Best Can Burglars?

(I am hoping for some video links on TBA soon.)

These examples are show how overall speed, including quick return to full teleop capability, makes a difference in the score. All three of the robots in these examples have very consistent burglars.

548 and 27 did play against each other at MSC finals but they did not actually have can burglar battle, but team 1711 (on 548 and 1023 champion alliance) had equipped an arm after alliance selection very similar to 548's arms and was able to beat out Team Rush's arm in a battle. But video of the battle shows 548's arms in the background hitting and taking before 27's.

The reason Rush lost this battle was not because arm design but because Rush lifts their arms in auto so they can still get the robot set if their whole alliance does. I also did a video on my phone to see and while Rush's arms hit later than 548, their arms are still in the container before 548 can start driving. If it was a head to head match and Rush did not lift their arms in auto it would most likely be a stalemate until one decided to give up. To be the fastest can grabber you not only have to be the fastest arm in the can but also able to drive away before the other arm can come down. If someone else's arm can enter the can before you drive away it doesn't matter that your arm was down faster.

It would have been great to see 548 go up against 27 because they both lift there arms and are very quick.

Huge shout-out to 1711 for working with us and 1023 to get that arm modified and mounted in such a short time after alliance selection. Their mechanical, electrical, software and drivers all worked together to get it working so well so quickly.

We had contingency plans for if 27 chose to line up opposite us (548). Part of that plan involved what happened in F2, where the hook on 1711's canburglar was tweaked to have a much better grip on the can.

I'm sure if our alliance had tried that more than once Rush would have had a counter autonomous that didn't lift the hooks, and it would have been a stalemate.

I found a video of 27 and 548 during a qualification match at the MSC.

And a shout-out right back to you guys! It was a super risky move; probably the most risky thing that we have ever done in elims. But it paid off! If we hadn't won that war we would have been stuck with only 4 bins.

We all had a great time, and can't wait to see you guys at champs!

548/1711 beat 27 to the can in both Final matches.

Finals Match 1:


Finals Match 2:


Sorry about the Play watermark, these are just photos. If you want to watch the finals matches they are onDetroit Public Television. Finals matches are played on the bottom video at 05:54:36 and 06:08:06.

Wow, that is impressive, still amazes how 548's CanBurglars are able to get the can in such a quick time. Does anyone know if the CanBurglar on 1711 was an attachment from 548? The arm looks very similar...

Yes we gave them some cheesecake

Yes but getting the arm down doesn't matter if they don't drive away before the other team can get their arms in. It then comes down to who has the better arm. The strength of the arm can decide this as well as the shape of the hook.

I will post my picture I have later that shows that Rush's hooks were in the containers before Either team could drive away.

Something else to consider is the ability to disengage from the RC quickly afterward. I recall seeing some matches (I don't recall which team and where now) where the robot spent precious seconds dragging one or more RC's around, twisting and turning, trying to get them to disengage so they are available to be scored and so the robot can get on with stacking.

Lastly, many RC grabbers drag the RC's off the step and leave them on their sides. Unfortunately, many robots cannot score the RC's when they are on their side. Some can take RC's laying on their side and get them upright but that takes yet more time.

It was precisely the shape of the hook, in fact, that decided this can war. We lost a can fight the match prior because the hook design allowed them to slip out of the cans, so for the final match we took a pair of pliers to the hook and bent it around a bit more. It ended up working, but I can assure you that that fight was a tense moment for those of us down there on the floor.

All of the best (fastest) ones out of the PNW are single can takers: 4488's is fastest, with 1983, 2930 and my team (2046) also having very fast ones
