Canburglar Mechanisms

[safiq10]

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.

Well, a piston and a polycarb hook is all you really need right?

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.

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

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. We're built to play our part of the game! Check em out here. about 7:05 into the video....

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"

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.

I haven't seen anything like ours yet.

How did you do that?

I was able to catch 1678's Canburgler in action at CVR.
Count on them improving this system. It is fast now, but likely will get faster and may even grab more in the future.

What team is grabbing the yellow bins?
