Mastering ROS for Robotics Programming - Second Edition

By: Jonathan Cacace, Lentin Joseph

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 9. Interfacing I/O Boards, Sensors, and Actuators to ROS

In the previous chapters, we discussed different kinds of plugin frameworks that are used in ROS. In this chapter, we are going to discuss the interfacing of some hardware components, such as sensors and actuators, to ROS. We will look at the interfacing of sensors using I/O boards, such as Arduino, Raspberry Pi, and Odroid-XU4 to ROS, and we will discuss interfacing smart actuators, such as DYNAMIXEL, to ROS. The following is the detailed list of topics that we are going to cover in this chapter: 

  • Understanding the Arduino-ROS interface
  • Setting up the Arduino-ROS interface packages
  • Arduino-ROS examples: Chatter and Talker, blink LED and push button, Accelerometer ADXL 335, ultrasonic distance sensors, and Odometry Publisher
  • Interfacing a non-Arduino board to ROS
  • Setting ROS on Odroid-XU4 and Raspberry Pi 2
  • Working with Raspberry Pi and Odroid GPIOs using ROS
  • Interfacing DYNAMIXEL actuators to ROS
