1. Overview

I made a quadruped robot with M5 COreS3 of the M5Stack series

2. Componets

1)M5 CoreS3
2)Servo SG90 x12
3)Battery NiMH 1.2V x 4 = 4.8V
4)PCA9685 Servo Driver board

The wiring is as follows.

3. Functions

1)Walking Left/right/front/back
2)Attitude control with JoyC controller
3)Leveling using IMU
4)Face tracking using the M5CoreS3 camera

4. Assembling

The interior is as shown in the photo.

5.Motion

It can walk, control posture, and keep horizontality using an IMU.

6.３D data & Source code

I've put the 3D data (STL) and source code on GitHub.
