How to Make Quadruped Robot With Use Esp8266 and Sg90 Servo

MiniQ - The World’s Simplest Quadruped Robot

MiniQ is a beginner-friendly, Wi-Fi-controlled quadruped robot powered by the ESP8266 (Wemos D1 Mini). Designed to be the "world's simplest" robot dog, it utilizes a 1-DOF (Degree of Freedom) design per leg, eliminating the need for complex inverse kinematics or heavy mathematics.

The robot hosts its own web interface, allowing you to control it directly from a browser without installing any apps.

Bill of Materials (BOM)

Microcontroller: Wemos D1 Mini (ESP8266)

Actuators: 4x SG90 Micro Servos

Power: 3.7V LiPo Battery

Charging: TP4056 Charging Module (with battery protection)

Voltage Regulation: 5V Step-Up (Boost) Converter

Capacitor: 1500µF (placed on servo power line to handle startup current)

Switch: Slide switch

Most important thing voltage booster only power for Servo and connect a big capacitor on servo power line. And than battery power directly wemos d1 mini on 5v pins. Other wiring simple to seen on schematic.

Script released on my github. You can download and easily upgrade. Also how to this. I am telling youtube video tutorial. More information go checkout
