      • very beautiful. it happens almost right on the ceiling.

      • @mindless Actually there are fitment issues if you try to move the legs. Portions of the upper thigh hits the waist. Dremel fixed that all. No other big surprises. I didn’t use the internal reinfordcements or threades rode.
        It is obvious they are pretty much for display and they do not have the degrees of freedom needed to function. Still they are cool.

    • Looks awesome Perry !
      It’s a nice option to use the default servo’s 🙂

      And are you happy with the mechanical results ?
      For you it’s better to see and feel the results instead of the default setup 🙂

      • Thanks Marten. I like it a lot. There is still a bit of tuning to do but the geometries are good and the wrist rotation is solid. I may still put an inline tension spring in place but not sure. Time will tell if it is needed.

    • Great Perry, I see that there is many inventors around!

    All runs more freely and looks OK for me, here the test video with a complete Arm/Hand/Fingers:

    • That is awesome. No tensioning spring is the best feature! I guess you could add a tension spring like you had in your single finger tutorial.
      I think this is pretty innovative which begs the question what does the rest of your bot look like?

      • Hi Perry,
        Yes for sure I will include the springs which I’m using with my Finger_Starter kit.
        This makes programming a closed position more easy and they are to safe the servo mechanical way 🙂

        It looks good so far 😉

        • Once again nice work. It would be great to have a printable shaft for the wrist as opposed to a dog bone. Just another part I would have to wait for when I want to try something late at night. I thought you had a different servo offset in your previous vid and didn’t need the universal joint functionality

          • Thanks Perry,

            A printable shaft would be cool, I only think it’s not strong enough !

        The Wrist servo is blocking the complete way for all fishing-lines.

        So this saves a lot of friction 🙂

        (printer is almost done with the last peace 🙂 )

    • Hello Marten. I came to that exact same conclusion last night while assembling my tendons. They have been very finicky and I am not confident the spring system will hold up.

      It doesn’t look like Blender. It’s interesting to know because other builders might be interested to see how you re-worked your parts with only the STL at start.

      • Hello Gael,
        Working with STL files can be a real hassle as they are among the hardest to modify after the fact. As you can see in the pics below they import with thousands of facets so there are not really planar surfaces to work with.

    • They may save weight but they may not be strong enough for the inMoov hand… The hand is not the same as the finger starter. There is a lot more friction on the push/pull finger mechanisms. The servos need to work much harder than the simple finger kit… However, let us know if they work because less weigh is always welcome…

        I’m almost sure these smaller servo’s are strong enough for the Hand.
        (don’t forget the special pulley which I’m using!)

        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.

    • juerg replied 7 years ago

      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 !

        • juerg replied 7 years ago

          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?

  • Marten de Groot posted an update 7 years ago

    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.

            Which servo’s are you using in combination together, which gives you this “Jitter” problem ?
            Do you have a oscilloscope ?

    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]

      • Hi Gaël,

        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]

      • @Juerg, I’m guessing Amby sees it for the torso and stomach displacements.
        The two armonics drive must be for the shoulders. Though when you know how much an armonic drive cost, you back off a little. 🙂
        @Amby, yes, it is on that U-joint principle that I had designed the stomach rotations.

  • Here some pictures from the new ServoBed:
    I’ve replaced two servo’s more to centre, to get some more hight.
    I’m almost finished with the last RotaWrist parts.
    When these are ready, I need to check the RobCableFront part.
    I need to (re)move some holes in this part.

  • Last night and today I’ve printed all the RobParts.
    Now I’m printing a new ServoBed and tomorrow I will start with all RotaWrist parts.
    When that’s ready, the complete ForArm and Hand are ready for use 🙂

  • Servo Pulley can now be downloaded: http://www.thingiverse.com/thing:1052776
    I will upload more sizes later these day\’s.

  • So, during some spare time this day’s, I’ve printed a complete Right hand.
    All in PLA and everything fits well 🙂
    My next step is to start with the Right underarm parts, so I can install all servo’s and connect these to all the Fingers.

    Here some pictures from the complete Right hand:

    • Woouuiii !
      Nice prints! Well now the forarm and you just about ready to have a Right hand!

      • Haha, I can’t wait…
        I’m printing the last day’s at Day and Night… 🙂
        I hope the forearm is ready in about two day’s.

        Next day’s I will check all the lengths which each finger needs to lift them completely with the new servo pulley.
        So I can start re-designing the pulley for each finger.

  • For the complete Right hand, the Thump is ready:

  • Here a video again, with the new servo pulley which is specially designed for a Finger movement.
    It’s designed for servo’s which can turn a full 180 degrees.
    This Pulley gives a better torque and there’s less change to move to much to destroy the servo or finger.
    There are two option about the spring (in this video I’m using a elastic cord…[Read more]

    • Nice!
      So the white is the elastic cord and it runs all the way to the end of the finger, if I juge the white spot at finger tip.
      What kind of elastic cord? Don’t you think it will stretch more and more over time?
      I also can see the asymetric effect on the black braided line.

      • Hi Gael and thanks for your comment and time 🙂

        The elastic cord is a basic peace which you normally will use for clothes.
        It’s now just to do the job of the spring.
        I’ve ordered some springs and have to wait they will be here.

        I hope the asymmetric effect is in a positive way 🙂

      Hi Marten
      I think before changing the pullies we should agree what the mechanical requirements are for the fingers.
      In my arms I use mg996R and they can turn about 110 deg to the left and to the right (total 220). So when Gael says he can move all fingers with the exception of the middle one with an unmodified HK15298 servo which allows only 45…[Read more]

      • Hi Juerg,

        Thanks for your input about this.

        The good thing to use a 180 degrees pully, is that there is less change to break any mechanical parts.
        A other good thing is, there is a higher resolution to place/hold the finger at his position.
        Have you seen my Finger Starter video ?

        • juerg replied 8 years ago

          Agree that individual pulley’s for your combination of servo and finger would be safest for builders. Just go 0 to 180 without having to worry about limits.
          I am rather the software guy and think – once the mechanical part looks good – I can control movements with the mapping function of MRL.

          I always like to see videos, they tell so much more than words!
          That carbon filament is great looking!
          I did make a Arduino script when I was testing the carbone foam sensors on the finger starter. I’m wondering if I still can find it in all my data. It could maybe help you or others, as I recall it was a bit of a different approach.

          • Found the script back in my data base:

            • Hi Gaël,

              Thanks for sharing your code to.

              The best way to use this sort sensor, is to include a servo slow (step-based movement) which I have included in my code.
              The code what I’ve shared isn’t the code what we need right now.

    • Hey nice Marten!!
      I like that Carbon PLA. I remember the parts you showed me in Eindhoven, the quality was very good!
      Pulley rotates 90 degrees because the HK15298B digital servo recommended for the hand rotates only 90 degrees.
      That being said, you can use any servo you like with Finger Starter and of course model your own pulleys. 🙂

      • Hey Gael,

        The CarbonFil is more PET based !
        And yes, it’s nice material to use but it needs some attentions for the first layer.
        (OK I’m still playing with some settings like Nozzle Temp and PrintSpeed)

      Hey looks great. Many, many more parts to print however …

      • I don’t now yet with the fingers.
        The CarbonFil is great stuff and feels strong.
        I’ve used this to make some prototype parts for my Camera Gimbal.
        And it didn’t break 🙂
        For now I’m still waiting for advice about which glue I can use for this CarbonFil.

        I will come back to this question if I now more 😉

        • juerg replied 8 years ago

          thanks for your comment. What is your print bed made of and what temp / preparations do you need to make the pieces stick to it?

      • I got the same trouble. Happily with abs it can be repaired quickly with acetone.
        Some times after I found this tip, just heat to smooth the holes. It looks like Mats Önnerby tips with airgun to mount pla parts but with a solder iron.
        Have a look on this video :

        Hope it can help.

          For CarbonFil I’m using a temp from 255 C and the heated bed is set to 60 C.

          • juerg replied 8 years ago

            I think I will sit down and create a video about my finger assembling techniques including the strings. Watch out for it.

    • Great prints Marten!
      In the video posted by Sebastien, the idea is great! Specially if you drilled the holes a bit too wide.
      But be sure that finger stays loose, in the video they are stiff, rigid, and that is not okay for the movement. The finger should move freely at each joint.

      • Haha, yes the video is good for all the joint parts.

        I was more focused how to glue all fingerparts together like part-1 with part-2 etc….
        CarbonFil is PET based and PET is difficult to glue normally.
        I hope the 30% of carbon-mix will make it easier to glue this together.
