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

In the last two chapters, we discussed different kinds of plugin frameworks that are used in ROS. In this chapter, we are going to discuss interfacing of some hardware components, such as sensors and actuators to ROS. We will see interfacing of sensors using I/O boards such as Arduino, Raspberry Pi, and Odroid-C1 to ROS, and also discuss interfacing of smart actuators such as Dynamixel to ROS. Following is the detailed list of topics we are going to cover in this chapter:

  • Understanding the Arduino-ROS interface
  • Setting up the Arduino-ROS interface packages
  • Arduino-ROS ,example-Chatter and Talker
  • Arduino-ROS , example-blink LED and push button
  • Arduino-ROS , example-Accelerometer ADXL 335
  • Arduino-ROS, example-ultrasonic distance sensor
  • Arduino-ROS, example-Odometry Publisher
  • Interfacing a non-Arduino board to ROS
  • Setting ROS on Odroid-C1 and Raspberry Pi 2
  • Working with Raspberry Pi and Odroid GPIOs using ROS
  • Interfacing Dynamixel actuators...
