Scaling Club

[Arhowk]

we (1684) just got ours working at Lansing, our rookie team (5460) has been consistently climbing since Kettering (sorry too tired to find videos) https://m.facebook.com/photo.php?fbi...4899&source=49

1094 won the Creativity award in Central Illinois for our hanging device.

1410 scaled in every elimination match/when necessary in qualifications at Colorado and inconsistently during Arizona North.

4490 can scale, but we had some complications with our climber that prevented us from climbing this year. However, we were able to.

Were a first year rookie team and we attempted many times at gtr east but finaly hung in North Bay.https://www.facebook.com/CANbotics/p...003340/?type=3

Team 4004, the M.A.R.S. Rovers, achieved consistent tower scales last weekend at West Michigan. Our robot's 'Intellihook' activated the winch automatically as soon as the hook made contact with the bar. It took the guesswork out of our drivers who couldn't always tell if we were hooked properly or not.

Sorry for the fuzzy picture... video to come soon.

What are you using to shoot your grappler claw up to the pipe? Is it a spring, pneumatic cylinder or combo of the two?

It is a steel compression spring. The trigger is a pneumatic cylinder operating a simple over-center lever.

The dart itself has some bearings that ride the surface of the trigger cam to get a repeatable release.

1511 at FLR

Note the "Welcome Leo" sign - Larry and Leann Lewis (lead mentors) had their baby the day before this picture was taken.

Thanks to Mike at 233 for helping us early on in build season with some design problems!

Here's our rookie team #5830-The Irrational Engineers hanging at the Central Maryland event (finally did it around our last match, after a lot of tweaking)

Team 25 scaled in 14 matches at the MAR Bridgewater-Raritan District Event. Here's a good clip: https://youtu.be/rp-92muWDEc

Here's our team this past weekend at district championships. It took awhile to actually get our scaling arm to work, but it's official: 1099 is part of the scaling club now.

3620 used our scaling mechanism during our last match at MSC. It was installed late Friday. We played our last two Saturday qualifying matches and our first two octofinals matches without using it. Came up just short in OF2-3 -- it would not have helped at that point since our scaling partner had already lost a drivetrain gearbox, and was stuck in the other courtyard.

Now that it is in the bag, we look forward to practicing with it at CMP. Good to have it, even though we might not use it often.

Team 1250 just joined the club at MSC!

We removed our old scaling system which didn't work. (It was 2 pneumatic tubes with hooks at the ends of them both. The hooks would get rotated and misaligned resulting in a failed scale. The entire process was very slow.)

We prototyped our new system on a wood mock-up of our main robot arm and practice bot chassis, put 140 pounds on it and it lifted like a charm! (Yes it was slightly excessive but the bot does weigh less than 120 lbs)

How it works is the scaling arm sits within the main lifting arm of the robot with a strap connected to it and a winch at the base of the chassis. The main arm raises to a certain degree set after twisting the action button 'Scale Extend', then the scaling arm deploys by releasing a door lock at the end of the robot and swings upward.

The driver has a secondary function to 'bump' the main arm up a few degrees to help latch the yellow hooks onto the rung. Once hooked, the 'Scale Extend' twist button is pressed down and the winch lifts the entire robot up. After the desired height has been reached, the action button for the low bar degree set stops the winch and finishes the scale.

Personally, I stop the lifting motion after 1 brick is showing below the bot giving a clear indication that we have scaled and no damage will occur to the robot.

The entire process from start to finish takes around 8-10 seconds

MSC - Qualification Match 192

135 is a proud member of the scaling club! We have an extension off our shooting arm that folds out and up to the bar with a magnetically attached hook. Once the hook is on the bar, the winch pulls us up disconnecting the arm extension from the hook and climbing the tower.
