    Starting with MRL_Nixie, the WebKitSpeechRecognition allows for a wake work that can be used to restart the Speech Recognition.
    That would be a feature in Inmoov2.
    Wake words are not supported in the Manticore version.

      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

    That Amps rating is the Maximum the Power Supply Unit (PSU) can supply, the voltage is the one that can blow things up.
    You want the 6V output, most of the gear used in an Inmoov will tolerate a 6V supply, most don’t like going too low.

    The major consideration is the ability to handle the tension applied.
    When you consider the pulling force required, it is quite understandable.
    The diameter is not anywhere near as important.

    This time he;s talking about the power of rotation in part 4 of the Walking Robot series.

    These are used in servos, cruise controls, industrial ovens, and pressure control systems.
    Here is a video where Fred explains how they work.

    I was thinking more of how you got the tracking software working 🙂
    I’ve got one of Fred’s eyes with a camera in it connected to a Raspberry Pi and servos working to move the eyes, but haven’t done anything on image processing or tracking.

    This one goes into the speed at which the various leg joint will need to rotate at for a normal walking gait.

    Still working on the modified head, Last week I mounted the Raspberry Pi in the head, Friday I release the video on mounting the SMPS for the pi and connecting it to the PCA9685, the week after that is testing and some very basic programming.
    Then i start the walking robot series I hope.
    Where i plan to motorize the legs, this will not be an easy task.

    • Hi. Its been a long absence because of covid. I’m back and will continue.
      I have to reprint one of the pistonanticlock screws that go into the arm because the old one was angled a little. Then I plan to connect a Pi to the head and replace both arduinos with something that can handle multithreading. What about you?

      • I’m re-building the upper torso and shoulders.
        My old printer was not well calibrated and I had a lot of dimensional inaccuracies.
        With my newer printer, it’s now accurate, and since the stand for Fred’s new head is not that good, I’m using the upper torso as a stand 🙂

  • Ray Edgley posted a new activity comment 1 year, 1 month ago

    The temptation to print multiple parts at one on the big bed is great, but a failure in on can result in the failure of all the prints on that bed 🙁

    There is a function within MyRobotLab (MRL) to send email
    http://myrobotlab.org/service/Mail
    There is no reason why you can\’t add this functionality to your robot, once you have done that, Please let everyone know how you went about it!

    Have you worked out what bearing sizes you need yet?
    and have you uploaded the stl files yet?
    Curious minds beg to know….

    It looks good so far.

    • Hay Ray,, Sorry for the late reply but I just noticed your message which is weird,, I’m sure it wasn’t there before– ,,, anyway Han’s Tracked down the Main Bearing a while ago
      Main Bearing is – 45mm x 55mm x 6mm – the small bearing is 8mm x 16mm x 5mm which is slightly smaller than Han’s bearing,,, I’ll be using the 16mm x 8mm x5mm in a few of…[Read more]

    To my knowledge, there is no complete design for legs yet, Bartods appear to be the furthest along so far.

    I used 3mm line trimmer line from the hardware. its cheap and works well

    • That’s a great idea,,,,, I found knitting Needles in the $2 Shop,,,which are 2.8mm and $2.50 a set,,,, I didn’t even think of pulling a bit of cord off my whipper snipper,,,, lol

      • Oh Yeah that’s right,,, I kept with the Knitting Needles because of the Type of Plastic—It’s Extremely hard you can use on Micro Lathe or Drill Press for Shaping ( not just for finger pins) I’m 99% sure it’s Acetate plastic,,,,

    Where do we get the nuclear power source? That will solve the battery issues 😉

  • Ray Edgley posted a new activity comment 3 years, 10 months ago

    Thank you Perry, down loaded them now and will fire up the 3D printer in the morning. Like the look of your robots back as one piece, did you print that as one piece or did you join multiple pieces?, looks very good.

  • Ray Edgley posted a new activity comment 3 years, 11 months ago

    When a user needs help, it helps if there is only one type of robot to support.
    That way there is no confusion and a lot of people can help you.

    Once you start to go down a different design path, there is not as much help so you have to learn more yourself.
    This not discouraged, but in the beginning, it is advised you stick to the standard list of parts.

  • Ray Edgley posted a new activity comment 3 years, 11 months ago

    You are soooo right, I forgot about that.
    Will look into it when I get on him 🙂
    Maybe even some gold lightning emblems on the side of the head 🙂

    The HAT on the PI is the Adafruit 16 Channel servo driver. Also breaks out the Pi Header and is where I grabbed the 5V from to run the other Pi.

    Your Welcome….

    It is possible to fit the third one and then i still have to work out how I want to split the processing load across them.
    As Gael said somewhere on this site, the RPi even the Model 3 still is not quite powerful enough, but they are cheap enough to add multiple so speed up processing, paralleled processing if you will…

    • You could put one PI in the body to connect to the Kinect or just give him a gut feeling. Nice HAT on the PI.

    2 out of 3 Raspberry Pi 3’s installed in the head.

    • That’s alot of pi! Is fitting a third in there possible? Looks great though, very clean setup in that limited space.

    If you have a look in the STL Parts Library located in the Gallery.

    InMoov body parts library :

  • Ray Edgley posted a new activity comment 4 years ago

    You need the recommended 3 shells for strength.
    Running with 1 shell will reduce the filament usage and reduce the print time.
    If the guy said the dimension will be messed up, then he doesn\’t have his slicer program setup correctly.
    Most likely over extruding.

    Looks can be deceiving, but thanks for the complement.

    The shoulder pieces are probably the best parts on the whole robot, I’m more pleased at getting the ribbon to work through the bicep gear.

    Some of the earlier pieces had real bad banding, turns out a spacer i fitted to the top of the Z axis screws to reduce the banding actually made it…[Read more]

  • Ray Edgley posted a new activity comment 4 years ago

    Because there are so many types of 3D printers and slicing software out there, when asking a question like this, it would pay to list the 3D printer make model and the slicer software and version.

    That way someone with the same slicer may be able to help you out.

    This video upload is in response to lorn Campbell query as how it works with the Bicep rotate.
    My recommendation for anyone wanting to do the same thing, would be to use a ribbon with more than 16 conductor and spit the extra across the power wire.
    I used 3 for the servo power 6 Volt and 3 for the servo power 0 Volt, this may not be quite enough,…[Read more]

    The cable relative to the shoulder moves in the gap, the cables relative to the bicep are stationary. The elbow piston clears the ribbon cable by a 2 mm inside the gear, gets a bit closer outside the gear on the bicep end but still clears it just.

    Success,
    Mounter 16 channel PWM Servo driver in the left bicep.
    Also added a small SMPS buck converter in the power supply line to allow for later increasing the a 12V or higher battery system.
    Tripled up the wires for the power supply to cope with the current draw of the servos.
    Only need to sort out a connector for the power in the shoulder and…[Read more]

    Running a 16 way ribbon through the Bicep Rotator is tight, but it is doable.
    Held in place with CA glue.

    Coming up on 6 weeks, the Top Stomach parts have been the biggest challenge so far.
    Parts were very tight, then one of the wire came off the servo pot, worked during testing, but not after assembly. Bummer.

    • Perry replied 4 years ago

      I am unable to snake my wires through there. The piston interferes. I have them bundled though and might have to unbundle them so they can fit. I am using servo extension leads though and not ribbon cable.

      • Wow, the cables fit through the gap. What happens when you rotate the arm? The arm cables have always been an issue on my InMoov, have run the forearm & hand in sleeving externally, but the shoulder cabling is still a mess.
        Great pictures, looking really good Ray
