ROS Programming: Building Powerful Robots

By: Anil Mahtani, Aaron Martinez, Enrique Fernandez Perdomo, Luis Sánchez, Lentin Joseph

Overview of this book

This learning path is designed to help you program and build your robots using open source ROS libraries and tools. We start with the installation and basic concepts, then continue with the more complex modules available in ROS, such as sensor and actuator integration (drivers), navigation and mapping (so you can create an autonomous mobile robot), manipulation, computer vision, perception in 3D with PCL, and more. We then discuss advanced concepts in robotics and how to program using ROS. You'll get a 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. We'll go through great projects such as building a self-driving car, an autonomous mobile robot, and image recognition using deep learning and ROS. You can find beginner, intermediate, and expert ROS robotics applications inside! It includes content from the following Packt products: ? Effective Robotics Programming with ROS - Third Edition ? Mastering ROS for Robotics Programming ? ROS Robotics Projects

Chapter 16. 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...
