What I meant was this obsession with likes and followers and bears, oh my!

A video is posted, then taken down, is hard to find, and praised, then questioned. Then....
I'll admit, it is a beautiful thing and I can't wait to see it in a match.

But this chumming of the waters for the hoi polloi just annoyed me.

Re: Team 254: World's Fastest Climb Teaser
 

How are you converting the rotary motion from the PTO to the linear motion of the arms? I heard something a while back about belts and pulleys in the lower tubing.

Re: Team 254: World's Fastest Climb Teaser
 

It's just two 233 arms with belts instead of chain.

Re: Team 254: World's Fastest Climb Teaser
 

For those of us less informed, what exactly is a "233 arm" specifically referncing?

Re: Team 254: World's Fastest Climb Teaser
 

Any of their numerous iterations of a telescoping arm such as this

Re: Team 254: World's Fastest Climb Teaser
 

do you have a picture of the drive gear box you'd be willing to post I'm sure me and many other people would love to see it

Re: Team 254: World's Fastest Climb Teaser
 

I've watched this video 3 times in the last 5 minutes and I'm still in disbelief that it's actually happening on the screen in front of me.

This is nuts.

What is this I don't even...

Re: Team 254: World's Fastest Climb Teaser
 

Done so much researching about elevator lifts. Forgot to look into Telescopic arms.... how does all that fit in there and how does it work?

Edit:

I understand how a "single stage" telescopic arm works, but what about a multi-stage.

Re: Team 254: World's Fastest Climb Teaser
 

I've never seen their arms in detail. Is the belt/chain fixed to the arms in someway, or is there a spool with a connection at the top like your 2011 elevator?

Re: Team 254: World's Fastest Climb Teaser
 

Are they mechanically connected, or are they independent of each other?

Re: Team 254: World's Fastest Climb Teaser
 

Yes. They are mechanically connected. There is a shaft that runs across the width of the robot from one drive gearbox to the other. This ensures that both arms go up at the same speed.

I am so amazed :ahh: . Seeing Shockwave in all it's glory like that just sitting there ready to fire off shirts is amazing. To bad some overkill robot climbing a pyrmaid is blocking the view. ;) This is inspiration at its best tell a great robotics team that someting is impossible and watch how fast it become mythbusted. :D

The only worry I have about this climb is that it looks like you guys touch 3 levels around the 5.8 sec mark. It's probably something that can be fixed pretty quick if it's a problem at all.

Re: Team 254: World's Fastest Climb Teaser
 

Since we are making sure this is autonomous, does it continue to climb after the buzzer?

Re: Team 254: World's Fastest Climb Teaser
 

No, because when the buzzer goes the robot is disabled and the motors cannot move any more. You can climb after the buzzer with pneumatic because if you get the solenoid switched the rams will move.

Re: Team 254: World's Fastest Climb Teaser
 

There are actually multiple ways to get things to move after the buzzer. Pneumatics is one(single solenoids or programming). The other way is with gas shocks. I've heard of teams using all types of releases for those. If you use a mechanical release you don't even need to release the gas shocks before the game ends.
