      Nice work,,,, are the -Mecanum Wheels- on the other side any good..?- I v seen them on other projects and was wondering are they an improvement over the wheel or do they just look really cool,,,,,

    Hello InMoovers,

    I like to include the FSR (Force Sensitive Sensor) to all my finger servo’s.
    https://learn.adafruit.com/force-sensitive-resistor-fsr
    For the starter_kit I’ve re-designed some servo adapter things, to make it possible to slide the servo forwards/backwards.
    Next step, is the position-holder for the FSR.

    To get a idea how it looks:…[Read more]

    I made a small upgrade of the shoulder servo. The small potentiometer broke, so I use a larger potentiometer with a 6mm shaft. It’s the olny part that I have changed,but I think the same principle can be used on all potentiometers. The new potentioneter can rotate 270 degrees instead of the original 180 degrees, so the servo mapping has to be…[Read more]

      Hello Mats!
      That for sure is a safe pot!!
      But you didn’t use my latest pot holders, that means your parts can no longer fit PivTit and RotTit of the latest version…
      I guess, it’s because you already had PivTit and RotTit printed from the previous version. I like your little potentiometer board option, it’s handy for to simply disconnect.

        Hi Gael.
        I added two versions of the pot holder to Thingiverse. They fit the latest version of the shoulder. One version is without the cable guide and the other with the cable guide.

    Before I can start with my complete InMoov, I need to upgrade my UM2 filament spool-holder.
    I’ve ordered some COLORFABB_XT spools with 2.2kg filament 🙂
    Not sure if XT filament is the right choice for some mechanical parts.

      yep… Colorfabb is great stuff, iv tried every brand/type out there ,, i do a lot of printing,,, In Australia i use “Blueprinted” filaments which is pretty good quality for a cheap filament Colorfabb is hard to get here and its bloody expensive..

        Thanks for your information.
        I get lucky to live in the Netherlands, the shipping costs are free when I order one spool.
        And with the 2.2kg spools it’s 30% less in price.

        I’m sure I need to play with some settings (temps and max speed).
        I hope to start this evening with some tests 🙂

            CollorFabb PLA is good material anyway.
            XT can handle a higher temp when it’s printed, this part is a positive thing if InMoof stays for a long day in sunlight.
            So maybe I will use XT for some outside parts and all others with PLA 🙂

    The new printed shaft fits well and it looks that it can handle the rotation.

    So, the new hexagonal shaft / Small_Gear and Servo_adapter files are uploaded 🙂

    I will test this soon and will share a video later this week.

    Marten de Groot posted an update 8 years, 1 month ago

    Instead of a DogBone shaft, I’ve designed a new small Wrist_Gear and servo-adapter and will use a 6mm hexagonal shaft.
    I hope the 6mm hexagonal shaft is strong enough 🙂
    Tomorrow I will print all parts and if it works fine, I will include these parts to the Wrist upgrade set @ Thingiverse.

    Later this day, I hope to finish the last things for the new Wrist DogBone shaft.
    (I need to change some small things to makethe DogBone shaft fit between the small Wrist gear and to the servo DogBone adapter)

    I’ve connect all fishing lines to the fingers and the servo’s.
    All runs more freely and looks OK for me, here the test video with a complete Arm/Hand/Fingers:

      Perry replied 8 years, 1 month ago

      That is awesome. No tensioning spring is the best feature! I guess you could add a tension spring like you had in your single finger tutorial.
      I think this is pretty innovative which begs the question what does the rest of your bot look like?

      • Profile picture of Marten de Groot
        Marten de Groot replied 8 years, 1 month ago

        Hi Perry,
        Yes for sure I will include the springs which I’m using with my Finger_Starter kit.
        This makes programming a closed position more easy and they are to safe the servo mechanical way 🙂

            🙂
            I think after this weekend I will upload all files, which are needed to upgrade the Wrist part and this includes the new ServoBed for the small servo’s and the Wrist servo.
            I can’t see that these smaller servo’s can hold it for a longer period 🙂
            But so far it looks good and including the springs I think it’s safe enough to use them!

      Very nice Marten!
      It’s very interesting to see how you managed the wrist servo, I guess we could add a second servo for wrist abduction. That would be a great extra feature. (Hand Mini breakout Nervo Boards and Nervo boards would need to be transformed and all scripts and gestures as well though…)

    Finally the new ServoBed is done and fits very well.
    For now I’m using a 98mm DogBone drive shaft from a tamiya RC truck.
    Later, I will order this one:

          Once again nice work. It would be great to have a printable shaft for the wrist as opposed to a dog bone. Just another part I would have to wait for when I want to try something late at night. I thought you had a different servo offset in your previous vid and didn’t need the universal joint functionality

            Thanks Perry,

            A printable shaft would be cool, I only think it’s not strong enough !
            And DogBone shafts are very basic parts which are used in RC cars.
            Most local dealers will selling them.

            About the servo, in the first test video I was using a “Low Profile” servo.
            For some reason, these servo’s will not run with a Arduino !

    The Servobed is updated, so tonight I can mount the Wrist servo and measure the distance between the small Wrist-Gear and the servo.
    To finish this Wrist update, I only need to print the servo link.
    Then it’s time to mount the Hand and all the fingers 🙂 (I can’t wait…)

    I’ve decided to make new Wrist Gears to, so all the Finger-fishing lines are more in line with the servo’s !
    The Wrist servo will placed on the Finger servobed and with a axle it will be connected to the small Gear.

        Haha, my fingers are crossed 🙂

        The Wrist servo is blocking the complete way for all fishing-lines.
        With the servo placed on the servobed, it makes it full open.
        So this saves a lot of friction 🙂

      Hello Marten. I came to that exact same conclusion last night while assembling my tendons. They have been very finicky and I am not confident the spring system will hold up. The wrist rotation really plays with the tensions and geometries. I was thinking of a system where the lines ran through the centerline of the wrist. The servo can be moved…[Read more]
