Вставка
- Опубліковано 4 тра 2019
- Extending Reverse Stacker refined and remade. A new design that's more practical and compact while achieving all aspects of the game. Now including a double reverse four bar we bring you DR4B Extending Reverse Stacker (V2) for VRC Tower Takeover game!

Wow, That is sure some magic rope you've got there
Trio Gaming it’s the same material they use for hulk pants
Did you not notice the winches?
@@stevenyu4155 Nice
The rope has its capacity it can probably hold 5 cubes stable
That stack is 5.5 lbs and out the front of your bot, it's a tippy boi
Could weigh down the back of the robot with steel, mount the battery/cortex there, etc. to balance it out. Also, a software-defined anti-tip would help
indeed
yeah I agree especially with the arm moving at the same speed even with lots of weight on it
The roberbands would probably snap and it would be very difficult to manage it from tipping over it's way to ambitious
Pushing the boundaries of literal theoretical physics...
That is one strong dr4b to hold that many cubes
Pandaman Inventor We have v5 systems and rubber bands the dr4b isn’t a problem just the rope
I would personally be wary of a stack that high falling over. even with the twine/rope, I feel like that design might go bad really quick with a push
Michael Hesseltine Jr this also doesn’t show the physics of the tower I’m sure weight would impact that
Intentionally pushing and tipping the robot is a violation of the rule
I feel like
1. The stack is too heavy to lift/move.
2. The blocks would somehow squeeze out through the middle when moved.
You just gave me an idea for my team. Thank you. Good Luck. Hope to see you at Worlds.
im ready for everyone using this in the competition
Really great video and amazing idea. Now build and refine and you might just make it to worlds.
I feel like this would be a good idea if the slightest little push didn’t tip you over.
fantastic idea-- but those are gonna snap!
nice design
That’s really cool. I’m also working on a design similar to yours, but it doesn’t have the same capacity nor the same height. But I’m sure you’ll surpass the competition.
I LIKE WHAT YOU GOT
Danget. I was thinking of a very similar design.
I'd say its meta but it uses string
*Rubber bands
Lol I saw a team actually try this
It works for the first cube
Why not create some tension between the top double extender arms and the rope dispenser to move the center of mass back into/towards the center. (Rubber bands maybe.) therefore, the largest the stack gets, the more tension is created.
What animation software did you use to model this?
Zachary Serocki definitely cad
@@denizalpdogan3009 bruh
@@denizalpdogan3009 What did you think that they drew this and did it frame by frame?
He's asking how they animated it, not how they made the models. My guess would be Blender.
In any programming language you can do it.
You would need a massive weight in the base of the robot for that to work but great idea with the ropes!, I’d also think a simple claw wouldn’t be able to hold it and you would need something to support the cubes under
I think the tilt can be fixed with an internal reverse 4 bar, keep the entire structure, but remove the bar on the connecting the two opposite sides of the 4 bar. Then connect the claw on the inside of the robot, at the center, so its like the cubes are going inside. Its probably going to be really tight spacing, but it can work
Im in vex iq, not vex, but I still think this is a very creative idea! early in the season too! I think this level of dedication will get you to worlds!
Few issues- any type of band or tubing that you use for the stacker would most likely snap when picking up that amount of blocks, and if you have one large enough, it will sag when not being stretched.
- The weight would be very extreme and may cause the robot to tip. Will need a very strong chassis with lots of weight towards the back end, which could be an issue when not carrying stacks.
- the vrc game has lots of ruled allowing people to 'ram' into your robot, causing the robot to tip or lose all of the stack. Any simple bump can cause the band to snap
- all that weight can cause the motors for the lift to over-heat (I have had that problem with the edr 393 motors)
Precisioning would be a pain in the butt
Thought about doing something like this but with a cascade lift
Very interesting idea, but I'm a little skeptical of the cubes staying in place on the stack, also building a lift that lifts about 7 pounds of cubes wouldn't be easy
Que crazy
I would think you would use the stretchy tubing rather than rubber bands
It's string
It is a very good design idea.
How would you make it so that when the robot goes up ,with a stack loaded on it, the rope automatically rolls back up?
I’d be more than impressed if you can stop someone from tipping or wobbling your stack while you’re building it
Hey, great design. Quick question: what type of software did you use to design this simulation?
amazing idea! may i ask what software you used?
-1267E
Those cubes slip real easily, I think you need something more rigid than rope.
Are the orange string rubber bands
would string really support it?
You mean the Danny lift
I know that by now this is rather outdated, but did you share the CAD/animation files anywhere for this robot?
Hi, I am from Colombia I only have one year and six months in vex and I would like you to help me I do not know how to program the new VEXEDR kit could you help me please
I know I am asking a lot from you, but what software did you use to program this simulation, and by any chance could you give me a download to the vex arena? Thanks
rubber band snaps: people: :0 Opponents: :)
What software did you use here to make this animation?
blender
how does the clamping mechanism work?
Bryce Laffer looks like it’s similar to a clawbot claw thing that holds the cubes
1:07 excuse me wtf? there is no possible way that wouldn't fall over, it goes from like 10-0mph
⦖POLΛR BΞΛR⦕ the wheels don’t move either so...
What software do you use for the video?
That's ingenious but i can see a problem with weight
I see where it could dominate but then again go so very wrong😢
WHAT YOU THINK THE META IS GOING TO BE VERSUS WHAT IT ACTUALLY WILL BE
Have u ever eaten loctite the blue kind
Andrew Elmore that’s how u become gigantic brain
Yes officer this comment just over here
quick question...umm...I thought we could only use 4 inches of rope
e. An unlimited amount of 1/8” (or local metric equivalent), braided, nylon rope
Rope won't hold that
What is this animation magic! teach me the way!!!!!
It's Blender
I would really appreciate if you guys could put out a quick start guide as to how you guys did this animation I think it's really cool and even if you could just say what software you guys use that would be really helpful to many
Blender. There are a lot of tutorials just do a quick UA-cam search (how to use blender with vex)
@@rakibulchowdhury5400 thanks
If someone knocks it over though...
U could just bug it
I was dared to and was told it tasted like blueberries but I'm dumb enough then like a week later got bored and ate some it tasted like alcoholic blueberries
The cubes are a little bit bigger than the goals, so they won't sit in there without being diagonal. Genius idea either way!
Rebecca Horton no it fits
the cubes are not bigger than the goals, you can fit like three stacks of blocks in there if you do it correctly, two easily
FCKC0613 it’s impossible to fit more than two stacks but it two fits with a decent amount of give
Well, we know who's winning this year's game...🙄
how the fuck would that balance
There is no way that bot could hold that many cubes. This is just an animation. Can you please show the bot in action in real life? Thank you. I subscribed.
why on earth are you posting this?
Some ideas for competing in next year's game
I appreciate that 81K is sharing their design ideas.
@@tommy01nguyen We may as well let other people test the ideas we come up with
These are probably just fake leeks to get everybody to copy the wrong bot. They're probably hiding some crazy shit.
This is soooooo unrealistic I can’t
