DR4B Extending Reverse Stacker (v2) - Tower Takeover - VEX VRC 

Wow, That is sure some magic rope you've got there

That stack is 5.5 lbs and out the front of your bot, it's a tippy boi

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

I feel like 1. The stack is too heavy to lift/move. 2. The blocks would somehow squeeze out through the middle when moved.

Pushing the boundaries of literal theoretical physics...

That is one strong dr4b to hold that many cubes

I'd say its meta but it uses string

What animation software did you use to model this?

I feel like this would be a good idea if the slightest little push didn’t tip you over.

Lol I saw a team actually try this

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.

I would think you would use the stretchy tubing rather than rubber bands

1:07 excuse me wtf? there is no possible way that wouldn't fall over, it goes from like 10-0mph

Really great video and amazing idea. Now build and refine and you might just make it to worlds.

I see where it could dominate but then again go so very wrong😢

Danget. I was thinking of a very similar design.

Those cubes slip real easily, I think you need something more rigid than rope.

You just gave me an idea for my team. Thank you. Good Luck. Hope to see you at Worlds.

Rope won't hold that

What software did you use here to make this animation?

What is this animation magic! teach me the way!!!!!

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

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

I LIKE WHAT YOU GOT

Have u ever eaten loctite the blue kind

fantastic idea-- but those are gonna snap!

What software do you use for the video?

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)

This is soooooo unrealistic I can’t

how the fuck would that balance

how does the clamping mechanism work?

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

Hey, great design. Quick question: what type of software did you use to design this simulation?

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.

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 know that by now this is rather outdated, but did you share the CAD/animation files anywhere for this robot?

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’d be more than impressed if you can stop someone from tipping or wobbling your stack while you’re building it

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 ready for everyone using this in the competition

Well, we know who's winning this year's game...🙄

That's ingenious but i can see a problem with weight

WHAT YOU THINK THE META IS GOING TO BE VERSUS WHAT IT ACTUALLY WILL BE

amazing idea! may i ask what software you used? -1267E

If someone knocks it over though...

quick question...umm...I thought we could only use 4 inches of rope

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!

Thought about doing something like this but with a cascade lift

would string really support it?

rubber band snaps: people: :0 Opponents: :)

nice design

Are the orange string rubber bands

Precisioning would be a pain in the butt

Que crazy

U could just bug it

You mean the Danny lift

why on earth are you posting this?

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.

It is a very good design idea.

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

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

The cubes are a little bit bigger than the goals, so they won't sit in there without being diagonal. Genius idea either way!
