1785 are your bumpers high enough?





Why yes, yes they are.

Room for two and a half? (center one didnt quite make it :\)

Re: Scaling Club
 

That's quite the climb! May I ask how you get the hook up to the bar? What mechanism is that?

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

BERT 133 finally got our climber to work consistently at the Pine Tree District this weekend.

Re: Scaling Club
 

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.

Re: Scaling Club
 

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.

Re: Scaling Club
 

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

Re: Scaling Club
 

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.

Forgot to do this after Smoky Mountains. Here's team 2614 climbing in Qual 53 at the Smoky Mountains Regional.

1918 also joined this club at MSC. The drivers got better at it as the event progressed. The climb in Q182 is my personal favorite.https://www.youtube.com/watch?v=8fIa98Gj7bc
