Custom InMoov PDB

In my quest to keep wiring neat (which it is not at this time), I wanted to create a board that would help minimize the amount of wiring needed.

So I create a Power Distribution board that will take all servo inputs from 2 EZ-B v4/2’s and then isolate and output the signal wire to the EZ-B’s.  The power will be handled by the PDB.

The PDB will also have two LED’s allowing me to see that the PDB is receiving power to each side.  There will also be a 4 pin header that is for Ground so that the servos are running from the same ground, 2 Pins can be routed to each EZ-B.

Eventually the goal will be to make one Main Board to handle the entire robot.  But for now I am doing it in small phases until I have everything the way that I want it to be.

InMoov Update – Neck Tilt Demo

So I haven’t had many updates here on my InMoov Robot build as the build is mostly complete, I still have the hands to complete and some misc. small things to do.

I wanted to get started on the electronics as seeing it move and talk is very motivating.  Today I spent the time to get one should partially wired and the servos controlling the ability to tilt the neck.

Here is a short 1 minute 10 second video giving a short demo on the neck tilting as well as some speech.  Since I had the shoulder partially wired, I also added some movement there to show its range of motion.

InMoov – Assembly Progress

Over the past 1-2 weeks my focus has been on 3D Printing the arms.  I started some of the assembly on the right arm as well.  Below you can see the progress of this.  I should have the arms mostly printed by the end of 12-27-17.

InMoov – Fusion 360 Renders

InMoov was created using SketchUp, however I am not familiar with using this application and I seem to have difficulties when I try to use it.

Over the past couple weeks I have been using a few programs to bring InMoov to Fusion 360 mostly for assembly purposes.  Here are a couple renders showing the progress.

InMoov – Head nodding test

I installed the neck and head on my InMoov Robot.    I reprinted the pistons that move the head.  I have to make some adjustments still but I did some basic functionality testing.  See below for an image with the head and shoulders attached to the upper torso.

Also see a video of testing the basics of head nodding.  I am only using a servo tester for this movement and will at some point have it controlled by a micro controller or possibly a small computer.

InMoov Eye Movement Test

Now that I have managed to get the head mostly assembled I decided to use an RC Servo tester running at 6 Volts to test the eye movement.  I have tested both the up and down movement as well as left and right.

I still have some fitment to do as there is some rubbing going on, but that will be fixed before the final assembly.

InMoov Robot head assembled

I have been working on building the InMoov Robot created by Gael Langevin, you can read move about it here:  http://inmoov.fr/.

I have been focused mostly on gathering all the electronics, nuts, bolts, wire and so on.  While I have been waiting for parts to arrive I have been 3D Printing as many parts as I can per day.

Below we have a few images showing some of the assembly of the eyes.  As you can see each eye has a camera in it.  The camera is a Hercules HD Twist that I purchased directly from Italy as I couldn’t find any available in the USA.

InMoov Shoulder Assembled

I have 3D Printed the InMoov Shoulders and have assembled them.  One is fully assembled and the other is partially assembled as I am awaiting some 6mm Sling Shot Ammo that is being used to create the bearings.

Below are a couple images of the shoulder.

InMoov Head Assembly

I finally started on the InMoov Robot I mentioned earlier on.  I started by ordering much of the electronics, screws and so on.

While waiting for the electronics I started to print the parts to assemble the head structure.  Below are some images of the head pieces loosely assembled.  There is some fitting and filing that will be needed and will get done as the project progresses.

All white and black parts were printed with Makerbot PLA and on one of 2 Makerbot 3D printers.   The printers used are the Makerbot Replicator Mini + and the Makerbot Replicator +.

The Orange parts used for the ears are printed on a Monoprice Mini Select v2.  I am still experimenting with that printer, I have it printing nice but the layer adhesion is not as good as the Makebot.  These parts are just test prints and will be later printed on the Makerbot printers.

InMoov “Finger Starter” 3D Printed Finger

Recently I discovered the InMoov Robot and after watching many of the videos, reading as much as possible, I decided I would download the Finger Starter STL Files and give this a try as I have a servo that would work and I have an Arduino Uno waiting for the intended project that I have yet to start.

This was a really quick project once the Finger parts were printed.  I had to go buy some fishing line for the tendons, I just bought some 80lb line for this as this is not meant to be used for anything other than to give this project a look.

After giving this a try (see video below), I have decided that I am going to move forward and build the InMoov Robot and use it to increase my Robotics knowledge.  With some luck it will help me with the Humanoid Robot I am working on, and yes I am going to continue and finish the Humanoid.
