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 – External Potentiometer with Quick Disconnect

After I removed the Potentiometers from the HiTech HS-805BB Servos I decided to make them with a quick disconnect making for easy replacement if needed.  For this I just used a servo extension and cut it in half, I then put half on the servo and have on the potentiometer.  I also had to reverse the polarity on a few of the potentiometers that will work in sync with another in various parts of the robot.  To do this I just switched the two outside wires on the potentiometer.

Below is a photo showing them all soldered up and complete.

InMoov – Remove Potentiometer from HS-805BB

To accurately measure the movement of the limbs and other parts of the InMoov Robot it is important to remove the Poteniometer from some of the servos to relocate it externally.

To do this the easiest way is to de-solder the motor from the board inside the servo.  HiTech uses a lot of glue to hold the motor in place.  Trying to force the motor free typically results in broken boards.

I used a hi-temp solder gun and a solder sucker to accomplish this.  Below are a few photos showing this.

InMoov – HS-805BB Servo Stop Removed

One of the things I needed to do was to remove the servo stop inside of the HiTech HS-805BB Servo.  This stop is molded onto the larger gear or the Output gear.  This only allows for a 180 degree rotation.  The goal here is to make the servos rotate continuously as we will set the limits within the software at a later time.

Here are a few photos of the gears and the stop that I will carefully cut off with a hobby knife.  The one thing that is important is to be sure each gear goes back where they are before assembly, also there are 2 steel pins that are different sizes that need to be in the correct location.

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.
