2022 FRC traversal climb prototype 01
Вставка
- Опубліковано 30 вер 2024
- Using LEGO scale model (1 stud = 1 inch), this mechanism is capable of moving from the L2 to L3 bar, and from L3 to L4. Uses one single stage telescoping grabber that is pneumatically actuated to determine angle. Based off of the more successful climb design concepts from 2013 (1986, 254, 3572, etc. etc...).
Definitely way simpler than I was thinking about!
damn this makes me really wish i was still in FRC
fuck don't remind me
lol this caused on 45 minute argument on my team on whether or not to go for the traversal now that we knew this strategy.
You’re my savior. We have a small team and we’re thinking we had to do something really complicated but a design like this would work wonders for us.
I am designing the climber for my team and it is a lot more complex but we want to get up there in less 10 seconds
amazing
fricken epic
This is interesting 🤔, nice job.
great design and prototyping approach! Could you describe (or post a picture) of the red arm? I am having trouble figuring out how it works. Also does this comply with the 5'6" max height restriction? At 0:15 it looks really tall! Either way I am really impressed with what you can do with lego! I am unfamiliar with lego motors/controllers, is this mindstorm?
Looks like it's using no motors, only pneumatics to control. Technic is real neat stuff for sure
Also as for the height limits, it does look pretty tall and doesn't look like it fits the 16" lateral limit either, at least from this test
The motors are power functions 1.0 then old pneumatic kits. Hard to get both of them.
@@spiderroom there's a single motor that runs the extension of the climbing arm. The rest is pneumatics though.
Impressively simple design: one motor and one piston
@@d73w80 ah didn't catch that, neat
Honestly i think this is better than the second one.
My what big hands you have.
Interesting design 🤔
bravo dAyi
When the red bar pivots outwards, I’m sure in relatively in full scale it goes past the 16 inch horizontal limit right?
I hadn't checked that dimension, but looking back at the video I think you are correct. I should have limited the movement, it doesn't need to rotate that far to be functional. The full scale drawings I have for this concept are all within the dimensional constraints, you'd never pass inspection if they weren't!
@@sforbs could you put a side view those drawings up somewhere? Personally I have been playing with this concept and don’t see how it works without going out More then 16 inches
@@vaughnkhouri1364 This was the initial concept sketch before attempting the lego design: cad.onshape.com/documents/a1bc2135603bf43bffb64b5b/w/ced6f951ec32b7eb70ce3c06/e/5744d3a996a2b672da4b2715
gonna have to center your mass to have that work properly, it scares me watching it. but nice job!
this is genius!
Are your black spring hooks a stock LEGO piece or did you have to fabricate those?

@@sforbs Thanks for the pic. I really love what you've done with this prototyping with LEGO's. We've done a bit before (2471), but never quite like this! Thanks for your GP sharing.
Can you offset the white arm to the "downhill" side or right in this video to angle the robot in the "hooked"position? This way you might be able to extend the grey arm and reach directly to the traverse bar?
Oh, and if you don't mind, what scale did you make this? I have a student at home quarantined, and he has tons of legos. I was hoping he could make something like this and then iterate it.
@@MrRiedemanJACC Mentioned in the description, the scale here is 1 lego stud = 1 inch. This has the nice effect that a 1x(X) brick with 1 plate on the bottom and one tile on the top exactly mimics the 1"x2" aluminum tubes that we build robots with. The CARGO game piece translates to a 3" ball at this scale, so a baseball is about right. Unfortunate that a regulation tennis ball is ~10% too small, it has just the right texture!
Did you powder coat the bars
pretty cool!
