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 ?

Chapter 27. Building an Autonomous Mobile Robot

An autonomous mobile robot can move from its current position to the goal position autonomously with the help of mapping and localizing algorithms. ROS provides some powerful packages to prototype an autonomous mobile robot from scratch. Some of the packages used in an autonomous robot are the ROS navigation stack, gmapping, and amcl. Combining these packages, we can build our own autonomous mobile robot. In this chapter, we will see a DIY autonomous mobile robot platform that works using ROS. This project is actually the updated version of the work mentioned in my first book, Learning Robotics Using Python, Packt Publishing (http://learn-robotics.com). In this chapter, we will mainly go through designing and building the simulation of a robot, then the hardware of robot, and finally the software framework. The chapter will be an abstract of all these things, since explaining everything in a single chapter will be a tedious task.
