    Hi Steve,
    You need to mound the Rob Rings under the servo-pulley !

    Hi Juerg,

    The servo is mounted with two screws to the blue part.
    the blue part has the option to slide in the light grey part.
    Here you will see both parts separated:

    Hi Ashley,

    Welcome to the InMoovers :)

    MRL is (in my eye’s) much stronger/faster then Arduino IDE/Boards itself.
    It’s running at a faster system then a single Aduino board, so there are much more options possible.
    And the InMoov is a default Robot in MRL which is cool and more easy for beginners.
    There are some Python script made by other…[Read more]

    First servo slider test run:

    tomorrow I hope to add the (to big) FSR sensor and see what it will do :)
    (I’m still waiting for the smaller FSR’s)

    • hey Marten
      nice to see you are working on this. can’t really see from the picture how the servo will be able to move. is it mounted on the blue part? but then it would need 2 screw holes on each side in the blue part?
      and just realize that I do not know what servo make/type you are using.

    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.

    CollorFabb PLA is good material anyway.

    @perry-scartozzi
    I can\’t wait to see your idea :)
    Which program(s) are you using, during re-editing Gaël\’s STL files ?

  • Instead of a DogBone shaft, I’ve designed a new small Wrist_Gear and servo-adapter and will use a 6mm hexagonal shaft.
    I hope the 6mm hexagonal shaft is strong enough :)
    Tomorrow I will print all parts and if it works fine, I will include these parts to the Wrist upgrade set @ Thingiverse.

    I can\’t see that these smaller servo\’s can hold it for a longer period :-)
    But so far it looks good and including the springs I think it\’s safe enough to use them!

  • Marten de Groot posted a new activity comment 5 months, 2 weeks ago

    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?

I thought you had a different servo offset in your previous vid and didn’t need the universal joint functionality

    (I’m still waiting for the new servo’s, so a second video will come soon !)

    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?

  • Finally the Arduino fits well in the updated FingerStarter_Kit.

    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

    • 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.

    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?

The servo works just fine on a tester etc. I have seen in the tutorial, the…[Read more]

    • 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]

    Looks good Anthony, I think only you need to start the fans from a higher layer !

    • From a math point of view, an excentric pulley will work very different. With two tracks, it’s just linear movements. The excentric can only work between very limited angles. With two tracks, you can rotate any angle. The ratio will still be the same.

          The code what I’ve shared isn’t the code what we need right now.
          It was just to test the reaction from the sensor as I showed you in Eindhoven.

          If we use a step-based movement, the…[Read more]

    Here the Arduino code, which has a servo slow function included:

    #include

    Servo myservo; // create servo object to control a servo

    int potpin = 0; // analog pin used to connect the potentiometer
    int val; // variable to read the value from the analog pin
    int Pos;

    void setup()
    {
    myservo.attach(9); // attaches the servo on pin 9…[Read more]

      • Hi Marten,
        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:

          #include

          const int servoPin = 3;
          const int sensorPin = A0;
          int sensorReading;

          int pos = 0; // variable to store the servo position

          Servo myservo;

          void setup(){
          Serial.begin(57600);
          myservo.write(0); // Open finger.
          pos = 0;

    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.

  • Marten de Groot posted a new activity comment 1 year, 6 months ago

    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)

    About the servo:
    The thing what I hope to test, is that we can use smaller servo’s so we getting less weights in the Arms !

    Haha, It\’s good that you say that the nails where painted by your daughter :-)

    For a first print it looks very well printed.
    Have fun with it.

    (I see you have placed a link in your message, is the link bug fixt ?)

    • Hello Marten,
      haha i’m going to open the first french manucure for robots :-), most seriously i think to use this to easily detect the finger position using color detection in the pictures

    Hi Grant,

    Welcome to the InMoovers :-)

    I think it\’s good to start with the Finger Starter kit so you can start playing around with MyRobotLab during all other printer actions.

    Have fun… :-)

  • So, just finished the Finger Support plate for the servo and the Arduino board.
    I hope to have some spare time tomorrow to buy some glue for the finger parts.

    For the servo I will draw a smaller pulley so the servo can give more torque with less power.
    (original it use 90 degrees to move the finger up and down, I like to give it a try to use…[Read more]

    • 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. :)

    Hi Juerg and Sebastien,

    I’m still using the standard clean glass plate from the UM2.
    After each print, I’m cleaning the plate directly when it’s still hot.

    For CarbonFil I’m using a temp from 255 C and the heated bed is set to 60 C.
    I’m still playing with some settings.
    Most important thing is that the plate needs to be levelled well and…[Read more]

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

  • Marten de Groot posted a new activity comment 1 year, 6 months ago

    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 ;-)

    • Hi
      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?

  • Just finished the last finger pieces for the Finger Starter Kit.
    All are printed with CarbonFil with a 0.2mm layer hight.
    (I now, it’s better to use 0.1mm :-) )

    • Hey looks great. Many, many more parts to print however …
      I give a filing to the finger parts where they move against each other because the printing in layers creates imperfect vertical surfaces.
      I do not want your pieces get broken but does it feel like the you might brake the parts when assembling them? I broke several with PLA and ABS when…[Read more]

      • 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.

    • 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.

    Hi Gael,

    Thanks for your offer about the spare hand ;-)
    It’s no problem to print it myself, it’s a good test for my new UM2 configuration.

    I think there is a easy way to place a magnet in the top from the Vingers.
    This peace is printed in two parts, so I can drill a hole from 2mm in on of the parts.

  • Hello InMoovers,

    Last week I received my six servo’s for one InMoov Hand :-)
    I hope soon to start printing this.

    Before I start with this, I like to upgrade my UltiMaker-2 with a new 3DSolex Olsson Block and a BuildTak 3D Print Surface.
    I also ordered some extra Nozzles for this Olson Block.
    – One RVS 0.4mm for printing with CarbonFil.

    • Woouiii you are going to make wonders with that printer!
      You should have told me when we were in Eindhoven that you wanted to build the hand to make some tests with the hall sensor, I could have brought you one that I keep for my robot in case it breaks.
      Yeah, print first the finger starter it will be easier. Let me know for the finger tip design…[Read more]
