    Hello all,

    At the end of this month (June 2022), I will proudly participate in the monthly Engineers Teams meeting at my job to explain and show the inMoov project and how I start this adventure.

    The aim is to teach them that we can do great things by combining Open source projects, Mechatronic solutions, Arduino platforms and Team work.

    Hello, I need help, I have a problem, I have soldered all the pins of the nervoboard, but when I connect the nervo to the arduino mega to my computer, the script to put all the servos of the hand except the one of the wrist does nothing. The impression that the order is not transmitted, do I need a power supply other than USB? Does anyone see…[Read more]

    • Hi.
      Yes, you need an additional power supply for the servos. I suppose the current would fry your arduino.
      I reused a 5V power adapter. I soldered a XT60 male adapter to the nervo board and a XT60 female adapter to the cable of the power.adapter: This way I am able to take away the current if my servos develop a life of their own.

    • USB power for the most part is limited to 2A under the USB2.0 standard.
      The average servo will draw between 2 and 3 Amps each.
      You will defiantly need a bigger source of power.
      I suggest a 6V power supply.
      If your planning on using it to power the whole of the Inmoov robot, then a 50 Amp power supply is recommended.
      There are other ways of…[Read more]

    Hello everyone, I have already finished my head 🤔 well, not what is said to finish because I have to put the speaker and the nervoboard 🙂

  • After installing Fred\’s left Bicep, I asked him to record a video for me.
    This went well until he went to point to the virtual white board on his right side.
    Now he not talking to me 🙁
    So now I\’m working on his right arm 🙂

    I have small problems with the mechanism of the jaw 🙁

    I followed the instructions: inmoov.fr/neck-and-jaw/

    I set the servo to 0 and mount the “JawHinge” at 90 ° (for a distance of 1 cm).
    I tested my servo (movement from 0 to 20 °). At 0 °, my robot has his mouth open. At 20 °, he opened it even more …

  • Fred\’s been at me for a while now on getting him some Arms.
    Here is the start of the left Bicep.

  • The final part of Fred\’s Left Shoulder.
    Here we set the feedback pots position and test it all out with MRL.

  • Fred\’s Left Shoulder Part 4.
    It\’s all coming together 🙂

  • I recently got a new toy.
    I don\’t normally post unboxings in here, but this is so handy when setting up your servos.

    This servo tester is great for positioning servos and testing the range before connecting the servos to the servo drivers and fire up MRL.
    I also opened this one up to see what was inside it.

  • In this video we will build and add the bicep rotator to Fred\’s Left Shoulder.

  • Part 2 of Fred\’s Shoulder.
    More worm drive fun and games 🙂

  • Since Fred was insisting, I started on his Left Shoulder.
    This is the start of the new version of the shoulder with the ball bearings.

  • Just for a laugh, I turned on the webcam to record Fred 🙂

  • When your building a robot, sometimes, you need to sense a signal or a voltage that is well over the rating of your input.
    This is not a real problem, because you can use a voltage divider to drop the voltage down a proportional amount.

    I did this with Fred’s battery monitoring inputs, where the Battery voltages can…[Read more]

    The other major difference, is in the way I control the servos, using the PCA9685 I2C 16 channel…[Read more]

  • Fred\’s Right Shoulder Part 4.

    I released this a few weeks ago and for got to post it here.
    The shoulders in Fred are standard, latest version from this site.
    The new ball bearing setup are much smoother.

  • Continuing with Fred\’s Right shoulder, during this I find an issue with the pot and have to replace the pot.

  • In this video, I print out and assemble more components for Fred\’s shoulder.
    I also mount the shoulder assembly onto Fred\’s upper torso and set the feed back pot position.

  • Today, I start on Fred\’s Right Shoulder.
    This updated version of the Inmoov shoulder has bearings in it 🙂

  • Continuing with the Fred\’s Brain series, this time I look a speech services.
    Both TTS and STT

  • So last week I unboxed a new Raspberry Pi 4 with 8G of RAM.
    This week, I setup the OS and install MyRobotLab on it.

  • In this video Part 3 of Fred\’s Brain, we continue looking at MyRobotLab and how we use the services to setup and control Fred.

    • I really enjoy watching your videos Ray. The way you explain things is great. However I have a confession. I have gone over to the “dark side” that is ARC. I am now running EZ-B controllers and find the ARC software much more intuitive and simpler to work with. I have modified the Nervo Board to suit the new setup.
      Keep up the good work. Warren

      • In the world of robotics, there is no dark side, unless you plan to have your robots destroy other robots ect.
        There is only different 🙂

        In any case, keep on building and posting your progress 🙂

        • He won’t be destroying other robots. His main role is to teach my students about Robotics and AI. His secondary role will be to help teach kids sign language. The second part is not proving straightforward but, I enjoy a challenge. 😉

          • I do remember seeing another design of hand created for the Inmoov robot by a builder that allowed side to side motion of some of the fingers.
            It was posted on Thingiverse.
            It does require more servos 🙂

  • I needed to know what the battery voltage was and also had some issues with the MPU6050 running with the Raspiberry Pi 4.
    To I added one to the I2C port on the Arduino Nano.

  • Part two of Fred\’s Brain.
    In this video we look at the Servo Service in MyRobotLab and how we set them up on our robots.
    Fred has quite a number of servos, and once the arms and hands are attached, there will be a lot more 🙂

    • Great video Ray. I wish I was as confident at writing code.


      • Keep in mind, I’ve been playing with this for 6 years now 🙂
        Confidence comes with time.
        If you go back an look at some of the very early stuff from Gael, he wasn’t confident with programming at all, Look at what he’s doing now and you would think he was a full time programmer instead of a best in field sculptor designer. 🙂

    During programming and testing, I noticed the Raspberry Pi running MyRobotLab was throtteling and reporting low power.
    This has started since the program has been using the two UltraSonic sensors attached to the Arduino Nano.

    Lets try and explain it a bit better 🙂

    • Fred is going great and you have really helped a lot understand how to assemble an inmoov. It also shows, one should feel completely comfortable modding it. This child needs to mutate and change over generations to survive.

      • Modding also makes you go further in to the learning of how things work 🙂
        Good news is there are a lot of Inmoov builders that bring knowledge to the group so we can all learn.
        Most of the printed mods in Fred were created by other talented builders.

    This week, I have fixed that and now Fred is standing
    He\’s taller than I thought he would be, either that or I\’m shorter….

  • Continuing the video series on the Static Leg,
    Here are the thighs 🙂

  • Turns out the Inmoov robot is taller than me 🙂

    • Love the red. I’m enjoying your videos on the static leg assembly. I’m interested in the sizes and quantities of any nuts and bolts used.

      • Hello Steve,

        The following quantities are for each leg, so you will need to double them for both legs.
        1 x M8 x 125 mm and 1 x M8 x 95 mm long for each knee.

        • Connecting the knee to the Tibia I have used 3 x M4 x 40 mm long with the head of one flattened to allow it to sit flush against the front wall of the Tibia when facing up.
          Theses could have been 25 mm long, however only had 20 mm and 40 mm long on hand.

      • Hello Steve,

        The last video in this series is scheduled to go live on Friday.
        Do you link it would be helpful if I include this list of parts in the description as well?

        • Yes as it will make it easier to find. The info will probably get lost in this forum as time passes.

          • Good news is, as a result of your request, I also went back to the last video, and added the parts list in the description of the Video.
            If one person asked, then there will be many other who will want to know as well 🙂

  • Now complete, Fred\’s Knees

  • So continuing to build the static leg for Fred, my build of the Inmoov robot.

  • Ok, so i started to print out the feet and ankles.
    So far all looks good.

  • Since the last video generated some interest in my build of the InMoov robot (Fred) I thought I would pull off one of his arms and give you a look inside.

    • Great job Ray. The print look outstanding.

      • And that was done with what was then a very cheap CTC printer back in 2017.
        The printer also had errors in the calibration of the X and Y axis, so all joints had to be filed to make them fit.

        So even with a crappy print, you can still build a working Inmoov 🙂

  • It\’s been a while since I did anything with the Inmoov project.
    So I decided to print the Inmoov statue again, but this time at 300 mm tall.
    Came out OK.
    But have a look for yourself 🙂

  • Just a splash of red paint, cause everybody knows, red goes faster….. ;=)

  • 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.

      • 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.

          • 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.

  • Fred InMoov first video, shoulder view of Bicep rotate.

    • 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]

    • 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]

    • Nice and smooth. Your print quality looks really good with no banding.

      • 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]

  • Success,
    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.

  • 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

        • 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.

  • 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]

    • Hello Mats,
      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]
