Mini 4X4 Robot

This is a simple 4X4 wheeled robot that is powered using 4 N20 motors. An MX1508 motor driver is used to drive the motors, other similar motor drivers can also be used.

An ESP8266 microcontroller is used to control the robot via a web page-based interface that is hosted on the ESP microcontroller itself so the controlling device does not need any control app installed.
