• Just want to share a video that was created by Lakhwinder Singh when Markus, Robyn and I visited the Indian Institute of Technology in Rorkee earlier this year.

  • I am programming my InMoov using EZ robot software. I have taken his forearms off as I am updating his servos for his hands, so only part of him works at the moment. His head, neck and torso is working in this video. I have added an adapted “Bob Houston” neck on him by Gestalt73. Fitted a speaker in his mouth, but need to work on the…[Read more]

    • Lorn, that’s brilliant. How long have you been working on your Inmoov? I’m using EZ to co troll mine but I’m not as far ahead as you. Where are you in the UK?

    • Looks great, but you had me worried for a moment when I compared to mine! Is there a reason you’ve mounted the eye mechanism upside down vs. Gael design? Does it give you some benefit? I don’t have a completed skull yet, to see how the clearances and space work out with your orientation. :)

      • Hi Wayne – very good point about it being upside down! I am not sure if it will fit in the head that way around but at least I could hold it in the vice whilst taking the video. Been waiting on the camera parts to arrive before I finish the head – camera finally arrived yesterday.

    • 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.

    • 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!

      Saved me $$ on springs!

    Hi mats
    Currently on vacation in Japan (they have some nice robots here too but InMoov is not popular here).

    • 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

    • 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.

    • 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?

        • 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.

            • 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.

      I tried so many things and materials for the perfect printing bed before starting InMoov project. Blue tape, UhU glue on glass, Buildtak, Ninja Board, ABS slurry on acrylic, bakelite and so on. I use…[Read more]

      • I use a Velleman Vertex K8400 printer with an unheated glass bed with BuildTak. PLA sticks well to it. The BuildTak has to be replaced about once per month. I have never tested ABS. The printer has three fans to cool down the PLA. I have to use a lot of force to break any part. It they break, you may have to little infill or to thin walls. I use a…[Read more]

        • Hi Mats
          never seen BuildTak before but the web page promises exactly what I got with my material. I haven’t touched my printbed for 3 month’s now with printing times in average probably 3 hours/day.

      • It looks to be kept secret what material it is. It is also rather expensive but after having encountered so many problems I gave it a try (beside other materials) – and at least for me and my PLA-HT it works like a charm.
        When I compare ABS prints with the PLA-HT the second is much more robust (like I can not brake the large lower arm parts…[Read more]

    • 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.

    Replacement Servo for omoplate

    After burning quite a few HS805BB I wanted to try another smaller servo which had interesting specs, the tgy-mg959 v2.
    I have added the redesigned holster which maintains the geometry to thingiverse (look vor InMoov omoplate).
    It should also work for rotate and shoulder and sure would look sharp on the robot.…[Read more]

    • Awesome good test and results! Thanks for sharing Juerg.
      Definitely something usefull for to make the servos smaller. Speed seems to be the same as the HS805BB, what are the torque specs?

      • Hi Gael
        Thanks for your comment.
        I bought it for the hobbyking statement 30kg/6v and 0.15s/6v for 60 deg. The servo I got is named v2, but you can also find other statements where only 15 kg are given. Do not know but performance looks to be acceptable and I am quite sure it could be good for other HS805 replacements. It is rather easy to change…[Read more]

  • I had several ideas when I started to print the head. The large servo was more expensive than a small, so I tried to replace it with a standard size sero. I also wanted to mount a better camera in the head than a USB camera. My modified head contains a Raspberry PI 2 with a Raspberry Pi Camera module mounted in one of the eyes. It also contains…[Read more]

    • wooouu, setting the brain in the skull.
      What sort of camera did you set in?
      I tested my full InMoov with the Raspi2 and was a bit disapointed with latency. The Odroid U3 was also having latency…
      Let us know your Rasp2 acts when you will be using speech recognition along with OpenCV tracking, so we can share comparison.

      • I use a Raspberry PI Camera module connected directly to the Raspberry CSI port. I has really good quality for still pictures and video stream is OK. I tried to use it with MRL and the OpenCV service, but I got some error messages. I will sort it out with the developers of MRL. Thay are all very nice, skilled and helpful people.

        • Others have tested the Raspi Camera module into MRL with success. Your errors might be related to which version of MRL you are using.
          When I tested the camera with the Raspi2, I was using version 1.1.107 and it was working fine, though with latency.

  • This is a part of the Bicep. I use PLA, and it's not as soft as ABS. So when I tried to mount them together, it was impossible, because it wouldn't flex. But PLA gets soft at relativley low temperatures, so I used a heatgun at a low setting to heat the connections. After heating the plastics for a short while, it was easy to mount them together.…[Read more]

  • Hand and forarm printed in black PLA. I use recessed M3 screws to hold it together. I drill a 3mm hole in the part to be mounted. In the part that it should be mounted to, I first drill a 2.3 mm hole and then I use a 3mm taps to make a thread. It's not easy to make the thread straigth by hand, so I mount it in a drill.The 8mm screws are made from…[Read more]
