Have you ever thought about making your hero by yourself?
As if people like to make their hero figure by themselves, I made this robot for showing my respect for Jibo (the first social robot)
This robot is simple to make.
Just follow below instruction, If you have any question, feel free to comment.
I will try to help you as detail as possible.

I printed it with 5% infill. It was enough for me. If you are not sure how much do you have to fill in, 20% is fine in general.
Put the WS2812B module into the inner frame and Solder it.
This capacitor helps to be stable. Be careful with colors, +and - direction
Glue it for protecting from unexpected short.
Put the module into the outer circle
In order to connect the LED to the Arduino board, Wire the connector with another wires. I used the striper and nipper.
this process (Soldering wires together) is recommended when it comes to wiring.
Tape it with any insulation tape
PIN 2 will be the location for this LED
Enlarge third hole by using a drill or awl. This prevents the horn from being split.
One bolt of them is slightly longer than I expected. Just make it loose (or just glue it. It will be okay)
Assemble from the head to the body.
The small piece is an alternative of nuts.
I didn’t want to use any extra part.
Because the space in the head is very small.
I cannot hold a nut for make it fasten.
So, I made this small part.
Screw the head motor with the head frame and the small part I mentioned.
This motor will be connected with pin 0 on Servo board. Pay attention to the direction.
The Frame is the first joint part. Its angle is stiff. The pointing side is front.
Be careful the direction
the second motor is connected with pin 1 on the board.
You need to be careful.
It is slightly hard to assemble because the motor must be fasten both sides.
Use the sharp screw to fix it. Please pay attention to the direction.
As you can see. You can assemble it. It has direction.
The cables go through that hole.
Put LED’s wire into the body.
It could be confusing because there are 4 holes.
The intention was “go though behind”.
As we did it, enlarge the third hole with 2mm diameter drill. And screw it.
Cables must go through the wide hole.
Servo Motor Shield
The red board is Audio Spectrum Shield (from Sparkfun)
Arduino nano
Arduino nano expansion
This capacitor helps the power to be stable.
Solder “V+” and “VCC” together.
Solder “pin headers” both Arduino expansion board and the shield.
This Servo Module uses I2C communication.
The shortest cable might be head’s motor (0).
Connect one by one (Body - 1 / Foot - 2).
Use Y Jack for splitting audio source.
If you didn’t install [Arduino IDE], please install it.
If you bought A copied Arduino Nano (Which uses CH340 for communication), you need to install CH340 driver from here
Search “Neopixel” and install Adafruit Neopixel (Thanks Adafruit!!),
Serch “Adafruit PWM Servo Driver Library” and install it
After you plug it, Arduino IDE is going to find a Serial ports, that is the port for your Arduino Nano, It is similar to an Airport. If a airplane lands on, the airport allocates an port to that airplane. We need to let the Arduino IDE to know which port is connected to Arduino board. Select emerging ports (it may not same as above number)
Plug aux cable into your phone or any audio source and play any songs!
Dear Jibo,
I cannot forget the moment when you were introduced to the world.
Thanks to you, many people including myself have been inspired.
I respect you. So I made this robot jusct as people make their hero figures by themselves.
Thanks again, Jibo
Best regards,
