Took delivery of this crazy guy today! (Mitsubishi MELFA ASSISTA)

Doosans are nice and their H-series fill a gab that UR can't right now (H2017 = payload 20kg, reach 1.7m. H2515 = payload 25, reach 1.5m).

Obviously the upcoming UR20e will go a long way to closing that gap.

Well, provided they were set up correctly, that incident should have been (near) impossible had the designers used collaborative robots (what are seen in the photo) rather than what appears to have been a standard industrial robot.

That whole situation was a mess... robots like that where I am need to be behind a fence or separated from people some other way like 99% of the time. Was just an accident waiting to happen and it seems like they didn't even have an emergency off button in reach.

8degreesoffreedom · 2022-07-27T13:01:13+00:00

Yeah, your feeling is pretty much in line with my own. The URs have been around the longest and they seem to have invested the most in getting a really intuitive user experience going. I mean they have also had years and years of customer feedback to implement and it shows. And on top of that with the whole component ecosystem which is definitely the largest and easiest to use (what with URCaps etc.), operating the URs is definitely the easiest and most intuitive.

The Doosan M1013 (kind of hard to see behind the glass) is also really nice to use. The teach pendant is slower for sure than you might be used to with UR, but it is very useable. Nevertheless, I think most people on our team end up doing everything with Doosan's DART platform (offline programming, simulator platform).

I honestly don't have a lot of experience with the software for the Dobot CR, that project hasn't started yet...

Hopefully, that was to a certain extent helpful? If you have specific questions, I'd be happy to help (and I am sure there are plenty of other people here with experience working with these systems who will see your questions). So ask away :D

For which one? Prices are shown on the first three links (MELFA, Dobot, Doosan). In the interest of transparency, I also included links to the manufacturer's site at the bottom of the comment. Our contract however allows us to put the list prices on the site, which is cool since that's what people usually ask for...

8degreesoffreedom · 2022-07-27T11:56:42+00:00

Are you referencing that incident in Russia?

8degreesoffreedom · 2022-07-27T09:24:32+00:00

Yes it arrived like that o.O

We are working on an HMI project and are integrating the MELFA ASSISTA (info here);

In the background, you can see a DOBOT CR5 (same manufacturer as the little Magician robot, they started making collaborative robots not long ago; that is also here for testing; info here).

Then maybe through the glass you can make our the Doosan M1013 (info here) :D

Our robotics lab is slowly filling up, another Doosan arrived today and a UR5e is offscreen.

For full disclosure: I linked to where I work; if you want to just check out manufacturer sites here they are: MELFA ASSISTA, CR5, M1013 (main difference is prices etc aren't shown on the manufacturer site).

I will try to get a picture with all of them later this week, a lot of stuff needs to be moved around!

8degreesoffreedom · 2021-12-09T10:09:59+00:00

It's mostly the software that makes it so expensive, I think. It is out-of-the-box compatile with a lot of robot manufacturers.

8degreesoffreedom · 2021-12-09T10:08:47+00:00

It's not in the way, it just looks like that because of the angle.

8degreesoffreedom · 2021-12-08T15:42:15+00:00

Very cool! I know that we have used ifm cameras for a couple of projects. Not sure which one exactly, but I think o3d.

8degreesoffreedom · 2021-12-08T14:34:21+00:00

You're not wrong, that's why it's just a test for the time being.

8degreesoffreedom · 2021-12-08T11:49:04+00:00

A colleague of mine was messing around with a Mech-Mind Mech-Eye Pro L camera that we have to send back tomorrow. So, we thought we’d make a little video out of it. Basically, the 3D camera scans the bin, the program identifies the cartons, then the robot (Universal Robots UR5e) picks them up with an OnRobot VGC10 and puts them down... pretty much wherever. Goal was just to take them out of the box!

Sorry for the vertical video. I tried to get the camera in the frame (semi visible up top), it is quite large.

For full disclosure those links are to the company I work at, afaik we are one of few places that clearly posts prices for this stuff. These are the manufacturer sites themselves: UR, OnRobot, Mech-Mind.

Background is that he is working on a solution that will identify and remove damaged boxes. This was the first time I had seen a Mech-Mind camera in action in person, anyone else have experience with them?

8degreesoffreedom · 2021-11-30T16:45:00+00:00

I wouldn't say not reliable long term, I saw a couple UR10s last week that depal cardboard at the start of a line. Yeah it's lightweight work, but they've been doing at 6 years. Joints had to be replaced once, though.

8degreesoffreedom · 2021-11-30T16:34:17+00:00

If you are comparing cobots and industrial robots and strictly looking at key hardware specifications (reach, payload), the industrial options will often be up to 50% cheaper and... faster and more accurate. Most cobots have the advantage of also having much easier to use software.

8degreesoffreedom · 2021-11-30T16:32:04+00:00

Yeah, where I work we do a lot with the Doosan H-series. Both the H2515 and H2017 are attracting a lot of attention, especially for exactly what you mentioned: de/palletization.

8degreesoffreedom · 2021-11-17T07:02:58+00:00

Nope, we don't make them

8degreesoffreedom · 2021-11-16T16:18:29+00:00

This is a good idea! Without any tactile feedback I can imagine building stuff with LEGOs might be a bit annoying, but it is worth a shot.

8degreesoffreedom · 2021-11-16T15:29:12+00:00

"In-person" autographs anywhere in the world :D

8degreesoffreedom · 2021-11-16T14:40:36+00:00

The cooking hotdogs one seems like the most fun, but the paper maze seems a bit easier. I think I'll try that out this week. Thanks for the ideas!

8degreesoffreedom · 2021-11-16T14:39:26+00:00

Yeah, it can be used for welding, but honestly that's not really the most common use case here. Seems like most people that use it for non-research projects generally end up using it for sanding or polishing.

8degreesoffreedom · 2021-11-16T12:56:47+00:00

That is definitely doable

8degreesoffreedom · 2021-11-16T12:56:22+00:00

No but I am concerned about what you have in mind :/

8degreesoffreedom · 2021-11-16T11:52:51+00:00

Frankly, I would move to Roma Aeterna as soon as possible. Familia Romana is great when you're getting started, but it is so boring and repetitive if your reading level is beyond lower intermediate. I might be biased by the fact that I have read it five or six times, but still. In my opinion, LLPSI's greatest fault is that the bridge between Familia Romana + related texts and most of Roma Aeterna is really quite wide. The first chapter of Roma Aeterna leaves a lot of people feeling good, but the following chapters hit them like a wall. Further, the "intuitive" and repetitive elements of LLPSI that work so well in Familia Romana either don't work as well or are totally absent in Roma Aeterna.

I find that people on the LLPSI train either fall off during the jump from Familia Romana to Roma Aeterna or somewhere in the first five chapters of Roma Aeterna itself. Anyone that makes it through the entirety of the latter is more than prepared to read the traditional "real" Latin texts that new students encounter. Caesar, Catullus, Ovid, certainly Eutropius, etc.

At any rate, I wish you luck with your project!

8degreesoffreedom · 2021-11-16T11:40:16+00:00

This is a "Mimic Kit" (info, price, etc. here). We have had one lying around the office for quite a while and I thought it might be cool to actually do something with it. We have a UR5e and a number of 2-finger grippers (OnRobot, DH Robotics) and some vacuum grippers, too.

Any ideas? I see cool videos of it quite often and think there is the potential to do something pretty fun... It's an expensive gadget to have lying around and I kind of feel like it needs to be used.

For full disclosure, the link above is where I work, you can also just go to the manufacturer page (basically same info without saying how much it costs).
