Thread 106985121

Best fucking trend happening right now.
They even come up with open source firmware to make those old machines work again.
Those shits easily cost 100k when new and most just get thrown away after one or two decades of service.

A friend of mine uses one of those to "hold" heavy parts in every position he needs them to be for welding. Basically like a giant version of those soldering grippers that hold your PCB in place.

sir this is the consumer board

Where 2 cop?
I see them on eBay but they still push into the 10,000s.

>>106985875
Really depends on where you live.
In some places it's as easy as just asking around at multiple companies until you eventually find one that is replacing some old with new ones. Sometimes you can even get them for free.
The real issue though is that those are quite complex machines and you won't have any documentation.
But that's where open source groups are currently working on. Basically universal firmware kits for popular industry robots so you can get them to work.

>>106985121 (OP)
Make sure it has collision detection though.
We had a robot arm at university and it was a pain to use because it had no collision detection so if you hot anything it would keep pushing until you hit the emergency stop.

I made it play chess once for example, but forgot to add the thickness of the board.

>>106985946
OH YEAH.
Those things absolutely can turn into your worst nightmare if you don't know what you're doing and have multiple safety lines in effect.

>>106985121 (OP)
theoretically speaking, can you build a handjob machine with these?

>>106985977
You wouldn't need a man sized industry robot arm for that that can lift entire cars but yeah there are smaller ones and you can absolutely do that if you know how to program and how to make a soft and gentle gripper that won't shred your dick into salami

>>106985993
>You wouldn't need a man sized industry robot arm for that that can lift entire cars
but that would be part of the thrill, methinks

>>106986012

>>106985931
Might try it. I know a few businesses.
>The real issue though is that those are quite complex machines and you won't have any documentation.
All too familiar with it. Would it kill the manufacturers to write up a decent readme?

Link?

>>106985977
Yeah. I've seen one made into a dildo machine. Principle is exactly the same.

Fucking hell.
Imagine having one of those fuckers inside your garage, something goes wrong with your script and it goes absolutely crazy with you still in the garage.

NOPE.

I messed with an old robot arm for a while, it was tabletop sized used for pick and place at labs or something like that. No open source firmware at that time but it was pretty fun figuring out the shitty BASIC dialect it used.

>>106986105
always have visual contact with the thing while also having your hand glued to the emergency stop button
there's stuff like the Bolt robot arm used for film and photography which is just a repackaged industrial arm, they mount cameras on it mostly, I've seen some pretty lackadaisickal handling of that thing, it's a miracle more people don't get hurt

>>106986069
I think if you can get one of those small bench top ones, that's great.
If all you're seeing is those huge ones like the FANUC, I would avoid them, even for free.
They take up a shitload of space, and don't have as high a payload as you might think, but still move a lot of non-payload weight in the arm body so can still do a ton of damage. Big enough that it would be really hard to properly dispose of as well (which is why their being sold cheap).

Did you see the clip where he's well within the working envelope while he's still testing if it even works?
I've heard about these knocking down walls, and they could kill a person pretty easy.

Also, it's all fun and games until the robot thinks you are a box of vegetables.

>>106986069
If I bought one of these, would working with it help me get a job in robotics? Or is it too outdated to be listed as experience with industrial robot programming?

>>106986242
>If I bought one of these, would working with it help me get a job in robotics?
Yes. 100% it would.
>Or is it too outdated to be listed as experience with industrial robot programming?
It might not be completely transferably to whatever you work with, but that's not the point.
Being the kind of person who sets up one of these in your spare time is what you're showing them with a project like this on your CV.

>According to the indictment, Samuels wrote the particular piece of computer program responsible for the robot malfunction.

Society must protect itself against programmers who make careless mistakes or else no one will be safe, least of all our families and our children."
>"By Jove! It looks like he misinterpreted the y-dots in the formulas as y-bars, and he made the same mistake for the x's and the z's. He was supposed to use the derivatives, but he took the averages instead. He's guilty as hell, if you ask me."
Is that first one even real? It reads like satire.

The basics of the story is very similar to a real case though, but it was some hobbyist that had programed it himself.

>>106985146
>"hold" heavy parts in every position he needs them to be for welding
so he uses them almost exactly as they are being used in actual factories?

>>106986682
Yes but in factories everything is automated while he just uses it as his 3rd arm, manually controlled. Robot+human interaction.

>>106986069
Just finished the video. Very cool, anon. Thanks for sharing it.
I was watching this thinking "but didn't he just {...}?" a few times. Probably a good sign that it's engaging enough for that. I'll share it with my research group some time.

>>106985121 (OP)
Huh I could pick a robot aka manipulator arm for free at work but it's 500kg and what they never show you is huge 200kg rack with controller that goes with it.

Can you fuck it?

>>106986265
The Case of the Killer Robot is a fictional scenario for ethics teaching and discussion purposes.

>>106985121 (OP)
Use case for robot arms for hobbyists? No but seriously, of all the heavy machinery you can dabble with they are the most useless. Yes, even as a learning exercise.

The guy behind that video is a one man army, very few people can do what he did.

Small desktop welding robots have appeared on trade shows lately but that for low volume serial production.

I did basically the same 10 years ago. More people can do those things than you would think. But they are professionals in the industrie and don't make YouTube videos.

>>106987974
oh wow

Women want to tame pitbulls and men want to tame industrial robots

>>106988410
>I did basically the same 10 years ago.
Yeah and your dad works at Universal Studios

>>106986105
is there a desktop sized one of those?

>>106989437
only fully selfmade using 3D printing and lots of tiny servos

>>106989453
ye but those are wobbly af
>servos
bleh. stepper motors with encoders

>>106989437
Yes, they are often called cobots

>>106985121 (OP)
I almost got killed by one of these fuckers. The big robots will easily go through a wall if you make a little oopsie woopsie.

>>106987974
>Use case for robot arms for hobbyists?
Suspending your robowaifu out on a boom (just replace the camera here), so she can get around without having to be able to walk just yet.

>>106989431
Look, designing something like this is not as difficult as it might seems.
But the people with the skill to do so are usally not unemployed like you, so it makes sence that you have never met them.

>>106989437
Yes, but usally they are still >100kg and very expensive.

>>106990661
I always feels such tension watching videos where people strap chair to one of those and then make crazy ride out of it. One mistake in programming and it'll spread you over concrete like butter.

>>106985124
They also probably have intense wear and tear and require replacement parts for literally everything.

>>106987974
i-it's fast!

>>106991798
OTOH it's built for assembling auto parts nearly 24/7, while in your hobby usecase you're probably never gonna get more than a couple days cumulative out of it, if that
