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.

Motion planning of robot in RViz using MoveIt! configuration package


MoveIt! provides a plugin for RViz, which allows it to create new planning scenes where robot works, generate motion plans, and add new objects, visualize the planning output and can directly interact with the visualized robot.

The MoveIt! configuration package consists of configuration files and launch files to start motion planning in RViz. There is a demo launch file in the package to explore all the functionalities of this package.

The following is the command to invoke the demo launch file:

$ roslaunch seven_dof_arm_config demo.launch

If everything works fine, we will get the following screen of RViz being loaded with the MotionPlanning plugin provided by MoveIt!:

Using the RViz Motion Planning plugin

From the preceding figure , we can see that the RViz-Motion Planning plugin is loaded on the left side of the screen. There are several tabs on the Motion Planning window, such as Context, Planning...
