Stand Holder for Torso

This thing was made for my previous torso and someone on the forum requested it for download.
Unfortunatly the torso has been redesigned since then. 
So tonight I pulled myself on the front of the screen, launched Blender and modeled this new part.
Never tried it though, so use it carefully.
It's the green part on the picture, handy stuff, you can now set InMoov on a broomstick.
Ahh, I wish it could already clean up my shop!!

Torso for InMoov on Cubehero

Hi all,
The torso parts, which allows you to make the junction between the two shoulders and the neck, are uploaded on Cubehero for the moment.
I'm trying to see how that works.

Of course for now the site doesn't look as fancy, compared to Thingiverse, and has some problems to be solved. I can't remove a part that was uploaded by mistake. (It's the one with no thingiview image)
But the guy that runs it is very responsive.


For the building of those parts, check the Tab "Assembly help", it is explained with the shoulders construction. 

When I will have a bit of time I will add some sketchs.

My troubles with power supply are completly gone since I use the batteries. Remember in a previous post, I had jittering servos which would move erraticaly. 
No more of that, I can really focus on the next parts. 
The good news about battery powering, is that it makes InMoov independant for the days he is going to walk around.( Well if he ever walks around...)
One battery is enough to power all the servos, I had bought three, so I'm using all three.
They are very cheap, I found them on a special offer for 8 euros each.

This is great! I found it in my street, someone had dumped a desk chair with wheels, although it is forbidden to dump in the streets.
At least it made a happy finder.
I removed the seat, added a metal tube I had laying in the workshop. It's a super stand for InMoov until he gets his own wheels or feet.


Shoulder InMoov for New Year, 3d print it!

Happy New Year to all of you crazy robot fan and builders!
I have a little present for you ready to download. You should be abble to build the shoulder with succes if you follow the tutorial I am going to post in the Assembly Help tab.

I know some of you have been waiting, but I had to redesign and reprint this a few times before to finally get it the way I like it. My initial design and prints didn't have enough DOF, and my second design was too large to stay in a human size range. I tried to use parts of the bicep, but came to realize there was to much pressure/torque on the worm gear, so that also had to be redesigned.

Of course it could be much more improved but I don't have enough time and money for to do that. For exemple, the printed screw threads could be replaced with linear actuators, making it more accurate and strong. But I try to manage my wallet for this project, and I know a lot of you are in the same kind of position. So if you've got a thick wallet, you can replace those parts fairly easily. I have made the space for it and added attachment holes for to be adaptive. The others with a smaller budget can print and play, if it breaks, well, reprint. Or get them printed by Shapeways in stainless steel for a reasonable price.

These are some of the broken and rejected prints I didn't throw away.

But be reassured, I've had these parts on for several weeks now and I have been making them run already quite a few hours, sometimes mistreating them badly, and they are holding. The main breakage I had, were during the implementation of the servos speeds and positions feedback, plus a problem with my power supply, which would make my servos act erratical. If they go further then the limits, they break.

Anyway, like I say following the tutorial should make it easy to construct.

I also need  to upload the torso because the tuto concerns it too. My problem is that I'm not finished with it.
You see I need to think of the vertebra attachments to the torso and that might change a bit still.
We will see...
