I'M Going To Build An Inmoov, Any Advice?
Hello, Synthiam community!
I'm going to need your help. I would like to build an inMoov for the first time. I want to take full advantage of the new Quest VR skill that can control the individual fingers of a robot.
I do have experience with building the head and shoulder servos, and a bit of experience operating it. Oh yes, and I have helped build a base for the upper body. Otherwise, I am a clean slate.
I'll be using all the EZ-Robot parts that I can. I will power it from a 5V 20A power supply as I've done in the past (with the super cap mod). I may design an external power board. I like the idea of including pins and switches.
I will be using EZ-Robot prototype high-torque servos any place a HS805BB servo is needed. I might replace some with EZ-Robot HDD servos if they can handle the job, as they are pretty torquey themselves (maybe the neck).
1. I have a head printed already, should I continue going from the head down to the stomach?
2. Should I print the legs or is it a waste of time at this point since they aren't functional yet.
3. Am I ok using PLA, or should I really get into the PETG game? Or PLA+?
4. I read that 30% infill should be used, is this right or should I go thicker/thinner in some places?
5. Should I use 2 shells when printing or is 3 or 4 better?
6. What are good methods for propping up the inMoov during the process.
7. What type of lubricant is best for the worm gears? White lithium grease?
8. What are some of the biggest challenges I'll face? Are the hands quite difficult?
9. Do you recommend a particular Youtuber or inMoov build page?
Thanks in advance for any advice you can give!
I only got as far as an arm and I used PLA and a Prusa knock off. it was not very good. I eventually purchased a genuine prusa i3 MK3S and used prusa PETG and I strongly recommend this path. It is a little expensive but it doesn’t warp and is pretty strong.
I never got passed the arm as I had a lot of issues with the fingers and I am sure it is a newbie problem with garbage servos and I wasn’t happy with the fact inmoov can’t walk.
we really need an open source walking biped robot. James Bruton did some amazing work with his robot x biped and maybe his ideas could be used to help inmoov walk but inmoov is still a very heavy robot.
I using PETG filament also, works best no smell...
using the Ultimaker Cura for settings, slicing etc...
we figured our for our 3d printer: I am using the Creality - Cr 10S pro v2 printer
"glass" bed = 87 nozzle = 237 speed = 20 to 60 max fan off Z = -2.29
no magigoo printing at a slower speed is so much better
make sure you tighten the printer head (nozzle) so there is no play - tighten everything first

@EZAng and @smiller29 Thank you for the advice and information!
From what I've been reading it seems that none of my printers are ideally set up to print PETG. The Replicator 2 would be the closest as it has direct drive but no heated bed. The Replicator 5th Gen printers have a Boden tube inside the smart extruders so I may run into issues running a higher temp, and they don't have heated beds either. The Elegoo Neptune 2S is also a Boden tube (non-direct drive printer), while it does have a heated bed I'm concerned with running it hotter with the PETG filament. I have seen pictures of nasty things happening to Boden tube printers with PETG due to the higher heat.
I think I'm going to risk it and print the inMoov all in PLA since I don't have the capital to buy upgrades or new printers at this moment in time.
Having 4 printers at my disposal does help with shortening the time frame to finish the project. Another positive is that Makerbot printers can print PLA at 90-150mm/s because of their rigid frames so it should speed things up as well.
@Nink I do hear really great things about Prusa printers on TikTok. They seem to be the holy grail of printers, well in the hobby world at least. I feel like if I was serious about printing in PETG I would definitely need a capable printer and would need to invest in something better than what I currently have.
I do like what James Bruton is doing but I'm not a big fan of his style. It seems that he likes to make things oversized a lot of the time and who has time to print everything at 200% scale, ain't nobody got time for that!
I do think he's on the right track with his biped but we'll have to see what Gael releases in the future in terms of legs. For the time being, I'm content with rocking a wheelchair base.
good morn Jeremie,
I also watched some of James Bruton's videos, impressive but out of the reach for most people, (room, expense, items, time to build, Ect.)
He does have many ideas.
However, you said:
The excitement of building an InMoov robot is a great plan for you. Good luck.However, I seem to me as an oversized JD robot. A JD robot can walk with legs and do many things an InMoov can't for testing servos, sensors and controls with ARC. You know better than me all the function a JD robot can perform at a much lower cost. With modifications to JD robot may things can be accomplished.
After building many robots here, storing them is getting to be a big problem in a home when not using them. I don't have a workshop.
Anyway, all the best to you with the build, planning and learning curve, you will experience.
take care

If you haven't started building your Inmoov maybe you should look into the smaller version some have built on here. Can't remember who off hand but I'm sure a little searching it will come up. If I was to build one I would consider at least looking into it seriously. Just a thought.
All my best to whomsoever wants to build an InMoov.

not to mention after your done experimenting with it, with nothing new, (movements or actions) then storing it in your home....if you don't have a work shop is a problem.Herr Ball -
Agree, The InMoov have been done already many times with no new (less then JD robot) movements or actions.But again, all my best to you
