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!

You want to build a walking robot this is a good one.  This robot will be in my future....

I have a similiar robot to that I built with synthiam but never really got walking well I guess I need to go back to it.

I am a fan for printing an inmoov at .64 scale. It's the perfect size as normal size servos are .64 the size of the large ones an inmoov primarily uses. You will have to do some design work though to pull it off.

Here's mine although I went a different way on some of the design towards the end.

Thanks for chiming in Perry! You definitely took the scaled-down inMoov in a different direction than I was expecting!

I think I'm going to stay with the life-size scale as I don't want to do too much redesigning and I like the wow factor of the full-scale version.

There will always be a place in my heart for the 0.64 scale version though:D

Hey Jer, excited to see what you come up with on this project! You can trust what ever Nomad says as I am using his Imoov head and neck for my West world gunslinger project! He knows his stuff with 3d printing!
