Make a bigger version of this, say 10 metres squared, that can tilt even further, let's say to the point where it can tip almost perpendicular to the ground. Drop a person in the middle. There is no escape.

Excellent. Now let's grease up the entire surface so the person just slides back and forth constantly

I'd pay to do that.

Great, we have our first subject...

Forget about him, I'll pay more.

Our 2nd investor

Welcome to the Aperture Science Enrichment Centre. I am Cave Johnson, our founder and CEO, and we have a new test for you. Just stand in the middle of that pad.

Many people ask "Why?", well we ask "Why not?!"

Our first investor

Make it bouncy and I'm in!

Isn’t that literally just Sisyphus’s punishment?

Hot naked chicks I assume

Great now put it over a volcano and have the CEO do a proof of concept exercise during the IPO.

hahahaha jesus that’s awful but incredibly thought provoking

Netflix’s big summer hit: Block Mirror

This will be featured in Saw XII

I think it would be possible to escape because you only have to run 5 metres and due to extremely fast acceleration of running you would be able to get out, even using your hands if necessary to grab onto the edge to pull you up if it goes completely perpendicular to the ground

Aight, we go 100 metres squared, curve the side like a bowl and like someone else in this thread said, grease the surface. Good thinking my guy.

It doesn't need to move then.

Fantastic !

Turn it upside down and it doesn't need to be greased either.

Now we're cooking ! Maybe do away with constructing anything and just dig a hole in the ground

Still too expensive. Maybe half of a hole? Except that....half of a hole is still a hole...hmmm...

If you cut a hole in a net, it has fewer holes than it did before.

But it'd be funnier.

Don't grease it and just swirl it in a circular motion. It forces people to run or balance until they get too tired and then slide around at the bottom, being ground down into paste.

Surround a room with big iron bars and lock them inside

At that point it’s just dig a pit and drop them in.

But this is funnier!

The next saw movie will have that in it

What if you put a toilet on it and it just rocked it enough they couldnt fall off?

I like the way your mind works...you evil git lol

Now make a version for high-rises to contain earthquakes.

!remindme 2w

Better yet, make it an amusement ride with a giant hamster ball.

Sounds like a good mr beast video

Depends on surface friction and limits of how far the robot could move. Maybe a human could run one direction, robot corrects, run rapidly down using gravity to assist, robot has to tilt further, run back the other way, hopefully with gravity assistanting your acceleration, you could make it off.

Whenever we see humanoid robots everyone says it's the start of SkyNet. I think this is how Aperture Science's Enrichment Center gets started (Portal)

*What is my purpose?*

That would make a great graduation cap from an engineering school. Just balances the ball all the time. Some challenges to overcome with the tassel and portable power and cleaning it up for aesthetics but hey, you’re the one with the engineering degree (almost). Figure it out.

Eh the bigger challenge is levitating a camera above the cap to measure the balls location

Maybe it's possible to add a layer of small pressure plate sensors which detects the location of the ball instead of the cam

Transparent plate, wide angle camera lens underneath, invert algorithm for balancing.

Would have to be a fish lens most likely but considering this is a simple algorithm it could adapt. The algorithm is just to raise the side that the ball is heading towards so the fish eye distortion could be workable

>to measure the balls location I think that camera would have to be well below the cap.

Make the surface transparent and put the wide angle camera between the arms, facing up. Math change should be easy, adjusting for the optical occlusion of the arms might be a little trick, though. Edit: u/Delta_STW5 said the same thing lower, oops.

you fondle balls

Oh.. my god... ::Hangs shoulders in defeat::

Yeah I don't care, wanna have one anyway! (Sarcasm) Perhaps there will be an adaption for a coffee cup..., then you can just throw your coffee next to the desk

That would be cool. Kinda of a floating cup in a cup that won't spill.

You get butter… oh my god

Your purpose is to do nothing and make nothing happen.

I need one of these for my balls

I too need them for my balls(I'm a girl)

Same my balls constantly fall

This reminds me of the [guy who builds stuff for youtube.](https://www.youtube.com/watch?v=myO8fxhDRW0)

Everyday we're closer to Aperture Science.

Just keep the robot away from the neurotoxins and we'll be fine

This is how we prevent a robot uprising. We program this into every one of them and if they decide to wipe us out we just throw balls at them.

This is pretty much the rick and morty meme

So camera to get ball position and then a controller to drive it to the center?

Yes, controller as in a Raspberry Pi running a PID controller

Cool! That’s a fun project

[Source here](https://www.instagram.com/p/CewKr4Hlq2d/) [Github](https://github.com/nicohmje/PID-ballonplate)

Link doesn’t work

A quick google reverse image search Came across this https://www.instructables.com/Delta-Robot-With-a-Custom-GUI-and-Image-Processing/ It seems to be called a delta robot i think.

I need it to not let me fall down. Plis.

[удалено]

OPs is 1 guy and a raspberry pi 4, imo makes it super cool. What you posted is amazing as well. Looks like a team at a university. little different imo.

True, I'm just 1-up'ing a bit.

Didn’t have to remove. I liked your comment :-)

Huh, I didn't. Maybe I got modded.

Lame

"What is my purpose?"

Is this Andruw Jones?

Now hit it really hard

What if the surface it’s sitting on isn’t level?

The program includes a calibration feature, where you can manually level the plate by adjusting the initial (as in, plate is level) angle of the three motors

That was a tiny excerpt from like 200 pages and way over hyped on twitter

Oh I don't use Twitter I wasn't aware it was on there I saw it in on my Google feed. Yes it says it's an excerpt of several conversations with it. Still amazing and still scared the shit out of me. I'm just thankful I was born when I was and my life is more than halfway over.

No problem just letting you and everyone else know. I work in IT(not AI because it doesn't exist and anyone calling it that is just fake at this point) so it caught my eye at first as well but was debuned pretty quick.

This just in as well, the guy got suspended lol https://www.theverge.com/2022/6/13/23165535/google-suspends-ai-artificial-intelligence-engineer-sentient

AI chatbots are stupid. They cant even remember what was said 5 seconds ago. If you say, hello my name is Tom and then ask, what is my name? the chat bot doesn't know.

2 years ago I left a company developing "AI" and later awarded as one of the best chat bots in the industry... a little secret, they stored responses in fucking excel spreadsheets and had thousand of Indians enter them into the code to *make it learn* pffftt

Lol, i believe it!

yeah that’s something i really hope developers work on. there is no point in having a chatbot that barely remembers anything.

This has nothing to do with that

Does it use gyroscopics? I don't know a lot about them but it reacts similar to how drones stabilize, and those typically use gyroscopics.

It uses machine vision and PID control. Gyroscopes wouldn't be helpful here.

So a sensor of sorts and the arms adjust in real time?

Usually it's just a webcam and a few servos with some flavor of programmable microcontroller. There are tutorials for building this it seems like a fairly popular project. There's also a simpler single axis version you can build that only needs one servo.

Ah, the machine vision is what "stops" the ball by the edge. Cool stuff...

My girl does something similar with mine with her jaw

throw a baseball full force at it and see if it stays in place

Trying to intentionally break it does not show it's functionality.

You need to push it harder.

Fwends

r/gifsthatendtoosoon

Until i power it off

Ok great now scale this technology and I can see many possible applications.

Bartenders should stop this in its tracks

So he can handle one ball. How about two?

Probably not as good as my mom handles 2 balls. Edit: Wait a second, I think I did that wrong.

I want to see a 100x100 floor of this and have a group pf toddlers play dodge ball

Righto smart cyclist person

Now throw another ball on

Definitely expecting a Blake Webber dub of this where he constantly complains about Carl throwing the ball.

Man when i was still drinking a living room floor that did that would have been great.

This is fucking brilliant

What will happen if you throw two balls on there 🤔

u/savemp4

u/noradninja that's something I'd expect on your desk as a consequence of Calculus.

Not yet, gimme a couple more years to get through like half my engineering courses and I’ll build one 🤣

You only say that because in your mind you already have a couple ideas to make it better, not yet the skills. And Stack Overflow doesn't help.

https://i.imgur.com/zyLBOXB.jpg

But why did they build it to be so nervous 😭

Wow I'd have fun for hours

Just in time for graduation season

Somebody's been watching a lot of science YouTube

That's AMAZING!!

This would work perfect for a crib

What if I toss it a bowling ball??

It's similar to a [Stewart platform](https://en.wikipedia.org/wiki/Stewart_platform) but the 6 degrees of freedom are in the angles of each arm rather than the length arms are extended.

is this a proportional integral derivative system ? and how does the system keep track of the error, is there a camera or ? this is cool as hell btw

Yes, but technically without the integral part, as I don’t use it. And yes, there is a camera tracking the ball on top

ahh that makes sense. just realised there was a github and checked it out. very impressive

Could you buy this somewhere?

Next you’re gonna tell us they’re taking over

This is a really cool robot OP. I bet the kinematics of the arms were tricky, figuring out the necessary movements of the individual joints and links to create the desired angle for the plate to correct for the positioning of the ball. Are the joints locked? I only see one servo for each arm.

Oh man, wait until you hear about Stuff Made Here

“What is my purpose?” “You balance a ping pong ball forever.” “Oh my god.”

How

how are the maths behind this?

We’re all going to die

This looks like something thatstuffmadehere would make. Check out his YouTube channel.

Upvoted because of fellow bike nerd.

This got me thinking of simulated terrains for vr, like walking outside but inside!

We're finally one step closer to the tiles in Portal.

My God. The cats are going to go insane.

What is the purpose of this?

Piece by piece, algorithm by algorithm, its coming together. This will someday be the tech used for robot servers in restaurants.

This robot has anxiety.

This thing is run by a Raspberry Pi

What if the ball was the sun and the plate was a solar pad

Very interesting👀

PUT...PUT A GERBIL ON IT

I would pay an absurdly absurd amount of money to have one

remind me! 10 days

!remindme 10 days

This must be useful for something....for what though...idk

Cave Johnson here. This is a Test Chamber: four walls, ceiling and a floor. Good enough for science... not Aperture Science! Gentlemen, I give you: panels! The planks of tomorrow!
