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.

About Kitronik Servo Board 5339

There are in two version.

Old (or Current depend on shop) Version

 You need USB Connection for moving Robot. Though it is not remote control, it works.

New Version (released 2024/3)

 Perfect remote control possible. You don't need USB Connection. 

Refer to 'Example_Parts_Tool_List.pdf' for the Parts link and more information.

Refer to 'How To Make_EasyPico.pdf' for optional tools and complete instructions.

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.
