Hi Gael, I am from India. Can you please tell me what filament have you used (ABS, PLA, etc) and total of how much filament have you used for making the inmoov.
Best regards, Subham.
Hello Subham and welcome! You can find these informations in:

@markus Love your InMoov base however looks to be rather expensive to buy or build one?
Hello Juerg, Markus had posted all his mecanum wheels design here: http://www.thingiverse.com/thing:1116924

is anyone is there who is making INMOOV in india ?
There are not many in or around India. See here: InMoov World Map https://goo.gl/maps/G9jcZJjDciB2
I have sent 8 times Nervo boards to India. Five of those orders were dual Nervo Boards with components, so I suspect 5 other InMoov getting built in India.
Hello Gael & Akash.. I am virendrasinh from Gujarat, India. I am 4th(final) year undergraduate student of Engineering. I am also making INMOOV(awesome) robot(started before 3 months). I will upload post soon… Thank You Gael for everything making Opensource.

Finally the Arduino fits well in the updated FingerStarter_Kit. (see picture) The new pulley and adapter for the small servo also fits well.
I need to say….. I’ve found a other servo, which is a bit bigger and has 10gr more weight The good thing is, a standard pulley like Futaba will fit. And it has 2,1kg more torque as the small…[Read more]
Very cool Marten! Once the finger is assembled, a little video will be nice to see!
Hi Gaël,
Thanks and yes, when all is running fine together…. I will share a “little” video 🙂 I think this will happen, when I get the new servo’s because of the fit to the pulley’s. I hope to get them next Tuesday.
when trying to reduce the forarms weight – did you experiment with getting less weight from the printed parts too? Just had a chance to look at a fiber enforced part at an exhibition. It had a thin layer of fiber on top and bottom of the part (needs 2 extruders) but showed impressing strenght.
Hi Juerg,
I hope to save some weights with the new servo’s. They have three times less weight then the servo’s which I’m using now. And the servobed will be smaller.
About the printing parts. I’ve done one finger with Carbon fill and is very lite. I’m only not sure enough, if this is strong enough !
how did you print the carbon item? Layer size? Perimeters? Fill? what tensions are you using? did you try to reduce friction of the tensions?

We are building an InMoov at Shipley College in the UK. The aim is to have our level 3 Software Development and Games Programming students program it as part of their coursework on object oriented programming. So far we have the head and most of an arm – the students are going to print and build the rest over the next few months. Here is a short…[Read more]
Great video!! Let us follow the progress by posting timelapse if you will. I’m always glad when InMoov is being built by students.
The students are going to record their progress on a website they are going to build – I will post a link to it on here. Thanks again!
Great!

Proof-of-concept for adding force control/feedback to Servos using the InMoov Finger Starter.
Modified the kit to accept an FSR. The servo is modified and mounted that it can slide a bit in the direction of force. As the finger tightens, it forces the servo case against the FSR, which is then read. Basic force control written in Arduino as proof…[Read more]
Hi !! Great news. I was working on something like this , maybe you use the same components ( hall effect ) : https://www.youtube.com/watch?v=vNmCTcmA-JQ&feature=youtu.be . But I never find time to impletent it
Hey Anthony, I think Joel did it will hall effect sensors, he’s already integrated it with the hand. https://www.youtube.com/watch?v=50necbOJpME . It shouldn’t be too hard to modify the servo bed model to apply it to the entire hand. A friend of mine is also experimenting with velostat as a pressure sensor. Might be an even cheaper way to get…[Read more]
simply fantastic! Looks very responsive. Will you share more details about it and the code to run it? As you say it’s controlled by the arduino some more cables to route to the hand or are you thinking about a separate nano controlling each hand?
Great project Alan!! As mentionned Joel had done a great research on the hall effect sensors. The FSR are not very responsive unless pressure is applied. How did you manage to fix the two kapton copper wiring? Won’t they brake/tear after long term running?
Hey Gael, Thanks!
These FSRs are the exact same ones that many people are using for autolevelling 3d printers, I haven’t heard of them breaking under similar use. Here’s the exact ones that I’m using. https://www.sparkfun.com/products/9375
Because of their placement next to the servo housing they end up being very sensitive relative to the…[Read more]
Thanks for the extra pictures, it gives a good idea about the process! What is nice with this setup, is that it avoids having cables running within the fingers. (Which is not easy to work with); The servo bed would need a bit of modfication, but all together, it’s not so much work and it could even be applied to forarms that have already been…[Read more]
right, big thing, no need to take too much apart. My question however is unanswered – I assume the finger tester code reads back the status of the FSR and repositions the finger? This will need 5 more cables from the forearm to the arduino and a modified finger service to take this into account? Or am I (once more) wrong again? Tell me I am…[Read more]
The Nervo board can handle the sensors. In my tutorial I explain how to set an extra ribbon dedicated to the sensors. Inded the service will need to be adapted which I have been waiting for ever since I have added the sensors in the fingers. 🙂 Time to take that in a serious matter!
Right, your finger sensor has been in place for a long time but it just looked too fragile to me to build it into the hand. And as you say it never got respected in the servo service?
I hadn’t seen this, but there’s a guy out there by the name of Clement Vella who has also worked out a solution using FSRs, not sure if they’re hand made or not, but he a sensor for each direction of force and integrated it into the pulley.
His video also confirms one of my questions, that maybe applying PID to the control code may work better…[Read more]
This is what I’ve printed yesterday, it needs some smalle updates to fit the Arduino better 🙂 When this all fits well, I will share this @ ThingiFirse including the new servo pulley !
Hey Marten, that seems like a great modification. I have a question if you have a moment, since you designed the nerv boards. I have one servo (Rt arm omoplate), which when connected to the nervo board, gets hot and eventually burns when connected to the nervo board. The servo works just fine on a tester etc. I have seen in the tutorial, the…[Read more]
Hmm, it sounds there is something else happen with your servo connection. If there is a shortcut between the Arduino shield and the small PCB, the flat-cable will start getting hot ! Please double check if there is no connection between servo outputs 10 and 11.
If possible could you send me some pictures from your boards?
Thanks for trying to help me. I sent images via pvt email.
Hello Jaideep,
Please read this post from @juerg
An error in a script and an unreachable neck position – just burned another HS805BB so badly, it burned a hole into the case and I can still smell the odor of death when entering the house.I have added now readjustable fuses for all of my large servos (PFRA 160, Reichelt.de).Hope this prevents future smoke!- juerg (@juerg) July 24, 2016
Give it a try and see if this will solve your problem.
@juerg Which servo’s are you using in combination together, which gives you this “Jitter” problem ? Do you have a oscilloscope ? If yes, could you make and share some screenshots, when you…[Read more]

Wooouii, another InMoov alive! Red yes? What’s his little name Vlad Dracula? You could add these fangs I designed many years ago: http://www.thingiverse.com/thing:15715
Jajajja. Is not bad idea. I think it…
Very nice prints and assembly!
Thank you very much coming from you is quite a compliment. It is a project that I love. It has given me a lot of hours of entertainment for mounting the mechanical part now this entertaining me much putting on electronic slowly and I sense that will give me many hours of entertainment programming and fine adjustments. Thank you very much for…[Read more]
Today I’ve printed a first updated FingerTest plate, including a spring which I’m using as a mechanical Servo-Safer. See pictures…. And tomorrow I hope to test the new 2.5kg servo’s, this depends of the servo’s will be delivered 🙂 I can’t wait….
Hello Marten, Very nice module for a Finger Starter!!! There is no doubt that the servo of 2,5kg will work because even a small SG92R works. With the Finger Starter there isn’t much friction. But such servo will burn for sure if used in the hand. The friction is far greater in many ways in the hand, that is the reason even a MG996 of 12kg Torque…[Read more]
The spring main function is to safe the servo mechanical (there is no direct blocking anymore). And including my servo pulley’s, the finger “close position” gets a smaller arm length ! So this safes a lot of energy use from the servo, when the finger is in his “close position” 🙂 I’m almost sure this spring setup is enough to hold a…[Read more]

Hi akash, Why do you try to use such an old version of MyRobotLab? OpenCV is missing something in that old version. Try with the one here:

Fulvio Paganoni posted an update 9 years, 3 months ago
Woooi nice finishing aspect! Aren’t the eyes a bit too close from each other? Or maybe it is not totally finished.
Hi Gael this is only a probe for fitting all, is no finished
Really impressive! How did you get such a great finish?
hi shipley for finish i use 50% acetone 50 % abs, for have a similar abs paint that i use with a brush, when the layer of abs is dry I apply another hand of abs, until the surface is smooth. after work i spray with white paint.
Okay understood about the probe testing. 🙂
Hi Fulvio This gives me something new to try, thanks.
Hello InMoovers,
Last weekend a good friend and me where asked to come to the “Mini Maker Faire” in the Netherlands. http://www.eindhovenmakerfaire.nl/?lang=en We where there “as builders” to talk with people how like to build something like InMoov. At our stand, we shared some more projects from https://www.wevolver.com/home/

Hi Gael (@admin), I saw that you had designed some legs but still not finished with them. They look fantastic! I was hoping to put legs on my robot for visual purposes (not functionality). Is it possible to share the .stl files so we can print the legs for our inmoov? If not, I completely understand. Thanks in advance!
Hello Sean, Ah yeah, I know, these legs make a lot of jealous. 🙂 I don’t plan to share yet until I’m through with them, too many things to modify still.
how to remove this error shown in red line at the bottom of the pic
Go to myrobotlab.org and ask your question, they will be able to help you out.
You need to correctly specify the path in the script: gesturesPath = “C:\Myrobotlab\ProgramAB bots\gestures”
aimlPath = “C:/Myrobotlab/myrobotlab.1.0.1412/develop/ProgramAB”
