ESP8266 Robotics Projects

By: Pradeeka Seneviratne

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.

Preface

Using chassis kits and accessories to build robots


Chassis kits provide everything to build robots with most microcontroller boards. You'll use the following chassis kits to build projects.

Mini 3-Layer Round Robot Chassis Kit

The 3-Layer Mini Round Robot chassis Kit (Figure 1.12) includes the following things you need to build the shell of a two-wheel drive mobile platform robot:

  • Two drive motors
  • Two wheels
  • One plastic caster ball
  • Anodized aluminum frames and all mounting hardware for assembly

You can purchase a kit from Adafruit Industries (https://www.adafruit.com/product/3244) to work with projects that will be discussed in Chapter 2Building a Mini Round Robot with Original ESP8266, Chapter 3Using Encoders, and Chapter 4, Building a Mini Round Robot with the Feather HUZZAH ESP8266:

Zumo chassis kit

The Zumo chassis kit (Figure 1.13) allows you to build tracked robots that run on continuous tracks instead of wheels. Tracked vehicles can be used for:

  • Construction vehicles
  • Military armored vehicles
  • Unmanned ground vehicles

The Zumo chassis kit includes the following things:

  • Zumo chassis main body
  • 1/16" black acrylic mounting plate
  • Two drive sprockets
  • Two idler sprockets
  • Two 22-tooth silicone tracks
  • Two shoulder bolts with washers and M3 nuts
  • Four 1/4" #2-56 screws and nuts
  • Battery terminals

You can purchase a kit from Pololu (https://www.pololu.com/product/1418) to work with the project that will be discussed in Chapter 5, Line-Following Zumo Robot:

Romi chassis kit

The Romi chassis kit (Figure 1.14) includes the following things you need to build a two-wheel drive robot:

  • One black Romi chassis base plate
  • Two mini plastic gearmotors (120:1 HP with offset output and extended motor shaft)
  • A pair of black Romi chassis motor clips
  • A pair of white 70 × 8 mm Pololu Wheels
  • One black Romi chassis ball caster kit
  • One Romi chassis battery contact set

You can purchase a kit from Pololu (https://www.pololu.com/category/202/romi-chassis-and-accessories) to build the project that will be discussed in Chapter 6, Building an ESP8266 Robot Controller:

Mini robot rover chassis kit

The mini robot rover chassis kit (Figure 1.15) includes the following things needed to build the shell of a two-wheel  drive robot:

  • Two wheels
  • Two DC motors in MicroServo shape
  • One support wheel
  • One metal chassis
  • One top metal plate with mounting hardware

You can purchase a kit from Adafruit industries (https://www.adafruit.com/product/2939) to build the project that will be discussed in Chapter 7, Building a Gripper Robot.

Rover 5 robot platform

The Rover 5 robot platform (Figure 1.16) allows you to build a four-wheel drive tracked robot. The kit includes the following things:

  • Adjustable gearbox angles
  • 4 independent DC motors
  • 4 independent Hall-effect encoders
  • Thick rubber tank treads
  • 6 x AA battery holder
  • 10 Kg/cm stall torque per motor

You can purchase a kit from Pololu (https://www.pololu.com/product/1551) to build a project that will be discussed in Chapter 8, Photo Rover Robot.

Wheel encoder kit

The wheel encoder kit (Figure 1.17) allows you to measure the speed or distance that the chassis travels. You'll learn how to connect the wheel encoder kit to any wheeled robot in Chapter 3, Using Encoders:

Parallel Gripper Kit A - Channel mount

A gripper can be connected to a robot to allow grip objects. Figure 1.18 shows a Parallel Gripper Kit assembled. You will need any standard size Hitec or Futaba servo to integrate with the gripper kit. You can purchase one from SparkFun Electronics (https://www.sparkfun.com/products/13178):
