    Just started building InMoov. I’ve printed the right forearm and hand. I’m now playing (not really, it’s not so easy) with tendons, then I’ll use LeapMotion (fully configured).
    Next, will print right arm and shoulder, then the left parts.

    For those living in France, Decathlon sold Fishing line (1mm / 280 Lbs) at a not too expensive price (18 euros) :
    – Marque : Fatkat
    – Type : Bas de ligne
    – Tresse Kevlar – Aramide
    – Nom : Power Leader Kevlar

    3D Printer used : 3D Freesculpt (from Pearl Diffusion). A not so expensive printer (around 800 euros), with an acceptable quality 🙂

    Servo purchased from Hobbyking (HK15298), but the transporter they use is not really reliable where I live, and Roboshop for the others servos.

    Thanks to Gael for his project 🙂

    • Pictures!!!! 😀 😀

    • Yeah we want pics! That’s what I eat for breakfast.
      So Decathlon has InMoov tendons, that’s good news.

      • I’ll post pictures when the arm is ready. At the moment, I’m looking for the best way to fix the tendons. I am trying to print the Funlab actuators to test.

        I must say that the setting of the tendons is the most difficult part of the mounting arm.

        The ideal should be a (in french) “Tendeur 2 oeils” for each tendon, but I did not find one sufficiently small: (

        Don’t know how to post picture, so here is a url : http://www.ancrest.com/upload/img/tendeurs-tenvit.jpg

        • The spring called “ressort tension” is more interesting I think, as I already suggested in various posts to use a spring on the retract tendon to keep both tendons always with a correct tensionning.Images intégrées 1

          • I try to use a spring on the retract tendon retraction in a few days because the tension on the servo is too strong and it suffers from this tension.

            What kind of spring do you use or recommend ?

            • Damn, I tried to post a picture in my previous comment to show you how to set the spring to avoid the tension you are describing on the servo, but it didn’t show. I will send it to you by mail.

    • Hello,

      I need some help 🙂

      I’ve (finally !) finished my arm, and I’m trying to move it with Leapmotion. The wrist move correctly, but none of the fingers moves 🙁

      What I’m missing ?
