    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!

    • Thats a good idea! Can you share details on how to install them?

      • Sorry, yes, just route the connection from either plus or minus pole from the power supply to the servo through the fuse. The fuse is supposed to heat up with current flowing through it and increases resistance thereby lowering the voltage for the servo and make it stall. The fuse regenerates when cooling off.
        The fuse works in a slow mode so…[Read more]

      • thanks, great picture but I do not use nervo boards.
        the pin right next to e.g. 12 is the signal line?
        the dark green edged pins are the + power ones?
        the 100uF ground side is on the signal?
        and 104 is a 100 nF cap?

        • the 100uF ( the big chimical, it’s bad we need ceramic ) is pluged to +6v ground power line .
          The 100nF ( The small 104 ceramic ) is pluged to each signal pin. ( +signal , ground )
          The signal and the power shared the same ground.

          • Great! I remember a post on the InMoov forum mentionning something similar, It sure would be great to add that option on the next Nervo boards release.

              I see a lot of warping at the bottom side, this happens when the PLA is cooling down to fast.
              The best way is to start slowly with the fan speed around layer 30 (3mm if you are using 0.1mm layer)

            • Also check that the print bed is close to the nozzle. If the distance is to far, the first layer will not stick well to the bed. The first layer should create a solid piece of plastic without gaps.

    • Hi Marten. I just cut of a few mm’s of the hand cover support. It’s only there to support the structure during print. I don’t want to replace the dual track pulleys since they work very well. Have a look here for a demo https://www.youtube.com/watch?v=b5S-8hjsMr8

      • Hi Mats,

        I’ve seen the video and the results are perfect !
        The option was more meant to update the Pulley’s for other InMoov builders, how like to use your Pulley’s, so they haven’t to cut anything 😉

        • 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.

    • Maybe reducing the filet height for the tendon, this way the pulley would be less high and wouldn’t cause a problem with the covers of the for arm.

    • Awesome solution for tensors Mats!

      • Hi Mats
        I think I got your point. When doing my first pulleys I had problems that they interfered with the cover, adding a second track would require lower built servos or a modified servo-bed? And the string-guiders will need to be adjusted?

  • A litte update to expain the reason that I redesigned the servo pulleys. I use the fingerstarter to explain. In the first picture the hand is open and both lines are stretched. On the second picture the hand is closed, but the lines are not stretched any more. To close the finger the servo pulls about 27mm and releases 27mm on the other end. But…[Read more]

    • Pictures were uploaded in a different order than I expected. So the last picture shows the open finger with lines stretched and the two other when it’s closed and the lines are not stretched anymore.

      • hi mats
        Maybe I see things the wrong way but I do not understand why you have to modify the pully. Set your servo to the middle position than add the pully with a 10 mm offset towards the closing side. In MRL define a mapping that covers the 44 mm range for the full movement with your servo?

  • Video of testing the new servo pulleys for the hand. https://www.youtube.com/watch?v=gwx3JIakDV0

  • I have made new servo pulleys for the hand. They have two tracks with different diameters, since you need to pull a longer distance to close the hand than to open it.http://www.thingiverse.com/thing:1074604

    • This looks interesting – How would you describe the improvment to the hand’s movement?

      • To close one finger you need to pull 27mm but to open it again only 17mm, The 10mm in difference will result in that the lines easily fall out of the tracks, The servos will also have a deadband of 10mm before they start to pull, With this construction the lines will be stretched all the time, so the fingers will keep their position better.

    • The reason I am asking is if you think the springs that were introduced to keep the strings tight would still be needed ?

      • Good question. I don’t think that springs are necessary, but if you turn the wrist, the lines will be tightened. So you have to compensate for that by relaxing the tension on the lines a little,

        • Hi Mats
          Can’t really see why you want to modify the pully. Put your servo to middle position and add the pully with an offset to the closing position that will account for the different distances for opening and closing. The use the mapping feature of mrl to adjust the overall distance for your servo in use?

  • First test of the servos. The neck works fine. Jaws needs to be changed to increase the speed of movement. Eye servos tested but not connected to the eyes.

    • That looks like a very good design I really like the eye movement

        For the springs – I think it’s good to keep the strings under tension – great pictures and nice cabeling! But e.g. a bit of a fragile object might still be broken because the servo won’t stop?

        • 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…[Read more]

          • @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.

            • Springs will the best/easiest way to solve the problem.

              I will use this Pully, including a spring to let the finger go down again.

      • I got totally excited myself when finally I could mount them on my InMoov.
        Yes I will release them. A few little things to modify, specially where the clavi potentiometer rotates, and also the battery holder needs to go a little lower to let access to the power cable of the Tablet.

    • That is a really nice back. Looks good and will protect all the electronics and hide some of the servos.

  • The eye mechanism can be found here: http://www.thingiverse.com/thing:1035688
