I have been working on the design and motorization of a new head.
This new head is compatible with the three piston neck and the rest of the InMoov body. It has a silicon skin made in some 3D printable molds and can do face expressions.
Here is the female version:
This is the male version:
This is the male version in motion. For this test I have used some bad SG90 servos which burn and are awfully noisy.
I also have implemented those face expressions into Myrobotlab, so it is pretty easy to test and have fun with it.
To launch all servos for the i2Head, start the head via InMoov UI, then a toggle button will appear at the left bottom. Clicking on that button will allow you to start all necessary servos. You will need to calibrate them and connect them to controllers and PCA9685 according to this spreadsheet.
Note that the i2Eyes are synced to the original eyeX and eyeY.
Also the i2Eyelids are synced to the original eyelids servos.
This will probably change in the future, but for now it allows to use standard gestures to operate the i2Eyes and i2Eyelids.
Here is the listed names for the new servos:
## the eyes
i01_head_eyeLeftUD
i01_head_eyeLeftLR
i01_head_eyeRightUD
i01_head_eyeRightLR
## the eyelids
i01_head_eyelidLeftUpper
i01_head_eyelidLeftLower
i01_head_eyelidRightUpper
i01_head_eyelidRightLower
## the eyebrows
i01_head_eyebrowRight
i01_head_eyebrowLeft
## the cheeks
i01_head_cheekRight
i01_head_cheekLeft
## the upper lip
i01_head_upperLip
## the for head
i01_head_forheadRight
i01_head_forheadLeft
You can find all stl files in the InMoov site STL gallery:
https://inmoov.fr/inmoov-stl-parts-viewer/?bodyparts=i2Head
https://inmoov.fr/inmoov-stl-parts-viewer/?bodyparts=i2Eyes
Molds are now available in the STL gallery. The size of the molds are big and require a big print area. Check if it fits your printer prior starting building the head. Standard 220x220mm bed Size will do the job.
The silicon reference is Smooth-On 00-10. One skin requires about 500Gr You can color silicon with oil paint or pigments. You can also add flocking to give it skin touch. Because skin color is very light and slightly transparent, you only need to add a very little amount. Mainly white, then some red and a tiny bit of yellow.
