I tried to make a robot that everyone can enjoy.
3D Data, How to Make, and Code are open to the public.
You can put it together with parts that cost around 7000 Japanese yen (70 US dollars at ¥100/$, excluding PLA filament).
The power supply is designed to be safe with AAA batteries.
For example, how about as a material for STEM/STEAM education?
Or simply enjoy 😊
Concept is Easy
- Easy to 3D print.
- Easy to gather parts.
- Easy to assemble.
- Easy to program.
Only 4 STL files required
- Head & Body
- Arm x2 (left and right are the same)
- Legs
- Covers
Individual Parts
If you have a small 3D printer or prefer to print each part separately, I also offer separate STL files available.
- Individual_Parts.zip (28 files)

Kitronik Servo Board 5339
There are in two version.
https://kitronik.co.uk/products/5339-simply-servos-for-raspberry-pi-pico
Previous Version (2023)
You need USB Connection for moving Robot.
Though it is not remote control, it works.
Current Version (2024)
Perfect remote control possible. You don't need USB Connection.
Kitronik sent me a new version board last year
and I confirmed that it works without USB connection.
Unfortunately, it's hard to confirm if the board you're getting is the current version.
It might be best to ask Kitroniks.
Assemble
Refer to 'How To Make_EasyPico.pdf' for complete instructions.
Program
There are sample remote control code files.
Save the following 6 files in your PICO:
+-- main.py
+-- Config.Change.py (Save as "Config.py" and adjust for your environment)
+-- LedAction.py
+-- ServoAction.py (for exercise)
+-- ServoAction2.py (for walking forward)
+-- SimplyServos.py (Same as this )
Printer
-- Anycubic Mega-S
Filament
-- Anycubic PLA Black
-- eSUN PLA+ Olive Green
Example PLA Setting
-- Layer height - 0.2mm
-- Infill - 20%
-- No generate support
Share your code
Sample Code is only walking forward and exercise.
I am happy if you share your code to public.
Turn right, left and backward movement is attractive.
Thank you for
- idea of motion. PLEN:bit and OTTODIY
- share of base remote control code. Michael.
- quick and sincere response. KITRONIK Support.
