Canburglar Mechanisms
 
As we head into week 4, I'm intrested in Canburglar Mechanisms that were built at the competition? Our team is thinking about having a back up mechanism for this and we wanted to see some designs that were already out there.

Heh? Do you mean devices to pull RC's off the step, perhaps?

Yeah, they have been referred to on here as canburglars.

At GKC last weekend 1806 SWAT and 1730 Team Driven outfitted 1777 Viking Robotics with dual fishing poles/aluminum hooks during the first several matches of playoffs. Worked fantastically in autonomous (which only got a single trial btw). Can be done very easily with good results on a robot that is underweight and has pneumatics already.

Re: Canburglar Mechanisms
 
There are tons of videos from Weeks 1 & 2 up on The Blue Alliance. It'll take an hour or two, but going through the events and watching Quarter Finals yields some pretty nifty designs. There are some things we thought wouldn't work, but teams found a way to do it. There are some pretty awesome designs out there.

Do you have any pictures of this? Or an idea of how much it weighed?

There is some match video
https://youtu.be/fv-m27y7new
I would guess that the whole system weighed maybe 10lbs the poles weren't that much weight and the pneumatic cylinders were probably a pound a piece. The structure below was maybe 3-4 pounds.

Team 144 had them at Pittsburgh (week 2) and ran most of the matches refining the timing and accuracy. Cool to see that we had them in our initial design.:cool: We're built to play our part of the game! Check em out here. about 7:05 into the video....

Re: Canburglar Mechanisms
 
At the NYC Regional team 1796 the RoboTigers mounted a modified tape measure that was motorized to the midpoint of the uprights of their lift mechanism just before Eliminations began.

Something along the lines of a Stanley "Fat Max" style with a small hook on the end. They were able to pull up to the edge of the landfill and extend it like a snakes tongue into the top hole of the recycling can. It was a very simple yet effective way to accomplish the task and overcome the distance challenge of reaching the cans on the step.

The only time I saw it not work was when a piece of litter thrown by the opposing alliance just happened to hit it while extended. They reeled it in and sent it back out again right away with no lasting issues.

It reminded me of 2002 when we were all trying to have a piece of the robot extend back into our "home zone"

Mrcope9 17-03-2015 12:17

Re: Canburglar Mechanisms
 
We have a mechanism built, but due to weight restrictions and our robot not being able to start on the other side of the landfill, we probably won't be able to use it. But, we will bring it to both Bayou and Lone Star, and hopefully strap it on an alliance partner if possible.

Count on them improving this system. It is fast now, but likely will get faster and may even grab more in the future.

Re: Canburglar Mechanisms
 
We designed a can grabber last night in under 3.5 lbs. With a high flow valve, it could be under half a second to grab. With CAD, it's fairly easy to get right. I'll release the design once we fabricate it and know it works as-intended.

1.) 2D sketch the landfill & step, including totes/RB's
2.) Position robot in notional grabbing position in that sketch.
3.) Figure out where on your robot a can grabber would mount, then measure from that point to the center hole of the RC can
4.) Subtract that distance from 78" and that's the maximum height the pivot point can be at for the grabber.
5.) Add Pneumagics. Since the total rotation is ~90 degrees, the math for a bell crank is extremely simple.
6.) CAD mounts, fabricate them (CNC or any other plate-milling/cutting machine really helps, but isn't 100% necessary)
7.) Plan to get calibrations of angle on Thursday at the event

Re: Canburglar Mechanisms
 
Although our team doesn't have something (yet) that grabs the bins during autonomous, we were able to grab the bins from the step over the upside down totes once a member of our alliance (sometimes us, but many times our partners) cleared the landfill. It was a critical component of our success at Virginia this year, but we do hope to improve the system's capabilities.

tStano 22-03-2015 13:52

Re: Canburglar Mechanisms
 
3418: Robo-Riot had a really cool design in Wisconsin which went in the top of the can and expanded, allowing the can to be lifted. It wasn't the most successful, but it was the coolest design I've seen so far. It looks light.

I'll try to dig up some video. 2530: inconcievable had a more effective canburglar, which was definitely part of their original design, its just a 4 bar with hooks on the end. Very effective, although they didn't do it in auto.

Re: Canburglar Mechanisms
 
1538 did a really nice steal mid-match in the finals of Arizona east. Less than 20 seconds left, they saw the opposite alliance trying to grab a can, so they stopped pursuing the one they were already going for and grabbed that one out of the clutches of their opponent. Even though they lost, it was still a really good play.

It won't win any speed races, but we managed to mine a bit of green gold in seven straight playoff matches at Bayou this weekend:
  1. Clear the two end totes out - at the same time
  2. shove the rest of the upright totes to the left
  3. roll an inverted tote on its side
  4. roll that tote upright (and carry it a way)
  5. get the RC!

They are really starting to turn into the minibot, there are a lot of designs but only a couple are consistent and fast. I would say there is going to be a team at champs that is almost completely over looked because they have difficulty stacking but have a really fast can burglar. Somewhat like 973 is 2011 not having an auto but having one of the best minibot.

Re: Canburglar Mechanisms
 
Is there a list anywhere of teams with Canburglers?

Canburgler- A robot component designed to retrieve recycling container(s) from the step in autonomous.

My quick list would be:
27
33
118
610
987
1114
2056
2137
3322

My list is skewed heavily to Michigan and big name teams. I would also like to count only teams that have done it in a competition, videos are easy make when you have unlimited takes.

Add 1736. We consistently took at least 1 off the step during auto at Central Illinois. Video here of a 'race' to the step.

Here's a playlist if you would like to see how consistent we were. We took at least one off in autonomous in all but our first qualification match.

I think 3310 gets top slot in this list. 0.25s dual can grab before bag day.

You can't make a list of canburglars without mentioning 1678 who is now completely redesigning theirs again. The videos YPatrick linked to here show that both they and 971 had them at Sacramento.

16's reveal video showed a 2 container auto, and this video you can see them aiming for two and getting one.

At Alamo, 4063 had a 4 container auto that hooked onto the handles, and 2415 had a 2 container one (I believe 2415 only had it in elims though). I'm not sure if there are videos of Alamo recorded as they're not on TBA.

2848 got 3 out of 4 (and knocked the 4th over onto their side) here

This video shows 1986 getting 2

An updated list (adding every team that has been mentioned so far):
16
27
33
118
610
971
987
1114
1339
1678
1718
1736

Re: Canburglar Mechanisms
 
From the match videos that I have seen teams 118 and 1678 seem to be the fastest. Both robots do not need to move before releasing their can grabbers. In order to reach the 2 cans their arms extend out as/or after they are released.(required to stay below the 78" height limit) Most other robots must drive to the totes before releasing their arms.
Does anyone that has seen these robots in person know how the arms are extended?:confused:
Thanks
Also, 558 and 329 can be seen grabbing cans here

Team 141 (the WOBOTs) also have a canburglar mechanism. We went head to head in Match 34 at West Michigan. https://www.youtube.com/watch?v=ODyiCO4gpSU&list=PL6fCSvDccI_5gbCNQx9POAMI p7RVa0Xfc&index=30

We inadvertently had our getaway in "delay" mode, so we both had hold of the same can - 141 by the handle and 1918 by the lid. We took the can and also part of their "hand". Later, they stopped by our pit and "gave us the finger", decorated with a fingernail and knuckle. We all had a good laugh.

I'm going to disagree, it's 100% about who gets there first, it's very easy to prevent your opponents from grabbing it once your mechanism is there before you even pull them back.

Considering both us and 118 are scraping our mechanisms I think I can tell you all about them. I was a little surprised when I first saw their telescoping mechanism because was actually completely identical to ours which was kind of funny.

We both have round tubing held inside of square tubing. We used a bearing block on the outside of the square tubing, and an internal bearing block on the end of the round tubing inside to keep it constrained at two points while it slid.

We both extended our mechanisms by just running a string from our elevator frame down the end of the square tubing to the bottom of the round tubing. As the arm traveled through it's range of motion the string would pull the round tubing up through the square tubing the exact same amount every time it fired.

I can also tell you though that 3310's mechanism was faster than ours when we were running it with two motors (decided we didn't need all 6 for sac since it's getting scrapped anyways).

Hope that answers your question.

Um... I wasn't as surprised. Mostly because we copied 118's can grabber after watching their reveal video ;)

Steal from the best, invent the rest! And after working with them at Sac, and can accurately and emphatically state that 118 is the best.

no one ever mentions the PNW :'(

we have 1318 who's auto works quite well... and well that's actually all I've seen in competition (for auto anyways)

skunkworks robotics has retrofitted one as shown here https://www.facebook.com/Skunkworks1983?fref=nf

and we are planning on a similar retrofit (functionality unknown as of now, I couldnt go to the meeting today)

It was even closer than I expected though, practically down to the bearing brand.

That's because you are missing quite a few (unless you are only talking about teams that have built one at an event).
Here a couple from the Wisconsin regional:

1714-WI
2338-IL
2530-WI
2481-IL (Not at WI Regional but I know they have one)

There were a few more that I know I am forgetting.

624 has one too, but we've never actually used it in competition (no need to, we've been the 3 tote auto team for our alliance at both of our regionals so far), so I guess it may not count officially.

We do not have a canburglar but are in the design process. How do you build a world class 2 can canburglar with 4 lbs of weight to spare?

I don't know about world class, but ours works fast and hasn't missed one can in the five or six matches it was deployed yesterday. It weighed about 6 pounds. Its primary components are two fiberglass painting rods, a stick of .040" Vex VersaFrame, and two 1/2" bore 8" pistons. I bet my students who designed it would share it with you if you are interested, send me a PM.

537 has a canburglar mechanism (which we actually call a "hoarder"). :p
We only used it a few times at Wisconsin, but we're getting it all ready to go for the Queen City Regional next week. Our is basically just a 4 bar linkage with a hook on the end. The mechanism is the inspiration for our robot's name this year, Captain Hook.

Re: Canburglar Mechanisms
 
I'm currently designing a middle step can grabber like 610's but strictly mechanical actuation as an afterthought, until I realized that the empty step area is nearly 4 feet in width and then I have to add the width of the cans meaning I'd have to make an appendage with at least a 7.5 foot wingspan in order to grab both cans in the middle. I really hope my calculations are incorrect because that's a fairly large thing to be swinging around in the field.

Nope, you're right, you need a pretty large mechanism to do it. Also if you watched hawaii 610 brought out the same mechanism but with extensions to reach all 4 cans, that needs to be a little over 20 feet long to do it.

This an excellent view, you can see from here that 548 had grabbed the RC before 503 had even started to move.

How do both you and 503 actuate your canburglers? Does this difference in start time come mostly from the difference between the mechanisms, or does FMS initialization delay factor in?

We run a PID loop when auto starts to lower the grabbers. I don't think FMS plays that much of a delay factor. The delay should be less than 10ms. Are canburglers can hit the can in <450ms. I assume it would have to do much more with the mechanisms.

.045s? No way.

I went through frame by frame and it looks like .3s...seems a lot more realistic.

Congrats though. Your grabber looks like it's among the fastest that's been released.

Ours are two separate fourbar linkage sytems actuated by Banebot 775 motors attatched to Versa Planetary gearboxes using a 40:1 ratio. I'm sure Bryce can provide some insight on how 503 actuates their canburglars.

We had four CIMs pulling ours down with a 28:1 reduction. We use Command Based Java and CAN Talons (anybody on Northville willing to comment on their control system?). We think that we are applying power down for 1 second as soon as the match starts, but clearly there is some delay. Match one was constant 80% power and match 2 was 100%. We're still trying to figure out if this is our code's fault, something to do with the field, or caused by a chain skipping teeth.

One of our mentors took some 60 fps video of it and claims that our travel time was 1 frame shorter once we started moving :).

We use iterative based Java and run PID on CANTalons. In order to make ours faster we changed the P value

The obvious answer: apparently, not fast enough.

That was fun to be a part of, though.

Do those arms extend at all? Do you drive forward at all?

Re: Canburglar Mechanisms
 
During elims, we had a dual can grabber. Two hooks actuated by pistons.
The consistency and speed need work, but we ended up with grabbing at least one can in each of our playoff matches.

AndrewPospeshil 29-03-2015 20:41

Re: Canburglar Mechanisms
 
One interesting thing to note is that at the Livonia district (where the 503/548 "Battle of the Baseline Bins" occurred) the first three picks were all bin stealers - 548, 27, 503. Granted Robotstangs were seeded 2nd and had been 1st for most of the previous day, but neither 27 or 503 were in the top 8 during alliance selections - 10th and 12th iirc. This goes to show how control of the center bins becomes much more important during high levels of play. Even in a district playoff, alliances can exceed the 3 standard cans and will need extras. Especially in finals where games are win/loss, controlling these center game pieces is crucial. I'm excited to see how the FRC meta progresses. Last year's was really fun to see how the game gradually evolved into passing the ball as fast as possible without using the actual floor, but this year's bin stealing meta will be just as exciting I predict. I think the FRC community is gonna go wild when tug-of-wars become really common.

The arms do not extend at all, and are made of carbon fiber with custom water jet hooks clamped on the top. (I believe Alex hinted at this in the FIM Livonia thread). We use PID to get the arms to a position in which the hooks are just inside the hole of the RC. As soon as we are in position, we drive forward pulling the cans off the step and turn while retracting the arms back to their original upright position.

We fire them in queue before the match, however in the past we shifted at the beginning of autonomous. Its possible we forgot to take the wait out here but I don't think that's the case. At least our lord and savior (and programmer) Suhas says he took it out.

Re: Canburglar Mechanisms
 
Team mean machine has been developing some burglars in the gaps between events. Unfortunately, we had literally no weight to spare, (after factoring in other planned changes) so the whole thing had to be less than the weight lost by switching to mini cims (2.5 lbs).

Our current iteration has two modular mechanisms that can grab one RC each in about 0.5 sec. They attach with two bolts each, so they are easy to cheesecake. Each one weighs 1 lb and 2.3 oz!

I'll try to post a picture when I get a chance. Otherwise, they will hopefully be seen at pnw this weekend.

Re: Canburglar Mechanisms
 
We now have "fast" Dual-RC ability (we can be official "CanS burglar" in auto) woo hoo!!!.. thanks! GB via MK!

Cheese-caking in crunch time is a great experience for us as a second year team!

Already a regional was won with those very arms we borrowed.... via other bot (let you guess which fantastic team). Hope to do the same and repeat with hopefully a win in SD this week to make it back to STL...just missed in Ventura by 2 average points getting it to work to finals knocking eventual winners out. Was not ready in time for semi #1. Was for #2 and #3. Oh well we (with can burgling arms that work) live on...with that new found can burgling capability and bringing it to our second regional in SD this week should be fun.

We were most "modifiable" lost weight over 13 lbs and ..great for us we hope to put those arms to great use in SD...and hope to make it to STL with our bot!

Amazing add on in crunch time! just shows how one "bad over 100" trying to get it working (we got a foul with arms extended out of field) ... match knocks you out of finals by only 2 average points... I feel particularly bad for teams 696 and 1836...they both tried extra hard to get it working in time for first semi. Thanks for all your efforts teams ! Good luck rest of way!

We love the new can-burgling arms when needed. Thank you! You made us a better/stronger alliance partner.
