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!
Thank you I thought I have to upload it somewhere and then link it... this is much easier for sure.
Perry there is the base file you asked for: NEW BUTT.stl

always check your messurement if you download a file from TC to your pc . sometimes the messurement are diff with some 0.10 to 0.30 MM.
Nomad 6R, Yes I have noticed that with some parts I have created in TC I wonder why that is?
This Butt part looks good on the Inmoov but you can't use the rods in the legs with it. The rod can only be used below the knee to the foot if you go with this part in your build.
BTW I decided to go with the Handi-Hands in my build I was able to convert the parts for the HS-40 servos and I will also be adding the touch sensors but I need to figure out how they can be connected to the EZB4's I need to see if DJ or Jeremie has any input related to this. The other thing I am doing will be to design a rotating forearm to go with this new set of hands. Then the only other part will be the wrist so I can make him wave so if you have any thoughts on that please let me know.
Once I get things together I will share with anyone who want this stuff.

looking forwart to see your hand . it looks sofisticated . consider all the finger servo's are in the hand , you have plenty of room in the forarm for another servo . i think excample a think plate shape arm inmoove , were you can put a servo in . i always use the HDD from ez robot . and a long gear . most problems are wires , thats turns in the arms from all the tiny servo's so you have to guide the wires away from the turning servo . do you have any drawings or idea ? i think its not so diff and you can use similar like original wrist inmoove . i can help tinkering . i need the stl from frame from your hand .
@smiller29 Worked on the design last night, should be in your inbox!
Thank you guys for all your efforts!!! It is on the printer now printing for the next 2d23h11m....

no worries . its all about learning . and it looks indeed perfect . it would be nice to see how the master did it .
thank you jeremie&smiller29 for the stl .
@smiller29 & Nomad 6R No prob!
While I don't have the time to make a video and show you, I can certainly share the process with you here:
It's handy to have the 3D printing plug-in for Blender installed. Search Youtube for guidance, it's easy to install from within the program
Import your model and switch to "Edit mode" in the top left
Start by selecting and deleting the elements around the hole (delete vertices is best I find but you can also use delete Edges & Faces)
You can look inside the object to make it easier to select and delete elements by using 'Alt+B' to split the view (won't affect your model) press 'Alt+B' again to return to the full model view
To rebuild the elements that you removed select 2 edges (remember to click the edge selection in the upper left) and press 'F' to add a face (forms a triangle) you can also add edges by selecting 2 vertices (remember to click vertices selection in the upper left) and press 'J' to join the vertices. The join feature doesn't always work but when it does, it's great!
Finally use the 'Move' tool on the left side to move vertices outward to make the object more round again
I'm not sure if this is required but I used the 3D printing plugin 'Make Manifold' button to ensure that the whole model was watertight so that it is considered a solid part. Go back to 'Object Mode' and export your STL model
