Fixing a KUKA KR-350/1 Robotic Arm: Part 1

[@johnmagruder6292]

Couldn't work with this guy for a minute! Best video of how not dismantle a precision robot.

[@saulcampos4404]

Any guidance as to why ? Never worked with one of these

[@tropcm]

i can only imagine how painful it would be to watch for a kuka technician

[@straatumleh]

It truely is, crinching from the get go. It is how not to do it. Every Kuka has an extensive service manual and special tools for service. But intertainment at the expense of a workhorse. LOL.

[@shanearnold1999]

I work at Volkswagen Volkswagen manufacturing plant and this is so painful to watch this dude seems to barley know what hes doing that's dangerous as fuck playing the guessing game wtf

[@5.0noah12]

@@straatumlehone of my favorite thing about Kuka. No one understands just how good their documentation is. I just recently installed packaging and palletizing cells, putting together spare parts list and training documents have been so much more fluent because of Kuka.

[@samuelvaldiviafranco7427]

Hahahaha im a oficial kuka technician and its true

[@hubertkaiser8581]

kuka technican go crazi, o kill the Elefant...

[@beachboardfan9544]

I've never seen one of these disassembled like this, we always drop the arm onto a portable work bench and then disassemble it at bench height.

[@key2010]

these people are professionals, don't doubt their ways, day noh da weh!

[@5.0noah12]

You can tell these guys haven’t done this before. At least tearing down a robot, respect for jumping at it and doing it. I hope you took this experience and continued to get better and have more and more fun working on Robots. Hats off. I would have personally drove the wrist down to a comfortable spot to work around it, get it supported by a crane/forklift hoist, e-stop the controller to kill power to the motor drives, and then remove the in line wrist assembly, set it down on a cart or platform and continued my way through each larger casting I could take off. Usually A4-A6 go together, then each other axis would need to be separated separately following the same type of method. Ofcourse making sure to route the cable set out as I disassemble. Best of luck!

[@5.0noah12]

A4-A6 go together as either one piece or two pieces, they make up the manipulator.

[@manr.9106]

It’s a Bavarian Robot, my friend! That’s the CLASS you’re talking about!

[@andrewallen9993]

if its a KRC1 its Bavarian if its a newer model its Chinese :)

[@waynemacleod3416]

the bolt at 13:49, that is corrosion. its is ionic corrosion caused by dis-similar metals. the white powder is aluminum oxide. that is the reason, that in modern building code, copper water pipe cannot be in contact with steel and aluminum.

[@yayinternets]

No, that's exactly what thread sealant looks like. Just take a look at Loctite white.

[@silversn4ke]

that is loktite.

[@pev_]

Why all the guesswork? I mean, couldn't you get the service manuals or at least structural diagrams and other such data from KUKA??

[@SianaGearz]

Because KZbin is made of clickbait and light entertaiment, and the audience wants to feel superior by watching people who appear not to know what they're doing, even if those just play it for a futile attempt at comedy?

[@peepopalaber]

Maybe ... to learn?

[@ray-charc3131]

It just a chaos.

[@icesystem7]

@@SianaGearzmmm no

[@JakeTheSnake509]

came here to say the same. detailed drawings exist

[@honeydane5646]

tomorrow is the last day of my internship at a Mercedes factory and I kinda fell in love with these robots 😍 beautiful engineering

[@ssnoc]

Probably the biggest advancement to humankind in the last 100 years - watching these robots build cars is mind blowing, the accuracy and repeatability is why cars today hardly ever breakdown anymore - in the 70’s it wasn’t uncommon to see cars on the sides of the road with all kinds of issues - today, you hardly ever see cars broken down - we’ve come a long way and these robots are a big part of the reason .... and of course electronics. 👍 - Excellent video and instructor.

[@ACERASPIRE1]

As good as they are they're the biggest advancment to human kind, nowhere near.

[@mission772]

Always entertaining to watch engineers do mechanical things.

[@alittlelad]

fuck no they are such amateurs its painful

[@NGinuity]

I find it humorous that I noticed IRC was on the wall above the Jeff cage and the first message I could read on the screen was "IRC is indeed on the wall above the Jeff cage".

[@josugambee3701]

You've just made my day :-D

[@guitarguy1337]

Awesome video, i wish i was closer to you guys, i'm an electrical engineer (enough to do my job) but primarily mechanical engineer, the fun you would have with my tools, it brings back my days starting out and struggling with things because i didn't have the right tools. I'll have to put a package of my old tools together for you guys, sending little bits from the UK wouldn't be worth while. I'm sure i have a spare set of Snap-on allen keys and 1/2" drive hex bits i can send across, metric, and my old imperial stuff that's no longer used in my industry. Keep up the good work guys, i learn alot on electrical things from you guys, and if i can return the favour and shed light on anything, give us a shout. I have some cool toys (robotics and automated heavy industry fabrication lines) at my work.

[@teddysponsler6220]

I already see an upgrades for this machine to take it to the next levels

[@wirehyperspace]

Think it would have been better to take apart in down position , weight closer to ground 💡

[@wirehyperspace]

It's watch out its covid of the brain, he keeps saying batman

[@Daniel_Palmqvist]

Most interesting and satisfying video i have seen this year. Love it, i could work with this 8 hours a day 7 days a week no problem for the rest of my life. i'm so jealous right now and inspired. Thank you, made my day.

[@enriquealonso6316]

these is a very enlightening video, Ive never seen something like that before, i got a call for a job, they asked me If I knew plc, peumatics and as well about robots, I never tried to get on that cause I tought it were kind out of these world, Now I can recognize lots of components and im more corious about the performing, conficuration, maintenance and installation of a kind of unit like these.

[@philclodfelter5994]

The only time I have seen that base was at KUKA in Sterling Heights Michigan.

[@LUISRODRIGUEZ-md4ic]

Beautiful robotic arm. I liked. Regards

[@CyberlightFG]

now I learned more than in 1 year working with it.Thank you so much.

[@thepetrarcticwar2778]

you dropped it YOU DROPPED IT!

[@i-make-robots]

Looking forward to the rest of this tear down. Thank you!

[@Solidworks_Tutorials]

So great robot. We love robotic

[@johnsamu]

The "8mm earth plate sign" may not have been a "sign of quality" but maybe it's an example of Murphy's law during production/assembly of this machine? Maybe somebody once forget to put the right clamp on the right place so the earth cable was not connected and some part got fried as a result. (I am just guessing). Because during production/assembly processes in general there's ALWAYS a chance for a mistake. So that's when you see that extra checklists/signs/procedures will be added to prevent the (mostly very costly) mistake that was made.

[@MrFernandoBedoya]

What an amazing video. Thanks to thegeekgroup to share this document. I have finished a training on Industrial Robotics here in Canada. A short vocational program where students learn some programming. We have 4 ABB robots a 1 KUKA in the lab, but most of the practices are done with ABB. Although we are just programmers it's quite important to know how's a robot inside, that's something we never saw in the school. Good job. I hope one day I'll have my own robot (KUKA, ABB, FANUC, Motoman or whatever it is) and bring it over my country to begin implementing robotic solutions. Thanks a million. Just one suggestion: Use safety gear when doing this kind of work.

[@webslinger2011]

Nice way to round those Allen bolts. Should have shocked them loose first with a hammer. Apply heat when necessary.

[@Buy-n-large]

is that a chat on the projector screen? is it public?

[@jd-uo8hc]

If you watch it on mute its actually kinda enjoyable.

[@philclodfelter5994]

Got to do a two week class on the KR-6 with Jeff Stancroff in Sterling Heights MI, they had several old robots with that color, also had the stainless one THE BUTCHER, also had a white KUKA that was for the radiology Dept for a hospital, it was a blast at KUKA

[@ChaoticGoodChris]

Jeff is awesome! I'm glad you got to study with him. Mr.Stancroft is the actual gentleman that our Project Jeff was named after. You may also have met Kevin there as well, he's the namesake of Project Kevin, our other giant Kuka. :)

[@funy0n583]

what do i need to do to work with things like this

[@MileSisters]

OMG. Thank you SO much for the look at the KUKA innards!

[@Armedlegally]

I cringe every time I see people use screw drivers for pry bars and punches. There is a proper tool for taking sophisticated machines apart...

[@skunkjobb]

Very nice and informative. I had never looked inside an industrial robot before.

[@Extra_Mental]

Switching the pc power supply was a huge giveaway...

[@marcuscesar1343]

It is cool to see something like this

[@TheXSairam]

how much power does this thing draw just moving this straws?

[@oscariglesias9004]

It hurts my brain to see such kind of work from such unaccustomed to work with tools people. It's a miracle they didn't brake anything

[@Drifthut]

what advice would you give someone who is going to be working with KUKA robots as a tech. anything they should research or learn about?

[@animesis]

You need to try working on the nuts and bolts of a rusted car!

[@tomtd]

Watching this it’s very apparent these people are not used to using hand tools. And take pictures as you go along

[@LReBe7]

I knew the drop was coming, but it still startled me!

[@davidgeorge1281]

Could they not have dropped the arm a little lower to work on it?

[@xartpant]

Smacking with a screwdriver on aluminum parts?

[@cheeto4493]

Well, It's an autopsy. I don't think they are planning on putting it back together.

[@SpenserRoger]

What aluminum parts? No gears are gonna be aluminum.

[@nickpierpoint4116]

How have these guys not heard kf using a longer bar rather than mashing it with air tools?

[@dawnchang389]

Great! And where is the next part?I can't found it.

[@ChaoticGoodChris]

Here you go! kzbin.info/www/bejne/onncfGWqf9V4i7M

[@antonviper7803]

Sad, if this Kuka wasn't free to you, and you bought it with your own funds, you wouldn't be so quick to kill it :O

[@ChaoticGoodChris]

Hello there. Jeff was a factory prototype and because of that we were required to ensure that it would never be released to the public domain. We were contractually obligated to dismantle it at the end of its useful life in order to protect certain manufacturer secrets. His parts will live on as future displays and small demos here at the lab.

[@antonviper7803]

Sweet, I gather it was pretty worn out then, ahh well.. still a shame. The contract more so, I think, prevents them from loosing a future sale! There may be some old secrets in there, but the general operation is now quite well documented. Well done on inspiring and sharing this engineering to all. Cheers.

[@rustyscrafts]

@@ChaoticGoodChris I'm really late to the game here, but that should be the pinned comment or in the description. Without explaining why you are disassembling, this comes off as more of a painful "amateur repair" video. Also, you might not have gotten as much flak from the comment section! :)

[@marmoladarolna]

Saturn 5 never exploded thanks to over engineering. Please go to details what makes KUKA so good. From shape of the gear teeth to the shape of cast parts of the arm. What makes them low noise and stiff. Hopefully new generation of mechanical engineers will pay attention to this KZbin channel. Universities are behind on practical education.

[@tejeshwvardhan1165]

Stepper motor?

[@nightmarecuiture]

Release the shmoo!

[@sgtrock68]

LOL, I've done things similar to that (3:00) to make damn sure there's no way we can go back...OR backwards. Only onward and upward! It seems like it was always the kind of system that would keep the whole plant on its face if it failed. It never did though.

[@tekneiq]

I jumped when Chris dropped the hard drive, lol

[@xl000]

you don't get more torque from an impact driver that your wrist can provide though.

[@DailyDrives]

Still seems like it would be a better teaching tool together than in 100 buckets of mangled parts. With the lack of care you guys took in taking it apart, it seems like you will have a hell of a time putting it all back.

[@DJjosher]

Painful looking at the tear down of this robot. 😬

[@MsSomeonenew]

Don't mind the jokes, but keep them until after you explained what you are really doing, hard to take anything seriously/follow along if you are repairing joke problems.

[@woodstoney]

OK so where's the manual showing parts for disassembly and why is the guy afraid to touch it with his gloved fingers? Might get a bit of grease on them? Really? Qualified ? Hardly.

[@AnmolModur]

Why are you not using LOTO tags? It should be industry standard.

[@RambozoClown]

Poor Jeff. He could have made a really nice ride.

[@unknowndomain]

Given they said the motor breaks weren't so strong it would have been a bit risky.

[@fenderrexfender]

8:09 the belt teeth run on a smooth self-centering pully? ya whoever replaced the belts botched the gasket...

[@filiprenberg1974]

Just take a pipe to extend the wrench, it'll give you a lot more power to unscrew those bolts

[@glitchinthematrix5761]

How many geeks before one of them think about leverage?

[@bgubl87]

They tried to unscrew 10.9 screws with a shitty impact drill. Have you evere wondered where all the load from the robot is screwed to?

If you look closely you can see that the secret key is hidden on the side of the rack!

[@metalhead2476]

This video is more like "how to kill yourself slowly and painfully if the brake system fails". I work with these damn robots and when I touch up positions I use a piece of metal that's 5mm thick(just because it's easier) I just need those 5mm of clearance. Anyways. Because it's in a "weird" position, the brake system CAN and WILL FAIL from time to time. Even when powered on. F*ck....

[@frankasauruswrex]
