Mastering ROS for Robotics Programming

By: Lentin Joseph

Overview of this book

The area of robotics is gaining huge momentum among corporate people, researchers, hobbyists, and students. The major challenge in robotics is its controlling software. The Robot Operating System (ROS) is a modular software platform to develop generic robotic applications. This book discusses the advanced concepts in robotics and how to program using ROS. It starts with deep overview of the ROS framework, which will give you a clear idea of how ROS really works. During the course of the book, you will learn how to build models of complex robots, and simulate and interface the robot using the ROS MoveIt motion planning library and ROS navigation stacks. After discussing robot manipulation and navigation in robots, you will get to grips with the interfacing I/O boards, sensors, and actuators of ROS. One of the essential ingredients of robots are vision sensors, and an entire chapter is dedicated to the vision sensor, its interfacing in ROS, and its programming. You will discuss the hardware interfacing and simulation of complex robot to ROS and ROS Industrial (Package used for interfacing industrial robots). Finally, you will get to know the best practices to follow when programming using ROS.

Chapter 9. Building and Interfacing Differential Drive Mobile Robot Hardware in ROS

In the previous chapter, we have discussed about robotic vision using ROS. In this chapter, we can see discuss how to build an autonomous mobile robot hardware with differential drive configuration and how to interface it into ROS. We will see how to configure 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.

You will see the following topics in this chapter:

  • Introduction to Chefbot: a DIY autonomous mobile robot

  • Flashing Chefbot firmware using Energia IDE

  • Discussing Chefbot interface package in ROS

  • Developing base controller and odometry node for Chefbot in ROS

  • Configuring Navigation stack for Chefbot

  • Understanding AMCL

  • Understanding RViz for working with Navigation stack

  • Obstacle avoidance using Navigation stack

  • Working with Chefbot simulation

  • Sending a goal to the Navigation...
