## 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.
