You could always make your own stepper driver win an Arduino Nano that is controlled with a PWM signal and add a pot for position feed back

What spec Latte Panda are you running?
I waiting for my Latte Panda Alpha to arrive, not due until May.
I am running mrl on LattePanda 4G/64G. It’s a bit laggy when starting up but runs fine when using it. I also use their touchpanel 7”.
A lot depends on how powerful your computer is, some people have used two computers, one for the object/facial recognition while the other is used for object tracking and the rest of the Inmoov.
For a beginner in the system you can get away with just the one.
Let us all know how you go with these, it looks good
I have a few of those servos fitted to my Inmoov robot Fred, that work a lot better than the MG966R
You will have no regrets there

I had some not so nice joins between parts after a glue failure, so I hid the ugliness with some nice red paint.
I sanded starting a 80 grit on the belt sander (Don”t do this, it melts the plastic)
I worked my way up the grits to 400 grit, hand sanding.
Then used some high gloss enamel paint.
The result were quite reasonable.
I would not suggest…[Read more]
This is awesome,
How long before we start to see the files for the different parts?
I am very interested in the files for the feet and ankle drive system.
Well, I am waiting for some components from AliExpress which need to be tested before release. Just for info this is already my third knee design, which all three were pretty different. R&D takes a long time and my problem is that I don’t only work on the legs.
beautiful advanced gael.

I’ve had similar problems, and more recently I was unable to upload the latest photos of Fred’s foot I just printed, however I had an internal server error when going to the album to upload.
@mindless, I too have posted a picture with no errors and then thought maybe it did not post and reposted and still not see it. I logged out and still not see my posts, cleared all cookies and started seeing them again? But I’m still not sure way.
There is a function within MyRobotLab (MRL) to send email
There is no reason why you can’t add this functionality to your robot, once you have done that, Please let everyone know how you went about it!
Have you worked out what bearing sizes you need yet?
and have you uploaded the stl files yet?
Curious minds beg to know….
It looks good so far.
Hay Ray,, Sorry for the late reply but I just noticed your message which is weird,, I’m sure it wasn’t there before– ,,, anyway Han’s Tracked down the Main Bearing a while ago
Main Bearing is – 45mm x 55mm x 6mm – the small bearing is 8mm x 16mm x 5mm which is slightly smaller than Han’s bearing,,, I’ll be using the 16mm x 8mm x5mm in a few of…[Read more]

I’m looking forward to seeing it walk unaided… 🙂
lol, I look forward to seeing it *stand* unaided 🙂
Nice work Acapulco ,,,, I see you cut the originals files up for smaller printers ,,, nice work — ,, ‘Bartods” done a pretty good job of replicating Mr Gael’s Artistic style which wouldn’t be easy,,,,,
Yes, nice design work by Bartcam and also in keeping with Gael’s original design goal 🙂
FYI, Bartcam has uploaded some new parts on the thingiverse page 🙂
who is Bartcam?
Hay Perry,,, here is “Bartod” Thingiverse
Bartcam is aka Bartods 🙂
To my knowledge, there is no complete design for legs yet, Bartods appear to be the furthest along so far.
But is still under development.
Once he has completed the mechanical components, the programming will start and will also be a big challenge.
I know that others are also building his designs and will…[Read more]
I used 3mm line trimmer line from the hardware. its cheap and works well
That’s a great idea,,,,, I found knitting Needles in the $2 Shop,,,which are 2.8mm and $2.50 a set,,,, I didn’t even think of pulling a bit of cord off my whipper snipper,,,, lol
Oh Yeah that’s right,,, I kept with the Knitting Needles because of the Type of Plastic—It’s Extremely hard you can use on Micro Lathe or Drill Press for Shaping ( not just for finger pins) I’m 99% sure it’s Acetate plastic,,,,
Like Ray said , I bought trimmer line used in a weedeater and it worked really well
Where do we get the nuclear power source? That will solve the battery issues 😉
I have the flux capacitor mounted behind it.
Thank you Perry, down loaded them now and will fire up the 3D printer in the morning. Like the look of your robots back as one piece, did you print that as one piece or did you join multiple pieces?, looks very good.

When a user needs help, it helps if there is only one type of robot to support.
That way there is no confusion and a lot of people can help you.
Once you start to go down a different design path, there is not as much help so you have to learn more yourself.
This not discouraged, but in the beginning, it is advised you stick to the standard list of parts.
You are soooo right, I forgot about that.
Will look into it when I get on him 🙂
Maybe even some gold lightning emblems on the side of the head 🙂
Very nice, Simon says Flash!

Just a splash of red paint, cause everybody knows, red goes faster….. ;=)
Remember racing stripes can make him self aware.
The HAT on the PI is the Adafruit 16 Channel servo driver. Also breaks out the Pi Header and is where I grabbed the 5V from to run the other Pi.
It is possible to fit the third one and then i still have to work out how I want to split the processing load across them.
As Gael said somewhere on this site, the RPi even the Model 3 still is not quite powerful enough, but they are cheap enough to add multiple so speed up processing, paralleled processing if you will…
You could put one PI in the body to connect to the Kinect or just give him a gut feeling. Nice HAT on the PI.
2 out of 3 Raspberry Pi 3’s installed in the head.
That’s alot of pi! Is fitting a third in there possible? Looks great though, very clean setup in that limited space.
good job, you can also find less hole intense versions of the face on thingiverse

If you have a look in the STL Parts Library located in the Gallery.
InMoov body parts library :
You need the recommended 3 shells for strength.
Running with 1 shell will reduce the filament usage and reduce the print time.
If the guy said the dimension will be messed up, then he doesn\’t have his slicer program setup correctly.
Most likely over extruding.
Looks can be deceiving, but thanks for the complement.
The shoulder pieces are probably the best parts on the whole robot, I’m more pleased at getting the ribbon to work through the bicep gear.
Some of the earlier pieces had real bad banding, turns out a spacer i fitted to the top of the Z axis screws to reduce the banding actually made it…[Read more]
Because there are so many types of 3D printers and slicing software out there, when asking a question like this, it would pay to list the 3D printer make model and the slicer software and version.
That way someone with the same slicer may be able to help you out.
I printed that part a few weeks ago with no problem on my cheap “CTC I3 Pro B”…[Read more]
The button is labeled \”Add Photo\”
Little bit confusing, but it works
Got to the bottom of the Elbow destruction.
The smaller servos for the forearm were a long time in coming, so i had the larger joints all fully operational and calibrated long before the servos for the fingers arrived.
After I installed the servos for the wrist and fingers, i neglected to re-test the elbow until yesterday, at that point the wires…[Read more]
This video upload is in response to lorn Campbell query as how it works with the Bicep rotate.
My recommendation for anyone wanting to do the same thing, would be to use a ribbon with more than 16 conductor and spit the extra across the power wire.
I used 3 for the servo power 6 Volt and 3 for the servo power 0 Volt, this may not be quite enough,…[Read more]

Fred InMoov first video, shoulder view of Bicep rotate.
Nice and smooth. Your print quality looks really good with no banding.
The cable relative to the shoulder moves in the gap, the cables relative to the bicep are stationary. The elbow piston clears the ribbon cable by a 2 mm inside the gear, gets a bit closer outside the gear on the bicep end but still clears it just.
Mounter 16 channel PWM Servo driver in the left bicep.
Also added a small SMPS buck converter in the power supply line to allow for later increasing the a 12V or higher battery system.
Tripled up the wires for the power supply to cope with the current draw of the servos.
Only need to sort out a connector for the power in the shoulder and…[Read more]
Running a 16 way ribbon through the Bicep Rotator is tight, but it is doable.
Held in place with CA glue.
Next job, terminate each end to where they need to go.
I do like your work, Very nice.
Are you going to upload this to Thingverse?
Coming up on 6 weeks, the Top Stomach parts have been the biggest challenge so far.
Parts were very tight, then one of the wire came off the servo pot, worked during testing, but not after assembly. Bummer.
Have now mounted the servo’s in the left hand, will have to work on the fingers next.
Can’t install the Neo Pixels yet, turns out it not…[Read more]
I am unable to snake my wires through there. The piston interferes. I have them bundled though and might have to unbundle them so they can fit. I am using servo extension leads though and not ribbon cable.
Wow, the cables fit through the gap. What happens when you rotate the arm? The arm cables have always been an issue on my InMoov, have run the forearm & hand in sleeving externally, but the shoulder cabling is still a mess.
Great pictures, looking really good Ray
Your timing is incredible, I have just did-assembled half my robot to start installing the top stomach. In the photo above you may notice the pistons on the table already printed. Yesterday, all the small servos arrived, so I now have the jaw working and have mounted the 6 servos in the left hand.
In a day or two when I have Fred…[Read more]
This being my first post here, I must thank Gael for all his work on this project that he has made freely available and more importantly the foundation of this community.
5 Weeks in the making, it is soooo painful waiting for the 3D printer.
I do have a query, has anyone else had trouble with the InMoov scripts not using the config files for the…[Read more]
You have hit the same problem as I have. The InMoov services are made specifict to use Arduinos. I discussed this with GroG last weekend, and I learned how they can be changed to make it possible to use the type of configuration that you have. The problem with making that change is that it’s difficult to make that change, and still keep backward…[Read more]
