How high will the boxes go?
 

I am sitting back right now wondering what the average box height would be per game. What do you think your robot will beable to accomplish a game? none, 2, 3, 4, 5, 6, 7 stacks?????
Im guessing around 3 and 4.

We can stack up to 200 theoretically without tipping over... we can pretty easily stack the 8 or so bins we have... not to say that we're stacking or anything.

We can stack 1 high. Mad stack. :D

stack height
 

+How about that stack of 200 Can you please explain to me (not robot design) how you are going to be able to get 200 boxes on top of each other? I'm having problems comprehending that!!!:ahh: :ahh: :ahh:

Um, the whole concept of doing it involves telling you the design, which I will not do till a consensus in the team is reached to allow for the robot pictures to be posted.

I just need a type of robot unless ur robot is completely radical. I also think that if u can make a stack of 200 that would be completely and utterly POINTLESS!!!!!!

It's not useless...stacking 200 bins in a competition is useless...since you can't :) My design guess for that is having something insanely stable lift up the huge stack and have something else slide one perfectly underneath the stack.

You can do that easily. Just make stack of two and put in on a stack of 1. Take the new stack of three and put it on a stack of 1. Rinse and repeat. All you need is a pneumatic that can lift 1 stack high. Very simple and could be effective.

Yeah, after all, that's only 262.5 feet up- everyone knows that those bins can go up to 1,200 feet until they begin to depressurize

So maybe they have a REEEEALLY big stabelizer :P

stacking
 

Stacking the most will be not be the key i think. Thought a stack of five is good, i believe that it will be to easy to knock over this stack and will be the target of the opponents this year. Though stacks will be impressive to see this year and to see who goes the highest. It will be a race to see who stacks higher. Go team 303:cool:

Although we can easily stack almost infinitly high, (if the robot ever works) we aren't expecting more than 6-8 a match -- 10 at most

An infinate stack of bins has an infinate mass. Do you have a way to stop them from collapsing and sucking the entire universe into them?

Lol, doing a stack of 2 then adding, then adding, etc, is such a waste of time...

And I won't comment on the stabilizer thingamajig, though of course people would need some way of stabilizing it.

You'd probably get a Delphi Award for that :p lol

Our bot builds a stack of 3 within itself, and can support that (and drive around w/ it, etc)....But we can build higher than that, just beyond 3, the boxes at the top would no longer be supported.

Realistically, we'll have a minimum of 3 all the time....and if we need to, we can go "indefinately" higher.

stability
 

Has anybody tried stacking bins 10 high? The things aren't that stable, meaning a small jolt brings them all down.

Yes, most teams realize that which is why most teams who want to stack high are developing stabilizing devices.

we got to 12. theres a pic of that somewhere..in that other thread that was like this...

these bins are mad stable just look at this picture else im just mad crazy.

I'd hate to point out the obvious, but if you've got your whole weight on top of those bins, that's a lot of force keeping the bins up. It'd be fairly hard for someone to knock it over as in the pic, though without you, it'd be simple.

some one on our team has stacked 13 and held it for about a min dose that count?

Re: stack height
 

I belive he means that he will lift one box, place it on another, and then lift the bottom box. This will theoretically allow you to lift the boxes to an infinite height (not really, because they will tip, and eventually your stacker will not be able to support all the weight)

i can stack 5! our robot can stack...err...i duno how many...

*jeremy

I think the highest stack in the game will be ~8 high, and stacks of 2-4 will be more common, anything higher will be a rarity.

how high
 

my team is trying to stack it to 11. thick, if you have five its 55, your better off keeping it even

I must be missing something. How can you stabilize bins without touching them?

The bins only really need to be stabalized while the robot is moving them. When it sets them down they might, in theory, stay standing.;)

In theory, but reality is an tottally different topic all together. One of which our team shouldn't talk about because we have no robot to test our theory's of reality in reality with.:D

They might stay standing, but they would make a very nice (and easy) target!
So I'm not sure how long they'd stay standing. And even if you were protecting them, you'd have to do a very good job of keeping any opposing (or allied) robot from jarring you.

Best of luck!

I am dying to see a robot that can stabilize a stack of more than 3 and prevent it from A. being pushed over, and B. being pushed into their robot (therefore = to 0) against a robot designed to destroy stacks.

Our team is planning on stacking 4-5 high everytime a 6th is doable but really we don't perfer to do so.

Well you see, I earlier had designs, and a great strategy for making neat little pyramids out of bins......or just a random pile, either works, they can only go like 4 high, but they're hella stable...

Then again, there's the master plan of stacking 8, with a bot being able to carry/protect up to 4 bins...and can go under the bar.....but of course these are just designs....

This year they rejected my ideas and created a communisto roboto, a blocker, a very good one that lifts off the floor for extra grip....and that's why my designs haven't come into reality....

As promised, I'd get my designs posted as soon as I find a host robotics member to leech a scanner off of...

Our 'bot is dedicated entirely to stacking. We finished the stacking mechanism on Monday. Yesterday, we realized that we can't put one box on top of another, let alone having control over the orientation of the boxes.:ahh:

. . . Mmmmm, drawing boards . . .
