Assembly of the head.

This is fairly simple, so I won’t extend myself on this part.

Be sure to assemble the mechanisms that are inside the head before putting the outside shell together.

    Dear community,
    just started my InMoov Project and decided to go for the head & neck first. Do you have any advise where to use the 2 different types of bolts (threaded bolt & wood screws) …. E.g Use threaded bolts to fix all 3D printed parts?

    Any Feedback is very mucg appreciated.

    Hello Gael,
    I was about to finish the head and everything works fine, except the recommended servo HK12598 for the yaw.
    First it did not rotate at all. After changing the MRL min/max values to something like 40/140, the servo at least rotates, but only approx 90 degrees rather than 180.
    Do you have any idea how to make the HK12598 work, or can you recommend a different servo?

    Regards,
    Sven

      Hello,
      The 90 degree rotation of the HK15298 is largely enough to operate the jaw, no need to look for another one.
      Each servo needs to be calibrated with their min and max values in the skeleton config files. This is very necessary otherwise you will eventually burn some servo.
      To calibrate a servo you can use the tool which is located in the directory C:mrl/myrobotlab.1.0.2693/tools. This will launch a Arduino service and a Servo service. You can use it to determine the minimal and maximal course of your servo in order to set the correct values in the skeleton config files.

      Indeed, I do not put the required specs because it varies too much depending on your software and printer.
      In general I print most parts with a perimeter of 2.5/3mm, infill 30% with a resolution of 0.3mm for regular parts.
      For gears and parts that cary heavy load, like the shoulders for example, use a perimeter of 3.5/4mm, infill 30% with a resolution of 0.3mm. If your perimeter is strong, no need to add excessive infill which adds unnecessary weight.

        Awesome! Thank you very much Sir! I just want to get this first model done as correct as possible. I am only doing a shell of the Inmoov so I can present it at the school board meeting. I want to introduce the Inmoov to our robotics club at the Middle and High schools here in Georgia. Our guys still build battle bots out of toasters and such and I want to give them something more.
        I’m no teacher just an active parent.
