Overview of this book

In this day and age, robotics has been gaining a lot of traction in various industries where consistency and perfection matter. Automation is achieved via robotic applications and various platforms that support robotics. The Robot Operating System (ROS) is a modular software platform to develop generic robotic applications. This book focuses on the most stable release of ROS (Kinetic Kame), discusses advanced concepts, and effectively teaches you programming using ROS. We begin with aninformative overview of the ROS framework, which will give you a clear idea of how ROS works. During the course of this book, you’ll learn to build models of complex robots, and simulate and interface the robot using the ROS MoveIt! motion planning library and ROS navigation stacks. Learn to leverage several ROS packages to embrace your robot models. After covering robot manipulation and navigation, you’ll get to grips with the interfacing I/O boards, sensors, and actuators of ROS. Vision sensors are a key component of robots, and an entire chapter is dedicated to the vision sensor and image elaboration, its interface in ROS and programming. You’ll also understand the hardware interface and simulation of complex robots to ROS and ROS Industrial. At the end of this book, you’ll discover the best practices to follow when programming using ROS.

Chapter 11. Building and Interfacing Differential Drive Mobile Robot Hardware in ROS

In the previous chapter, we discussed robotic vision using ROS. In this chapter, we will see how to build autonomous mobile robot hardware with a differential drive configuration and how to interface it into ROS. We will see how to configure the ROS Navigation stack for this robot and perform SLAM and AMCL to move the robot autonomously. This chapter aims to give you an idea about building a custom mobile robot and interfacing it on ROS. We will cover the following topics in this chapter:

  • Introduction to Chefbot a DIY autonomous mobile robot
  • Developing base controller and odometry nodes for Chefbot in ROS
  • Configuring the Navigation stack for Chefbot and understanding AMCL
  • Working with the Chefbot simulation
  • Interacting with the Navigation stack with a ROS node

The first topic we are going to discuss in this chapter is how to build a DIY (Do It Yourself) autonomous mobile robot, develop its firmware, and interface...
