1. Overview

I made a quadruped robot with four axes using M5Atom S3 of the M5Stack series
NX21_1

2. Componets

1)M5Atom S3
2)Servo TowerPro SG92R x4

4.Motion

In order to advance on four axes, ingenuity is required.

Right turn (left turn is the opposite action)
NX21_5

5.Sketch

I wrote a detailed Sketch on Github, so please refer to it.

6.Motion check

This time, in addition to forward, backward, left and right turns, we also added a mode that measures the distance with PSD and operates.
Also, change the movement of raising the front leg and the expression of the face. blink eyes
