Inmoov Robot Build Log
I have started to build on this Inmoov Project in early 2021 with my Ender 3 3D Printer. Here I will updating on how far my project has succeeded. My goal is to complete the top half of the body by the fall of 2021.​
Current Log Build
[As of 3rd Jan 2022]
Completion of the upper torso and right arm
Robby Robot Upper Torso
Robby Robot Right Arm

Building The Head
Pictures of building & programming the head
Inner jaw mechanisms
Jaw Mechanism
This was the initial build of the Head. the parts had taken over 60 hours of continuous 3D Printing. The build time was around 4 hours and I had programmed the head to do basic movements and to use the camera that is built into the eye

Building Right Hand
This was the initial build of the right hand. the parts had taken over 40 hours of continuous 3D Printing. The build time was around 6 hours and there has been a lot of hard precisions that I had to achieve so that the fingers can move freely.

Building The Body
This was the initial build of the right hand. the parts had taken over 100 hours of continuous 3D Printing. The build time was around 8 hours and there has been a lot of elbow grease that I had to place in. I had to use a hot air gun and then hammer the parts to each other. This was a lot of hard work and it surprisingly paid off

Mounting the head to the body with a new neck
This had been the one of the nightly builds where I can make my own neck that is doing more movements that I had preferred. Now the movements was to left right, up down, tilt left right

1st literation of the receiver
This is the first iteration of the receiver that I made so that I can control up to 6 servos using my Flysku Transmitter. I also had a new learning experience on how to use a perf board and how to do basic connections
The board in action

2nd literation of the receiver
This is the second iteration of the receiver that I made so that I can control up to 7 servos using my Flysky Transmitter. I was also able to use the battery as a power bank for the receiver that takes in 5V, by using a step down voltage converter from 11v to 5v. Now the whole unit can be controlled by one battery

Building the Right Bicep
( Commencing The Completion Of The Whole Right Arm )
The Bicep of the robot has been one of the complex parts that I had to hurdle. It had also consisted of modding a servo and doing of Surface Mount Diode Soldering that had to be done. Due to the complexity, I had broken the bicep build into 3 objectives.
Objective 1-
Building the structure of the Bicep
This objective had just caused me to build the rough structure of the bicep and finding out how the bicep actually works. Moreover, the parts where hard to place in as due to not enough clearance.
Objective 2-
Modding The Servo Motor
This was personally one of the most hardest part of the build of the bicep as I had to work with very small and sensitive to heat parts, so I hard to quick and efficient when soldering the parts in the servo.
Essentially I had to move the potentiometer from the casing to outside, solder a couple of resistors for more torque power and change the gears for more torque power
Objective 3-
Attaching The Hand To The Bicep
In this objective, I had to attach the right hand and bicep so that it can form a right arm. This had to be easiest part of the bicep build as it had taken less than 2 hours to do it.
Objective 4-
Trying the Arm
In the this objective I had just to do some minor works on and also try the receiver on the hand that I had created earlier on. Fortunately everything was working and was responsive.

Building the Right Bicep
Building the Upper torso and the the casing
This was the rough internal skeleton that I had printed for over 120 hours and crafted for over 52 hours and placed it painstakingly on the robot's head and calibrated to so that the upper torso would be stable. I also printed a mount that Is able to make the robot to stand on a speaker tripod
I had to load up a custom Raspberry PI environment and also placed a receiver so that I can test all the functions properly. Moreover, I also to check the impending forces just to make sure the robot does not fall over
This was the complete upper torso with its own embedded name, Robby, there is a hold on the lower end so that a Xbox kinect camera can be placed for human tracking; that will be stated more on a another log
