Introduction: Raspberry Pi Pico Open Remote Control Walking Robot "EasyPico"
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 gather parts.
- Easy to 3D print.
- Easy to assemble.
- Easy to program.
You can check the whole 3D preview by 3mf file.
Supplies

About Kitronik Servo Board 5339
There are in two version.
Current Version (2023/11)
You need USB Connection for moving Robot. Though it is not remote control, it works.
Next Version (It will be release 2024/1)
Perfect remote control possible. You don't need USB Connection.
Kitronik sent me a new version board ahead of time, and I confirmed that it works without USB connection.
Refer to 'Example_Parts_Tool_List.pdf' for the Parts link and more information.

Step 2: Print
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)
Example PLA Setting
- Layer height - 0.2mm
- Infill - 20%
- No generate support
Gcode print files also available. You can check the approximate print time and amount of PLA required.

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.

Thank you for your comment.
The motion is not sufficient, so I hope someone will share the code.

Very nice I am wondering if you can use a pico h for this project instead of pico w

Thanks for comment.
This project operates with WIFI function, so PICO W is required. Unfortunately, it does not work with PICO H.

Ok thank you

If you try using an IR (infrared) connection instead of WiFi, it might also work with PICO H.
I initially thought about using IR, but I opted for WiFi due to its simplicity.

That is a good Idea.
