Mastering ROS for Robotics Programming, Third edition - Third Edition

By: Lentin Joseph, Jonathan Cacace

Overview of this book

The Robot Operating System (ROS) is a software framework used for programming complex robots. ROS enables you to develop software for building complex robots without writing code from scratch, saving valuable development time. Mastering ROS for Robotics Programming provides complete coverage of the advanced concepts using easy-to-understand, practical examples and step-by-step explanations of essential concepts that you can apply to your ROS robotics projects. The book begins by helping you get to grips with the basic concepts necessary for programming robots with ROS. You'll then discover how to develop a robot simulation, as well as an actual robot, and understand how to apply high-level capabilities such as navigation and manipulation from scratch. As you advance, you'll learn how to create ROS controllers and plugins and explore ROS's industrial applications and how it interacts with aerial robots. Finally, you'll discover best practices and methods for working with ROS efficiently. By the end of this ROS book, you'll have learned how to create various applications in ROS and build your first ROS robot.

Understanding DYNAMIXEL ROS servo controllers for robot hardware interfacing

Till now, we have learned about MoveIt! interfacing using Gazebo simulation. In this section, we will see how to replace Gazebo and put a real robot interface to MoveIt!. Let's discuss DYNAMIXEL servos and the ROS controllers.

DYNAMIXEL servos

DYNAMIXEL servos are smart, high-performance networked actuators for high-end robotics applications. These servos are manufactured by a Korean company called ROBOTIS (http://en.robotis.com/). These servos are very popular among robotics enthusiasts because they can provide excellent position and torque control, as well as a variety of feedback, such as position, speed, temperature, voltage, and so on. One of their useful features is that they can be networked in a daisy-chain manner. This feature is very useful in multi-joint systems, such as robotic arms, humanoid robots, robotic snakes, and others. The servos can be directly connected to PCs using a Universal...
