I've designed a new neck mechanism for InMoov to add a degree of freedom. It still needs some fine tuning but you'll get the idea.

Thanks Bob. I am about to reprint my head and will be doing this. I really appreciate you doing this.

Tanks Bob, you did a real nice and bright improvement.
It makes the head movement realistic and will allow to communicate a wider range of emotions.

Question, is it only me?
When I open the stl files in my FlashPrint or 123 Design software the part shows itself as about 1/25 of the real size.

Bob, What size servos are your stl's designed to use? It looks like the standard EZ-Robot HD servos. Can you post a photo of how they are connected to the upper body?

Thanks

@ David
Could you open one of the Bob's stl file from thingiverse
http://www.thingiverse.com/thing:845793

and check if the file opens at a normal size?

In my case it looks very small when i open it with my printer SW.

Correction

Forget about testing the file, I have just realize my SW was converting inches to millimeter. It is fix now.
sorry

I opened them in netfab and they appear normal. let me try from simplify3d.
#27  
These are in inches format instead of mm format. That may be the issue you are seeing.

You are right, I just realize and have adjust my SW.
Tanks again

@Aerius, I'm not sure why the file opens that way. I guess you will have to scale it up. Use this for a reference - The cylindrical part of the Neck Joint Lower part should be 1.2" in diameter. Get this part scaled right and scale up all the other parts the same amount.

@Dave, The servo holder will hold the HD servos from Ez Robot which is basically the MG995 or the HS 311 or any servo this size. There is one photo on thingiverse that shows the servo Pivot in place. The photo is taken from the back here is another one taken from the front. It's hard to photograph. Drill a couple of holes in the mount and attach to the frontside of HomePlateBack.

Thank you Bob. I will be printing these tonight and will let you know if I run into anything weird.

Thanks again!

Great, let me know how they turn out. Right off the printer the parts will fit very tight so little sanding of the Neck Joint Lower part will be required. I did this so the parts wont have any play in them. Grease all the joints.

Just for the record, I don't know why Anthony posted a picture of his latest render on this thread, it really doesn't have much to do with the thread. It is not a remix of a design by me but rather a remix of the original design by Gael Langevin the creator of the InMoov robot. Anthony's design will not fit on my modification unless it is modified. I have asked Anthony a couple of times to remove it from this thread - but he doesn't want to. I just think that comments made on a "Project Showcase" thread should be about the project being showcased!

Ok one more kick at this! This part -Throat piston V2 ( from InMoov website/downloads) I referenced was designed by Gael Langevin. @Anthony, if you are going to leave your design on this thread, please change the attribution for the design you remixed to Gael Langevin.
Thanks Buddy

@Anthony? What are you doing dude? This is Bob's thread... he doesn't post his stuff in your thread(s). I think you should have some respect....
#37  
Hey Bob. I started printing this but had to abort it. I realized that I didn't have enough filament to complete the print. I have more on order which should be here tomorrow. I plan on starting the neck and head again tomorrow. I will let you know the results.

@ Bob,
So far so good, I have the upper and lower neck joint done and they fit perfectly,

I'll make a short video when everything will be fit together.

Regarding Antony's modified Throat piston V2, its modification looks nice and is a good idea, except he should reference Gael Langevin as the original author.
