1. Overview

I made a hexapod robot with M5Stamp S3 using ESP32 C3 in M5Stack series, round LCD and AI camera UnitV and IMU MPU6050.

2. Components

1)M5Stamp S3
2)Servo TowerPro MG90D x18
3)Battery Lithium Ion 16340(With protection circuit)x2
4)PCA9685 Servo driver PCB(PONDA's PCB)
5)DCDC board LXDC55
6)AI camera UnitV
7)IMU MPU6050
8)ROund LCD Switch Science site

The wiring is as follows.

4.Control by JoyC

This time, the control uses the JoyC with M5StickC.


I wrote a detailed M5Stamp S3 sketch and UnitV Python code on Github, so please refer to that.

6.Motion check

The movement of the leg this time is calculated by inverse kinematics. At first, I used spreadsheet software outside the robot for calculations, but finally implemented it in M5Stamp S3 so that it could be calculated in real time.
