Building your own mobile robot is becoming easier and easier, thanks to excellent ready-to-use robotic platforms. A good example of such platform is the Adafruit Mini Robot Chassis kit, which comes with a nice robot chassis, two servo motors with wheels and a support-wheel. This makes it the perfect base for all your mobile robot projects.

On the other hand, you now can buy powerful & cheap microcontrollers like the ESP8266 WiFi chip, which is not only easy to use but also comes with onboard WiFi connectivity. This is just the perfect chip to control robots remotely from your computer or mobile device.

In this guide, you are going to learn how to build your own mobile robot based on the Adafruit Mini Robot Rover Chassis Kit, and on the ESP8266 WiFi chip. We are first going to see how to assemble the robot, and how to configure it so it can receive commands via WiFi. After that, we'll see how to control it via WiFi from a nice interface that runs in your web browser. Let's start!
