
 

3 stacks of 6 totes, all of them with containers. We won't go for pool noodles because of the time

Re: Stretchy and Fetchy-1657 robot reveal
 

Wow...

it's just...

wow...
