• After installing Fred’s left Bicep, I asked him to record a video for me.
    This went well until he went to point to the virtual white board on his right side.
    Now he not talking to me 🙁
    So now I’m working on his right arm 🙂

  • I had a bit of a play with a few servos to see how they performed when the voltage to them started to get a bit low.

    It’s surprising just how much the current increases when they start to struggle.

  • Ray Edgley posted an update 6 months, 1 week ago

    I made Fred a happy robot with the addition of his left bicep, right up until he woke up his virtual white board was on his right side. 🙂

  • Fred’s been at me for a while now on getting him some Arms.
    Here is the start of the left Bicep.

  • The final part of Fred’s Left Shoulder.
    Here we set the feedback pots position and test it all out with MRL.

    It’s all coming together 🙂

  • Ray Edgley posted an update 7 months, 1 week ago

    I recently got a new toy.
    I don’t normally post unboxings in here, but this is so handy when setting up your servos.

    This servo tester is great for positioning servos and testing the range before connecting the servos to the servo drivers and fire up MRL.
    I also opened this one up to see what was inside it.

  • In this video we will build and add the bicep rotator to Fred’s Left Shoulder.

  • Part 2 of Fred’s Shoulder.
    More worm drive fun and games 🙂

  • Since Fred was insisting, I started on his Left Shoulder.
    This is the start of the new version of the shoulder with the ball bearings.

    Just for a laugh, I turned on the webcam to record Fred 🙂

  • Ray Edgley posted an update 8 months ago

    When your building a robot, sometimes, you need to sense a signal or a voltage that is well over the rating of your input.
    This is not a real problem, because you can use a voltage divider to drop the voltage down a proportional amount.

    I did this with Fred’s battery monitoring inputs, where the Battery voltages can be…[Read more]

    The shoulders in Fred are standard, latest version from this site.
    The new ball bearing setup are much smoother.

    Continuing with Fred’s Right shoulder, during this I find an issue with the pot and have to replace the pot.

  • Ray Edgley posted an update 9 months, 1 week ago

    In this video, I print out and assemble more components for Fred’s shoulder.
    I also mount the shoulder assembly onto Fred’s upper torso and set the feed back pot position.

  • Today, I start on Fred’s Right Shoulder.
    This updated version of the Inmoov shoulder has bearings in it 🙂

  • Continuing with the Fred’s Brain series, this time I look a speech services.
    Both TTS and STT

  • So last week I unboxed a new Raspberry Pi 4 with 8G of RAM.
    This week, I setup the OS and install MyRobotLab on it.

  • In this video Part 3 of Fred’s Brain, we continue looking at MyRobotLab and how we use the services to setup and control Fred.

    • I really enjoy watching your videos Ray. The way you explain things is great. However I have a confession. I have gone over to the “dark side” that is ARC. I am now running EZ-B controllers and find the ARC software much more intuitive and simpler to work with. I have modified the Nervo Board to suit the new setup.
      Keep up the good work. Warren

      • In the world of robotics, there is no dark side, unless you plan to have your robots destroy other robots ect.
        There is only different 🙂

        In any case, keep on building and posting your progress 🙂

        • He won’t be destroying other robots. His main role is to teach my students about Robotics and AI. His secondary role will be to help teach kids sign language. The second part is not proving straightforward but, I enjoy a challenge. 😉

          • I do remember seeing another design of hand created for the Inmoov robot by a builder that allowed side to side motion of some of the fingers.
            It was posted on Thingiverse.
            It does require more servos 🙂

  • I needed to know what the battery voltage was and also had some issues with the MPU6050 running with the Raspiberry Pi 4.
    To I added one to the I2C port on the Arduino Nano.

    Part two of Fred’s Brain.
    In this video we look at the Servo Service in MyRobotLab and how we set them up on our robots.
    Fred has quite a number of servos, and once the arms and hands are attached, there will be a lot more 🙂

    • Great video Ray. I wish I was as confident at writing code.

      • Keep in mind, I’ve been playing with this for 6 years now 🙂

      Fred is going great and you have really helped a lot understand how to assemble an inmoov. It also shows, one should feel completely comfortable modding it. This child needs to mutate and change over generations to survive.

      • Modding also makes you go further in to the learning of how things work 🙂
        Good news is there are a lot of Inmoov builders that bring knowledge to the group so we can all learn.

      • Hello Steve,

        The following quantities are for each leg, so you will need to double them for both legs.

          Theses could have been 25 mm long, however only had 20 mm and 40 mm long on hand.

  • Since the last video generated some interest in my build of the InMoov robot (Fred) I thought I would pull off one of his arms and give you a look inside.

    • Great job Ray. The print look outstanding.

      • And that was done with what was then a very cheap CTC printer back in 2017.
        The printer also had errors in the calibration of the X and Y axis, so all joints had to be filed to make them fit.

        So even with a crappy print, you can still build a working Inmoov 🙂
