Quarantine has given me time to work on the graphical UI for InMoov in the new version of MyRobotLab (non released NIXIE).
There is still many bugs because the webgui is a BIG work in progress, but you can try it out and see many new features.
Thanks to Astro for all the help and making a tutorial to get me to understand how to work with…[Read more]

We recently encounter difficulties shipping some of your orders from InMoov website because of the Corona Virus. China has recently extended it’s quarantine time. Some components have been held by the customs much longer than usual and won’t probably arrive before weeks.
Therefore I have refunded all orders related to “NervoBoards…[Read more]

Hi Gael, short question. Do you mount the hall sensor in the same way then the copper plates? HallSensor – Foam – Magnet? If not, do you have a picture? Thanks a lot,

I tried to connect the external power source like this, but it seems like the nervo board does not recieve any power…
Only these leds will light up when the Nervo Board is powered but not connected to a PC via the Arduino. Apparently looking at your photo, you do not have these 4 optional leds soldered. (they are not necessary for the board to work, it’s optional.)
Connect the Arduino to the PC and check with a voltmeter, if you have power to the…[Read more]
The servo didn’t response when I try to move it using SERVO_CALIBRATION.bat
Did you upload the MRLComm.ino in your Arduino?
Ok, you have selected the correct COM port in SERVO_CALIBRATOR.bat ?
and the correct pin for your connected servo according to this map:
Yes. It’s a COM3 (I had checked in Device Manager). I currently test on the Neck part, which are pin 12 and 13 only, but the servo doesn’t response. I shows that the connection succeed for the Arduino by the way. I wonder, just maybe, is it the problem of the connection/wiring/soldering?
It’s odd, there is not much that can go wrong with the soldering, beside making a bad shortcut.
Which you would have seen the smoke.
I suspect the ribbon cables in the male headers. Maybe a ribbon cable inverted between the two end points headers.
Do you have a voltmeter?
You can test to see if the power is going to the servo from the XT60…[Read more]
The soldering of Chuah Wei Jie was lose between the XT60 and the power supply.
Anyone have any idea why this happened?
Can you describe how this happens and which version you are using to get this error?
I’m using myrobotlab.1.0.2693.7. It actually happened in a sudden, previously there was no such issue. Basically, I can’t access to any services through myrobotlab.jar (Even communicating with Arduino or access Python), the thing is, these function looks fine if I open it via SERVOCALIBRATION.bat. I don’t know is this a bug or?
So when you launch myrobotlab.jar, you can’t start any service.
But when you launch SERVOCALIBRATION.bat, it works fine.
I never experienced that, and never got a report about such issue yet.
Did you try launching START_INMOOV.bat with the correct configuration for your setup? If yes, did it work properly?
How did you proceed to start a service…[Read more]
The notification : Could not create service Python python pop-up everytime I open myrobotlab.jar. The thing is, there ain’t any problems in launching START_INMOOV.bat. To make sure did the python works, I just simply run a simple line print(“Hello”), it does printed in START_INMOOV.bat or SERVOCALIBRATION.bat but not in the myrobotlab.jar. Is i…[Read more]
This is very odd.
Maybe something went wrong during the install process.
I suggest to create a new directory and install the latest from InMoov site into that new directory.
Hopefully this will solve the problem.
Could you send me the error log by email?
It might give me a hint.

I\’m in doubt in the soldering of nervo boad. Can anyone show the parts that need to be soldered if :
1. I\’m using the same voltage to all sevo.
2. I\’m using the PIR sensor for 5V.
In your case you need to solder like this:
Thanks for the reply Gael. I would like to test the tracking function in mrl by using the eyes only, what should I do?
Hello, use the config files of InMoov and switch the pin numbers from,
-rothead –> eyeX
-neck –> eyeY
This way the headtracking will operate the eyes instead of the head.
Note that the range of movements for the eyes is really less than the for the head.
Hi Gael. I’m trying to connect the Arduino to Inmoov now, but the jaw doesn’t seems to sync with the speech when Inmoov is talking. It can only sync a few sentences initially, but after that it doesn’t seems to have any movement anymore, I wonder why this happen? I had configure and set all the limits for the servo thou.
You can make some adjustments to the jaw using the head config file.
Note that via software the sync is based on vowel and consonant of tts answer. It is not exactly the best way to sync, therefore sometimes it will be finished moving the jaw while the voice is still speaking and vice versa.
Noted with thanks Gael. By the way, in the skeleton_head.config, do we need to change these line of code :
Anyone have any idea how the power supply is connected to the Nervo Board? I\’m lost.
The power supply is connected to the Nervo Board via the yellow XT60 connector.
It is wise to add, between the XT60 and the power supply, a main switch for safety shutdown. The switch can be placed in the side back location.
Is the XT60 connector attached to the Nervo Board by soldering at the port of 5/6V?
Yes it is.
There is a picture showing it in the tutorial.
Dear Gael, in the tutorial it stated that “Soldering the little back connector option 3.3V or 5V to power last analog pins.” in Step 3. If I’m using the same voltage for all servo, do I need to solder this? (I’m not using the 3rd nervo board for the finger sensor as I didn’t build that part)
I am guessing you will use a PIR sensor which requires 5V. The PIR sensor detects human motions, it’s nice to have on the robot.
That means you will solder the 5V to power the last analog pins.
To have all servos working on the same voltage, you need to solder the two main jumpers…[Read more]
I wonder do I need to solder the third red dot (As stated in Step 2, the one at the bottom-left in the picture) if same voltage applied?
Yes if you want to give 6V to the PIR.
But note that it’s a 3 point solder, this gives you the choice, you can give the PIR 6V or 5V.
This will give 6V to the PIR:
This will give 5V to the PIR:

Finally a small step forward.
Too bad it doesn’t fit together, guess I need to calibrate it again. Do I need to polish it using sand paper or anything after the printing?
For the rectangular hole I sanded a tiny bit on the bits that fit in. For the rest I only took off bits that should not be there, it was a (very) tight fit.
Still trying on different calibration, and it still doesn’t fit. I’m using PLA and the calibrator like always exceeding less than 1mm? Not really sure about that. Is the wall thickness that affect the printing exceeding the original scale?
Hi Chuah Wei Jie, I am only printing in ABS-X, sorry my 3D printing knowledge and experience is insufficient to be able to help. Maybe someone else with more experience can help.
My first parts were printed at .24 and didn’t fit so well. I then printed at .15 and they all fit together nicely. Also looked a lot better as finished product.
Mark is right, the lower the layer height the better. I was able to fit stuff together with .3 layers until I got to the worm gears and piston shafts. needed to go all the way to .12 to get those to operate smoothly. always had my infill on 15% for most parts, the “load bearing” parts or parts I thought would be stressed I went up to 30% infill.…[Read more]
Some things I found that help; as noted the higher quality layer height the better the fit, try your finest settings (say .1) and see where you are, then increase until they don’t fit. Use PLA+ if your going to use PLA. Amazons is cheap and works great. (Premium PLA) Print just the way the file is loaded, do not re-arrange the parts. Keep trying,…[Read more]
Morning builders ! The printing process is finally get to start. I\’m using Anet A8 3D Printing. I wonder is there any suggested Start and End G-Code for such machine for a better result of printing? I\’m using Cura.
Great news! good luck Chuah Wei Jie! it is a great journey you are embarking upon. Unfortunately I do not know enough on Anet A8 to help you. But Cura works well for me.
Hi Michael ! I believe it will be. Actually I’m using Cura for the printing too. the thing that I wonder is that I’m not sure the setting of the Basic and Advanced column will provide a good printing result or not. I had uploaded my setting interface in my album. What do you think?
Hi Chuah Wei Jie, I have loaded the setting I am using in CURA for my ABS-X, different but they more or less work for me. With each printer and each print material they will be different. big difference I chose to print in 0.1
Have a good day
sorry Chuah Wei Jie, I meant to say in my album.
Thanks Michael ! I’ll try for both configuration during the printing process.
Morning builders ! If I just build for the upper part (Head + Neck), I wonder how many Arduino Mega does it required?
Hello, yes one mega with one NervoBoard will do the job. It will be called LeftSide Arduino.
You will need to trick the pins for the RollNeck though, because normally it is attached to the right side Arduino.
You can select a different pin in the config files of head. And also select the left board to be the master for…[Read more]
Morning builders ! I wonder how many camera/s needed for the eye mechanism ? Is 1 more than enough?
Hello, Yes one is enough.

I probably need a guideline on how to deal with the nervo-board. Anyone have any idea?
Hello builders. I\’m new to Inmoov but planning to work on it. Does anyone have any suggestion or reference on how to start? Currently planning to build the head and neck part.
Gael recommends a hand to start with. Will give you challenges in printing, assembling, controlling. Afterwards the rest is not so difficult to accomplish but takes a lot of time!
Because I’m having my Final Year Project currently, and due the limitation of cost, building head and neck is the only way for me to accomplish my task and target, hha. I’m searching for someone to guide me and to discuss together throughout the building process.
OK, did not read your request properly. Have you decided what kind of neck you want to build, the single piston up/down or the double piston, which allows to move in more directions?
I have also created an alternate for the head with less parts and holes – https://www.thingiverse.com/thing:1636086
It’s Okayy. Erm, I was targeting to build on the neck proposed by Bob Houston, as the link attached below. I wonder is that a good suggestion? Since, there are a lot of people working on it.
Link : https://www.thingiverse.com/thing:1243403
Wow. That’s cool. I’ll consider about it.
bob huston neck is fine. I built one once not for me but for a friend. I encountered problems with the piston head and the connector to the servos.
Make sure you get stl’s that are proven as working or latest versions.
I also do not know whether proper kinematics exist for the neck (I mean not just moving…[Read more]

Hello InMoov builders!
Here is a view of the knee actuation. This is done via MyRobotLab with the DIY Servo service.
More to come with the Ankle and Thigh actuation.
Awesome,,, It’s great to see your R&D work on his mechanical operation for this section–,,,
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 started the tutorial for the legs assembly:
Legs Non Motorized
I still need to finish it but I already published it because I see some of you already have started to print them.
Have fun building!!
Thank you Gael for your work. I’m waiting for the end of your tutorial to start printing.
our Inmoov are going to be beautiful.
Get your printers warmed UP!! The legs I had created a long time ago for InMoov are ready to download.
These are the version for standing, not motorized. Beware that some parts exceed the 12x12x12 standard. The reason is that I was not going to upload these parts but time to create the motorised legs is taking much longer because I barely have…[Read more]
