    I have started to replace broken HS805BB with bluebird BMS L530MG (hobbyking). I have one for my bicep and another one for the neck. The bicep initially worked fine until the horn adapter started to slip (the lower arm is a heavy bugger). I recommend therefore metal servo horns with the bluebird servo. You need to order them separately.…[Read more]

    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]

      • Update: Actually had a problem with left shoulder rotation servo (continuing small repositiong with growl) and after a while it stopped to move (fuse and servo rather hot) so the fuse did it’s job.

      • 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.

    Replacing a broken HS805 with a Blue Bird BMS-L530MG in the bicep. Its available at 20 Eu from hobbyking. Almost same specs but a bit shorter. It’s easy to remove the pot as it has a floating controller board. Downside is it has a smaller servo horn and so the rigid plate connector included with the HS805 does not fit.

        Thanks for pointing this out and sorry Markus for not mentioning you instead. I mixed up your names and it’s Markus who holds the record in disassembling InMoov for transportation in a suitecase!

    • Hi Juerg, the route that Markus took with these connectors was very impressive.

      This looks very promising for handling beverages and other delicate tasks.
      I will Google+ your video and add the parts to the derivative collection because it’s very interesting progress.

      • I just wanted to thank you all for the replies I received for my modified hand from different sources. I hope to see soon a copy of my hand on other InMoov’s!

  • I’m almost finished with the mechanical build and the testing of each servo individally. Next step is to purchase / build and install all the electronics and batteries. The back is still a bit empty.

        • I also realised some time ago that using the latest version of MRL which uses OpenCV 3.0 that I would get a low fps result. I was recently mentionning that to Grog and he said he would digg into it.
          So, using the Lenovo tablet touchpad with the version 1.0.107 gets me with a a fps of approximately 30.
          Using the version 1.0.954, gets me to a 7/10 fps.

      Very cool movements .

    • Ah cool!
      Finaly you can post videos again!
      I see you replaced one hand with the Flexi hand?

    • Nice video, Bob!
      I see the wrist also has a movement linkage. You might want to share your work with Juerg, as he is also working on something similar.

      • Yes, I hacked a flexihand and put the servos for the fingers in the palm of the hand and added a servo for the additional wrist movement. I have also just finished adding flexible joints to the original InMoov hand and it works pretty good and can hold objects fairly well. I posted a couple of videos on Youtube about the flexihand.

      • RIght, you take a new route with servos inside the hand – very nice!
        My bending wrist uses another servo in the forearm and a few modifications on the existing wrist and hand parts – and it integrates a position sensor to allow the hand to stay horizontal. I am waiting for some cabling stuff as I want to have the forearm pluggable to the elbow.…[Read more]

    • Looks great! The flexihand seems better controlled – is that due to a design improvement in the parts or just better tuning during installation?

    • 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!
      Thanks a lot for it and for sharing it over thingverse!

    @monnerby
    Hi mats
    Currently on vacation in Japan (they have some nice robots here too but InMoov is not popular here).
    I can’t draw you a picture with my mobile but look at this – the servo has to travel 17 plus 27 mm for complete opening and closing. Depending on the servo you have installed (my mg995 can do about 210 degrees) this will be…[Read more]

    • Hi Juerg. I appreciate that you want to help. But from your answer, it is obvious that you don’t understand the basic problem. It has nothing to do with centering the servo. The servo needs to pull 27mm on one side to close the finger, while releasing 17mm on the opposite side. That is a difference of 10mm. Not a sum of 27 and 17. To open it…[Read more]

      • 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?
