Overview of this book

The ESP8266 Wi-Fi module is a self-contained SOC with an integrated TCP/IP protocol stack and can give any microcontroller access to your Wi-Fi network. It has a powerful processing and storage capability and also supports application hosting and Wi-Fi networking. This book is all about robotics projects based on the original ESP8266 microcontroller board and some variants of ESP8266 boards. It starts by showing all the necessary things that you need to build your development environment with basic hardware and software components. The book uses the original ESP8266 board and some variants such as the Adafruit HUZZAH ESP8266 and the Adafruit Feather HUZZAH ESP8266 . You will learn how to use different type of chassis kits, motors, motor drivers, power supplies, distribution boards, sensors, and actuators to build robotics projects that can be controlled via Wi-Fi. In addition, you will learn how to use line sensors, the ArduiCam, Wii Remote, wheel encoders, and the Gripper kit to build more specialized robots. By the end of this book, you will have built a Wi-Fi control robot using ESP8266.

Building an ESP8266 Robot Controller

This chapter will guide you to build an ESP8266-based simple Robot Controller that can be used to control the movement of the Romi Robot Chassis introduced under building the Romi Robot section. The Robot Controller consists of four movement-related push buttons that can be used to control the movement of the Romi Robot in four directions: forward, backward, left, and right. A Wi-Fi network is used to connect the Robot Controller with the Romi Robot, and a Blynk bridge is used to connect both of them for handling bi-directional data communication. This Robot Controller is very similar to a RC Remote Controller (Figure 6.1) but uses a Wi-Fi network to communicate with the robot instead of radio frequency:
