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

[Galum]

You guys make me proud :)

[TDav540]

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!

[pntbll1313]

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!

[JamesYao]

Awesome

[Lil' Lavery]

Beautiful solution.

[Loose Screw]

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

[Nuttyman54]

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

[Mike Marandola]

Wow! Really nice job.

[Kevin Leonard]

Wow. That's incredible. Phenomenal work.

[The_ShamWOW88]

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

[Bryce2471]

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.

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 :)

Thanks for doing my job

[barn34]

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

[dodar]

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

[samfruth]

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.

Thats what I was thinking.

[AdamHeard]

Looks familiar;

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

[Boltman]

Amazing awesome.

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


Very nice robot!!

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

No worries, entirely legal

[dodar]

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

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.

We can do that before the game starts

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

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.

[Electronica1]

We can do that before the game starts

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

[IKE]

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

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

[Fields]

Finally, a sweet conveyor.

Thanks - that was my follow up question also -

[JohnFogarty]

Wow.... another really good one

[JVN]

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

[colin340]

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

[g_sawchuk]

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

[jruppel]

Impressive! Hats off to you guys!

[D_Price]

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

[hunterteam3476]

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

[Sohaib]

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

[Mitchell1714]

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

[brrian27]

World Champs?

[page2067]

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?

[Andrew Lawrence]

Now this....this I like.

[PayneTrain]

gg israel

[Sperkowsky]

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

[Abhishek R]

gg israel

we ff, surrender at 20

[ronlottem]

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

[Nick Lawrence]

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

-Nick

[Dan Petrovic]

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

[sagi34]

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

[Anthony Galea]

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.

[cglrcng]

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!

[Paperclips]

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!

[Isaac Ash]

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.

[BBray_T1296]

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.

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

[Jacob Bendicksen]

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!

[ToddF]

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?

[ronlottem]

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

[mrRoboto]

Wow...

it's just...

wow...
