My robot idea for this year implements the ability to do a low tier hang just to bring the robot off the gound and get an easy extra 3 points. Any advice on mechanisms that work well to do it quickly? My plan is to make a decently fast robot to put a goal in the positive corner and then run and hang all in the last 5-10 seconds.

Quick pneumatic hang similar to b tier quick hangs like this years would be good. You could also use a passive hang if you prefer that. There are so many designs, so it is up to you!

- Over Under style b-tier hang (uses pneumatic actuators to pull the robot up, which is a lot quicker than motors)
- Over Under style passive a-tier hang (see Hailstorm’s bot, you just drive up, get stuck, and drive reverse until you’re balancing on the bar). Pneumatic actuators just pull it up, nothing else. Would recommend this over idea #1

I had an idea for a pretty quick hang similar to what we did in over under at the start of the year. If you just have two hooks that pivot up with pistons over the center of mass of the robot, then you can just drive into the bar and grab on and hang passively just above the ground for an extra 3 points. It’s pretty good for the future too, cause you have to be off the ground to grab on to the second bar, so if you wanted to make a higher climb, you could start with just a passive hang and go from there.

Something that many people have been considering are passive/“slam” hangs that do not require motors or pneumatics.

I thought you needed pnumatics to raise the mech to allow you to hang?

I’m confused on how a passive/“slam” hang works. Can someone please elaborate on how it works?

Look up “vex over under passive hang”

This fully counts as the lowest tier of hang, so I’d suggest adapting it to fit the triangle shape of the new hang bars and making it release up through pneumatics. What’s great about this is that it’s a 1 time mech with no need to come down. Just a single actuation and ramming into the bar😊

Use 2 pneumatic pistons to deploys some poly carb that has a slant and notch, this makes you hang time 0 seconds and as long as there is enough pressure to lift some poly carb on some linear slides in the system it will work. I would recommend having a hard stop end point so you don’t hang your robot on pneumatics only. Just look up slam climb
