Here some better pictures the new servo Finger pully together:

  Interesting design! I like the idea to set the servo horn within the pulley. They might be a bit too thick to fit under arm covers though… Let us know.
  - Marten de Groot replied il y a 10 ans et 4 mois
    
    Thanks Gael,
    
    And good to now about the limited thickness.
    I will check this when all underarm parts are done.
    There is a easy way to save some hight if needed, I can include some holes for the two screws.

    Hi Gael,
    
    Just checked the hight and it fits fine.

I’ve made a other servo pully.
I hope to get soon the springs because they are needed in this design.
Here two pictures from a mounted pully at a servo and a picture with some views from the drawing:

  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…En afficher davantage

    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 ?

      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.

      The basic problem is that the you need to pull a longer distance in one direction that the other. For example the major finger needs to be pulled 27mm to close but only 17mm to open. So the servo pulleys needs to be redesigned to have two different lanes, with different diameters. I have started to experiment, but the pulleys I try now are to…En afficher davantage

      @juerg, the servos won’t break parts, at least it never did on any of the hands I have assembled. In MyRobotLab you set the Min and Max for each servo, this avoids the servos to force further than necessary.

      Thanks for posting the spring design. I think springs has to be part of the solution, since turning the wrist will pull on both sides of the servos. A different design of the pulleys may decrease the length that the springs need to flex.

  Hey teaching about something you need to learn first, why not! InMoov is the teacher and we are his students trying to learn how to make it work.

      Hi Stefan. Depending on your printer and the material you use, you may have to scale the parts. I suggest that you start printing either the Fingertester part of the Fingerstarter or the Servobed from the Hand. That way you can test how well the servos fit. If they don’t fit, the use the slicer to scale the object so that they fit. I print with…En afficher davantage
      
      Stefan Ekstam replied il y a 10 ans et 5 mois
      
      Thanks for the tip! I will print the Servobed to check this as soon as possible. The servos have not arrived yet, and the final parts of the right hand and arm will be printed this weekend, so I’ll just have to hope that the parts I have printed so far will not be completely unusable… I’m using ABS by the way, since that was Gael’s recommendation.

  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. 🙂

    I got the same trouble. Happily with abs it can be repaired quickly with acetone.

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

- Gael Langevin replied il y a 10 ans et 5 mois
  
  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.
  - Marten de Groot replied il y a 10 ans et 5 mois
    
    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.

  Buildtak didn’t work with ABS for me, I managed to nearly destroy the surface after the third print. ABS temperature is too high for the Buildtak and causes to scare the surface rapidly. I didn’t try with PLA. But I have seen very good results at various 3D print shows.
