Unique robot design?
I feel like many teams have almost the same robot design this year: meaning that the chassis is designed so that the robot can take 'in' the totes. Does any team have a unique robot design or strategy? I believe our robot is a little different from the common dedign(its not fully built yet so i cant show you how it looks like). Pictures would be great!
|
Re: Unique robot design?
You can't make a post like that, and not include pictures or drawings of your robot design!
:yikes: I think we will see a whole bunch of unique robot designs over the next ten days. |
Re: Unique robot design?
You'll find plenty of people eager to share their unique designs in about two weeks. Until then I doubt you'll get much.
|
Re: Unique robot design?
Right, we all will be presenting robots in about 10 days!
I asked that just because I didn't see what kind of team could get a remarkably high score. The field is separated this year and it's a totally different game from the others. The amount of score a robot can get is in a way limited(because of # of totes and those)… |
Re: Unique robot design?
I feel like the two different designs this year are going to be able to lift the totes up on the outside of your robot or lift them up in the inside of your robot

Pair a robot that can do this with another that can get a noodle and put it on top of the stack, and we could have a high scoring match... very high scoring if the other robot can stack well too. The highest score an alliance can get is 433. As Calculated in the document. |
Re: Unique robot design?
I think this year will be a year with more variation than typical. Yes, there will be a lot of elevators and those will certainly share a number of similarities, but after that, the sky's the limit.
There will be Double Stackers and there will be Stack On Stacks Stackers. There will be Landfill Munchers and Loading Station Loiterers. And that is before we've even started talking Cans. Upright Cans Only Machines will be quite different from Knocked Over Can Machines which will be different from Step Can Grabber Machines. Then there are noodles? There will be machines that are Noodle-Ignorers and machines that are Noodle-Centric. Also, lets not forget that some teams will design in mechanisms for knocking over stacks while making it look like an accident for when they need their alliance partners to fall in the rankings. Those are going to be crazy looking rigs ;-) (no, no, no... ...just kidding). Then there is the whole constrained Transport Configuration vs. virtually unlimited Competition Size. Not since bumpers rules effectively made "The Big Flop" illegal (I'm looking at YOU, Bill Beatty ;-) will we have robots with such imposing wheel bases driving on the Carpet Fields of FIRST. Then there is the whole crazy (but maybe crazy like a fox) idea of I'm-building-for-Einstein-and-I-don't-care-if-I-rank-dead-last-during-the-qualifiers Strategy (cough, cough, simultaneous 4 can auton grab, cough, cough)* Bottom line. I think this year will be a better than typical year for robot variety. I will close with this. I can't/won't share the Overclocked 2015 Robot just yet, but I will say that we've nick named her "Scorpion" and she's worthy of the name. Cheers, Dr. Joe J. *don't be a hater. I haven't let any cats out of any bags. With 1000's of FRC teams do you think your team was the ONLY team that thought long and hard about that idea? I myself stared long and hard into that abyss before shrinking back in horror (the horror, the long spindly, almost certainly rickety horror). P.S. This is a very tongue in cheek reply. Don't take this too seriously. Lighten up. Really. JJ |

I agree I feel as if everyone is either using a elevator with acrylic tabs or an elevator with a pheumatic squeezing arm. I think the robots who do great are the ones who are different for instance I saw one bot that is a conveyer belt. I'm still interested in what 254 has done to pick up noodles as that's the one game peice I truly ignored.
|
Re: Unique robot design?
While I do feel that there will be a large number of robots that are very similar this year, I expect we will also see some very out-of-the box designs that could get pretty complex. We still have yet to see much from the top-tier teams, and I'm willing to bet many of them will have some pretty unique designs.
|
Re: Unique robot design?
We haven't seen many recycling container bots posted yet.
There are at least a few of us building arms for that purpose. Video and blog There are going to be some amazingly unique robots this year. I can't wait to see what some of the historically creative teams come up with. (67, 118, 190, 469, and many others) |
Re: Unique robot design?
Personally I am waiting to see the CheesyOctopus: an 8 armed robot that can grab 4 cans from the step and make a stacked tote set and still have one arm for hitting walls.

Re: Unique robot design?
One possibility that people haven't mentioned here is the multi-bot (besides the Octo-254 previously mentioned). It is very possible to have 2 separate devices connect with a tether working together to either double stack or one stacks totes and the other tops off with containers. This sort of design is either going to take the world by storm or crash and burn. No in betweens for that design in my opinion.

Re: Unique robot design?
We are planning to make our robot a hybrid robot with a removable 'claw' to switch between our tote claw and container claw depending on our alliance partners.

Re: Unique robot design?
I don't want to post our design yet just because I don't want to post something that doesn't work, and we're still ironing out the bugs. But I think we have a fairly unique concept. I wouldn't be surprised to see a half dozen other teams do it, but it should stand out. Whether it stands out because it's an unnecessary gimmick, or because it's a novel solution to scoring in this year's game, remains to be seen. We have no frame cutout and it has nothing to do with the center bins.

Re: Unique robot design?
Reasons to keep secrets still exist, including the "it doesn't work yet" reason, the "we don't want anyone to iterate something that will score as much as we can" reason, and the "we want to surprise you, just for fun" reason. I always love the reveal videos, too.
From all the discussion I've seen so far, I think 1339 has one very common idea, one rare idea, and one that doesn't seem to exist anywhere else, yet. I look forward to finding out if other teams thought of it too, or passed it by. |

It'd be more interesting if teams posted stuff they were trying during the design phase; you'd get much better feedback and optimize the design faster. I've seen a few cases where designs we were working on were posted on CD and people jumped on them to find potential issues; that helped us build a better robot. I really can't see any negatives to posting design concepts at this point in the season. Think on this: If the Cheesy Poofs posted a complete render of their robot design right now, would you honestly scrap your current design after 5 weeks of work and start over with this new info? |

Re: Unique robot design?
I would certainly consider a re-iterated design based on a post from 254 or 1114, for example, if they were inclined to post their work even this late in the game.
I respect the teams posting here that want to open up the design process. Spectrum has been especially kind in their approach to the build season. And I'm not interested in being secretive for my team; we have little to gain from it, other than a bit of fun, and I doubt many teams would be looking at our design for guidance. But I also respect that some teams like to keep the element of surprise. It is one of our annual highlights as a team to watch and participate in the reveal videos. |

Hoping I have figured out how to share this. This is one of our special features. We plan on using this to clear out the landfill in autonomous or the early game. It's based on something many of you are familiar with this time of year: a hydrolic (in this case pneumatic) snowplow.

Re: Unique robot design?
You're right. We're a step or two away from full compliance at this point. Thanks for pointing it out and for the complement. The pneumatics allow us to have a straight blade on either side without compromising on size restrictions.

I also see some carbon fiber on your robot. We may incorporate carbon fiber, but at this point in the season, we may not. We didn't make use of carbon fiber last year either. If we're struggling on weight, some carbon fiber parts may need to be made. Our intake is like this! See Attached: Robot #3 is on its way! |
Re: Unique robot design?

That looks really sweet. I see that you guys either shortened or lengthened your wheelbase in your second iteration (I'm guessing the longer one is the newer one). You're right, they do look like mandibles. Ours is similar, though we've limited the range of motion more since they fold vertically.
We did do the belly in carbon fiber this year; one of our big goals was to teach the kids to do layup, and it's gone really well. We've also experimented with other parts, like gussets. Another big goal was to get the comp bot powder coated, and I'm pleased to say it will get back to us from our new sponsor Blue Flame on Wednesday. May as well post the rest of the pictures now too. The first is our stack of sliders; the second is the full bot as she stood yesterday. |

The new one's shorter, and the even newer final one will be an inch shorter than the short one in the picture. We can continue this conversation as a PM if you wish.

meet the requirements of a STACKED TOTE SET, at the end of AUTO." Also if you score 7 of your Litter pieces in RCs than you can score the other 3 pieces as unprocessed litter for 4pts each. You cannot score the opposing alliance's 4 pieces as unprocessed litter without incurring fouls. And speaking of incurring fouls the maximum score gets really interesting when you consider teams accidentally spilling their game pieces onto the other side of the field. There are no rules that say you cant score those pieces. Additionally if they descore your game pieces when they knock their game pieces over the step you gain the points they descored at the end of the match. Again, nothing says you cant rescore those pieces so that could increase your max score. |

- We think it's faster to pull them over than to move the totes first. - The land fill is a nice and organized area to pull totes from. Why would you want to mess that up when you can practice an efficient pattern at stacking and sorting them from their known starting position. |

So the concept behind the snow plow is based more or less on playing pool. When you start up a game you break apart the triangle of balls and then pick off easy shots. If you look at our robots design you will see that it can handle multiple totes at once, but the time it takes to get to these totes and be ready to pickup isn't instantaneous, we have a lift we need to adjust (we got rid of a lot of alignment time with el toro but its still there). When we crack open the field or goal is to space totes out so we have quick pickup lines and no idle time where the gap between two totes is large enough that our mechanisms are ready to pickup a tote by the time we get to our next tote. The other advantage of this as in pool is when you break it open you have the chance of moving totes closer to where you need them. With vision drivers should be able to quickly identify pickup lines by tote orientation and looking for basic patterns one of the key ones I imagine is a path of totes roughly in the same orientation that starts close to the scoring platform dives a bit into landfill then comes back out. What I do not want to happen is that drivers get stuck in the habit of going for the closest tote to them when picking lines and spending time on a stubborn tote. I can see that happening a lot to teams that are keeping the starting pattern they only pickup totes in a certain order when in reality that order might not be the best. Breaking apart the totes should make those decisions on which tote to go to next much more clear. Edit: Anybody got a better term then pickup lines in retrospect there has to be one... |

difficult wise, you have to look at how many totes are there, and the way they are packed in, and think about how many you have to actually move, it may not be the 3 or 4 you have in your shop, like a previous post said, it was going to be hard to move past the first row but I highly doubt the second. |

Early on, but too late for our team to turn back, some of the crew came up with something different. An overhead trolley crane. Collapsible trolley system, think an ez-up shelter, that covers the entire field. With a cable traversing system running inside it.
I would love to see if any team attempts such a design. |

Re: Unique robot design?
Yesterday we figured out a passive system for our robot to help it move a majority of the landfill zone totes completely out of the way in two moves, so we can get to one, if not both containers on the step. I predict with practice, that we can do this under 10 seconds, and with some slave driving, maybe under 5. We will be doing more testing today with the robot powered so we can really get an idea of how fast we can clear the landfill zone. The proof of concept tests we did yesterday were very promising.
Hint: It's somewhat related to a snow plow. Think ice instead of snow. Bonus hint: the entire "system" which is actually an attachment, can be cut from an 8x3 inch sheet of polycarb. |

Re: Unique robot design?
I would say that our robot is rather unique in two ways:
1.) It has 2 completely different lifts. One is a chain and hook system for stacking crates, one is a 4-bar for stacking containers and grabbing them off of the step. 2.) Our robot has two 45-degree angles in the front of the frame. This feature makes the crates self-align no matter what angle we are collecting from. |
Re: Unique robot design?
Quote:
It's based on our teams testing of a very realistic field setup, we found it rather time consuming and power draining to move the totes by way of snowplow, we really had to run into them to make a slight movement, and if they were off center from one another it makes it that much more difficult then we tried over the top and can grab two containers in 2 seconds and by 4 seconds be in the auto zone with two of the gray tots from the landfill dragged behind. Another issue is if you push the landfill to get the containr on the far left, you then have to to push the totes back were they were if you want to get the container on the far right If you want to do coop and you have the landfill totes pushed to one side it going to be difficult to get a stack of four if the other alliance can't get to that center |
Re: Unique robot design?
The most unique aspect of the robot that we currently have are two long arms, mounted to the chassis with bolts but capable of some back-and-forth movement due to surgical tubing. Once a tote is far enough into the robot, the arms naturally move in a bit to straighten the tote.
These arms can be made out of nearly anything, they're incredibly easy to install, and they are quite good at corralling totes. Because of their height, they don't interfere with the cooperation platform. They might also help remove a tote or two from the landfill zone. If teams currently have no intake mechanism and want to quickly make a good one, I would strongly recommend using ours. (Just send all of those letters of praise and adoration to Team 3807.) Here's a video. We're also considering some other unique things to do... for the most part, though, we just need to refine the mechanisms that we already have. |
Re: Unique robot design?

My original plan was to tether to all the recycling bins on the field before auto and reeling them in. Then the GDC made the landfill a volume and only one container set scoreable rulewise. The other deal breaker on it was when I asked "what next?" On asking that question I found myself with a robot trapped in the auto zone by a bunch of recycling containers and taking up a significant chunk of space that could be detrimental to team scoring ability. Securing resources is absolutely important in this years game. But you still need to score those resources for it to matter. |

and as promised here is some pictures of our container design pretty much done, auto still needs fine programming but tel-op works so i don't see why auto wouldn't .
description, we have two arms double jointed and when fully extended are approx. 5 feet. each arm spins separately in a 360 degree rotation. using encoders to signify where they are. the arms are attached to a lift. that allows us to place the container on top of a 4 stack, since they spin we can be stacking totes on one end of the robot then place the RC can on top just by spinning the arms around. once the RC are captured, we fold our arms up to center the weight , and the RC's are then directly over the frame. this design allows us to pick up a can from anywhere on the field and from any position, and we can stack two at the same time as well. all together 4 seconds to grab two rc can off the step and pull them into the auto zone. after our first trial we had to add a wheelie bar as when we first captured both RC the front end came up to high to the point were we could not drive now we drive a wheelie all the way into the auto zone then fold up. |
