Bicep for Robot InMoov
by hairygael, published
Here is "InMoov", the robot you can print and animate. You have a 3D printer, some building skills, This project is for you!!
Don't be scared or intimidated, I started this a few months ago and didn't even know what was Arduino or a servo motor!
Start with printing the hand like I did, and go on the rest if you feel.
Well it's been a fun time creating this bicep, I have gone through quite many prints for to finally release it.

This video isn't actual, I have modified many parts since then:

THIS IS A WORK IN PROGRESS FILES MIGHT STILL CHANGE.
All parts are designed to fit on a 12x12cm print bed, just like the hand.
I have printed all parts in ABS.
With 0.5mm thickness for most parts.
Also most parts have an infill of 30%.
Except "pistonanticlock", "rotwormV4" was printed at 0.4mm with a 100% infill.
"rotwormV4" is the only part printed with support.
Most parts are the same for the left and right arm.
The parts named "leftXXXX" are for the left arm, easy to figure out...
Print one of each part.
Print two of "lowarmsideV1", "higharmsideV1"
You also need 2 Hitec HS-805BB servo.
A little bit of cables.
Update 21/09/12 A step by step Instructions uploaded on the blog
Update 24/09/12 Something went wrong during uploading "pistonbaseV1", you should use "pistonbaseantiV1". Sorry for this mistake. Thanks to 1Robotmaker for the comment.
Update 07/10/12 Uploaded the covers for the bicep + a simple movement sketch for your Arduino seen in the Part8 video.
Update 31/10/12 RotwormV4 is now used for the left and right bicep. If you are building a right arm, you need to inverse the green and red wires on the potentiometer. See blog for more info.
Update 03/01/13 I have uploaded the shoulder parts.
Update 02/03/13 Modified "RotGearV2" to "RotGearV3" teeth are now a bit smaller, avoiding the risk of touching the innercasing. Also modified "RotWormV4" to "RotWormV5", I rounded up the entrance of the worm, for better printing finish. Thanks to Brian for the suggestions.
Update 07/07/14 Modified "RotGearV3" to "RotGearV4" teeth are now angled with openings within the gear to allow cables to run through. Also the external surface of cylinder is smooth finish.
Update 21/10/14 PistonAnticlock, PistonBaseAnti and HighArmSide to V2 version. Bigger section diameter for better resistance to torsion.
