ROS Robotics Projects - Second Edition

Overview of this book

Nowadays, heavy industrial robots placed in workcells are being replaced by new age robots called cobots, which don't need workcells. They are used in manufacturing, retail, banks, energy, and healthcare, among other domains. One of the major reasons for this rapid growth in the robotics market is the introduction of an open source robotics framework called the Robot Operating System (ROS). This book covers projects in the latest ROS distribution, ROS Melodic Morenia with Ubuntu Bionic (18.04). Starting with the fundamentals, this updated edition of ROS Robotics Projects introduces you to ROS-2 and helps you understand how it is different from ROS-1. You'll be able to model and build an industrial mobile manipulator in ROS and simulate it in Gazebo 9. You'll then gain insights into handling complex robot applications using state machines and working with multiple robots at a time. This ROS book also introduces you to new and popular hardware such as Nvidia's Jetson Nano, Asus Tinker Board, and Beaglebone Black, and allows you to explore interfacing with ROS. You'll learn as you build interesting ROS projects such as self-driving cars, making use of deep learning, reinforcement learning, and other key AI concepts. By the end of the book, you'll have gained the confidence to build interesting and intricate projects with ROS.

Introduction to single-board computers

In the previous sections, we looked at a series of microcontroller boards with varied features, which have all of the components embedded in a single chip. What if you want your robot or drone to perform modern-day computations for path planning or obstacle avoidance? Microcontroller boards help us read sensor signals and control the actuator signals, provided they follow simple math libraries for understanding and processing sensors.

What if you want to perform intense computation, store incoming sensor values over time, and then perform computations on such stored values? That is where SBC comes into play. SBCs can be loaded with an OS and could perform computations like a modern-day desktop, in a small form factor setup. They can't immediately replicate a modern-day computer as desktop computers nowadays are attached to additional...
