Shhh!!! We're trying to talk @Susquatch into it...

Ya what the heck! Have a little bit of discretion!

Well I've only experienced ABB and Fanuc, probably doesn't apply to motoman robots

That’s the spirit.

As a man who’s never worked on a motoman robot in my life, I can confidently say that I’de like to think they are the most reliable machinery ever made by anyone.

Found these, smaller size easier on the pocket book.

Grab a beer turn on your big screen tv and put this video on :

Robots run amok. Its very cool

I have to babysit some vintage ABB robots at work, and you are screwed either way. if they are new the parts are very expensive and if they are old the parts are still very expensive and now also rare.

oh the servo on axis 5 is acting up? well you have to take THE ENTIRE KNUCKLE OFF with the help of a bridge crane.

I don't know if I would take one even if it was free TBH



/end rant.

@Aarknoid what are they like in actual use? What do you weld with them? are they programmed with a hand held? I would imagine they are not productive with one off's or just a few parts but what do you think? Tell us more - it is great you are on the forum with some actual experience with these machines.

This is what I'm building. Appears to be fairly precise.

I picture the above with a string trimmer attachment......

well , the different types we use on my lines are a Debander, a sample pickup and place , and marking and labeling robot , on the other production line there is also a Nachi eye welder to weld the inside of a coil of steel to stop it telescoping out when it gets flipped on its side. The debander has a tool head that is just a one sided shear that uses a laser with a real good resolution (sub MM) to locate a steel band, cut it by swiping the blade under it and simultaneously grabs the now cut strip and feeds it into a strap winder to dump into a scrap bin. The sample robot takes samples that are cut off the main roll of steel off the cut table, puts it under a label printer and waits for the label to be tamped on , then picks the now labelled sample and drops it into a hopper for the lab to come pick up . the last robot is the one that causes me the most greif, it has a multi purpose tool head that has a giant inkjet printer head on one side to put the serial number on coils, and on the back side has a vacuum pad to pick up printed labels and place them on the coils right on the steel bands so they stick, opposed to the now oiled steel coils before they go to central shipping. this robot itself isn't a big deal but the solvent for the ink is MEK and all the old timers who used to worked here especially on that seem to all have kidney or liver cancers it seems.

they are all initially programmed i think in a variant of C and the teach pendant is used to move them manually into position to record that position into a variable the programs will use. all else fails if you need to move a robot and under power isn't an option its like moving a cannon on a pirate ship , lots of people bracing. in all honesty i would love to have one but would struggle to find a productive use to justify . , best I've seen is personal rollercoaster
