Stefan Ekstam – InMoov

Stefan Ekstam posted an update 7 years, 7 months ago

I finally decided that the time had come to finish my InMoov. After some grinding, the hardware is now complete to 98 %. 🙂

After trying some of the most recent versions of MyRobotLab (and failing miserably), I tried the older “Kraken” version (1.0.1723) and things worked a lot better. So far I have bricked two LiPo batteries calibrating all…[Read more]

how can you complete the legs with only 2% left???
be patient with MRL – switching to an older version was a good move. Wait for Manticore – I hope we will see that within the next 2 month’s

  What is Manticore, juerg? *asks curiosly*
  - juerg replied 7 years, 6 months ago
    
    Manticore is the name of the next stable MyRobotLab release
    - Olli replied 7 years, 5 months ago
      
      Any info on how it is progressing and possible releasedate?

        Hi Olli
        You can see project issues and progress here (you might need a free github account to access it)

If you should ever try, and get stuck, I could probably help you out. 🙂 After my adventure with the almost bricked computer, I’m now an expert on the Lenovo Thinkpad 8. I contacted both Lenovo’s local repair agent, and Lenovo’s official technical support when I couldn’t make the computer respond, but none of them could help, interestingly…[Read more]

Hmm, I meant I have *now* got it working. 🙂

Great! For sure bricking the tablet would be a waist…
I haven’t tried to upgrade my 2 tablets but since it is working fine under Windows 8, I don’t want to take the risk to brick them.

I realized that the Lenovo Thinkpads were no longer possible to buy new in any Swedish stores. Thanks to eBay I managed to get one from Germany though. After almost bricking it by upgrading to Windows 10 in a nonstandard way, I have not got it working. It\’s time to download MyRobotLab and start printing out the new back parts! 🙂

Yes, I remember seeing that a long time ago. 🙂 I will probably let my InMoov keep its chair base until the legs are finished. But no pressure Gael, please take your time. There are many other things that need to be done first. 🙂

Exactly! Chair bases of the world, unite! You now have a purpose!

Ah, you remember that. 🙂 I actually got another printer just like the one that was damaged, and then I took a chance and sent the broken one for repair. Amazingly enough it was totally repairable, so now I have two Flashforge Dreamers working for me. 🙂

I just visited the InMoov website for the first time this summer, and realized that Gael had actually updated quite a few things. Nice! 🙂 Naturally, I restarted my dormant InMoov project and celebrated by mounting him to his very own chair base.

brilliant, i knew i was hanging on to that broken chair base for some reason. Now i know what it is!

Nice to see that you have come that far with the build. I was a bit worried about the 3D printer fire.

I use the same chair technique on mine. I welded a section of pipe to it to bring him up to normal level. Slides right into Gaels mount.

The chair base brings me back to one of my old post:

I had to wait forever for my Chinese fishing line to arrive, but once it arrived I got going again. Now the left arm, hand and bicep are finished, except for the fingertips. Everything works as it should with the Arduino.

Unfortunately my 3D printer has been destroyed in a fire, so there might be some time until I can continue with this project.…[Read more]

Gael Langevin replied 8 years, 10 months ago

Beautiful!
It is a shame and sad to hear about your printer. I hope you got an insurance or some options to get a new printer.
May 2016 help you for that!!

Ah yes, I was afraid that carving of the plastic would be a problem. I\’ll use my 0.4mm for the simpler finger tester then, just to be able to test something. 🙂
Quite impressive that the hand could do that much work without breaking. You\’re clearly in the industrial quality segment here. 🙂

Yes, I have followed your recommended settings fully. I’m using a FlashForge Dreamer 3D printer with ABS, and this is the first time I have had a problem. I have now reprinted the fingers with 3 shells instead of 1, and I’m ready to retry the drilling later today.
I’m impressed with the quality of the InMoov model. When assembling the wrist…[Read more]

Awesome, nothing better than your own settings!
0.4mm will do the job, but might carve in the plastic after a lot of usage.
One of the InMoov hand I made was exposed in Paris Tokyo exhibit for nearly two months working everyday from 10 AM to 12PM, the 0,8mm braided line didn’t carve in the plastic, I was pretty surprised about that.

Report from the trenches: The right hand is coming along well. Today I had my first shortcircuit which caused a minor fire on my desk, but everything went ok in the end. Better not get too sloppy when working on a project like this. 🙂

I will have to reprint the fingers, since they tend to break far too easily when I try to redrill the holes for…[Read more]

Gael Langevin replied 9 years, 2 months ago

Short circuits even with low power can set fire!!
I’m glad you got away with it!
These (below)are settings I use for to print the fingers, but you might want to go with a 100% infill depending on your material and printer.
Print wriargeV3, wristsmallV3,thumb4 with an infill of 30%, 3 shells, best with no support, no raft.

Most parts printed for the right hand and wrist. Tomorrow my first batch of servos should arrive from HobbyKing. Managed to get one Arduino Mega today, and tomorrow I’ll hopefully get most of the screws. Fishing line has been ordered on Ebay, but it won’t be delivered until late October, unfortunately. It seems my printer, a FlashForge Dreamer,…[Read more]

Stefan Ekstam posted a new activity comment 9 years, 2 months ago

Thanks for the tip! I will print the Servobed to check this as soon as possible. The servos have not arrived yet, and the final parts of the right hand and arm will be printed this weekend, so I\’ll just have to hope that the parts I have printed so far will not be completely unusable… I\’m using ABS by the way, since that was Gael\’s recommendation.

Hi Stefan. Depending on your printer and the material you use, you may have to scale the parts. I suggest that you start printing either the Fingertester part of the Fingerstarter or the Servobed from the Hand. That way you can test how well the servos fit. If they don’t fit, the use the slicer to scale the object so that they fit. I print with…[Read more]

Just got going with the InMoov. My 3D printer is working day and night printing the right hand and wrist parts. Lots of servos ordered from HobbyKing. Just ordered two Nervo Boards from the InMoov shop. I hope to have both arms printed when they arrive. 🙂
