Mastering ROS for Robotics Programming

By: Lentin Joseph

Overview of this book

The area of robotics is gaining huge momentum among corporate people, researchers, hobbyists, and students. The major challenge in robotics is its controlling software. The Robot Operating System (ROS) is a modular software platform to develop generic robotic applications. This book discusses the advanced concepts in robotics and how to program using ROS. It starts with 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. After discussing robot manipulation and navigation in robots, you will get to grips with the interfacing I/O boards, sensors, and actuators of ROS. One of the essential ingredients of robots are vision sensors, and an entire chapter is dedicated to the vision sensor, its interfacing in ROS, and its programming. You will discuss the hardware interfacing and simulation of complex robot to ROS and ROS Industrial (Package used for interfacing industrial robots). Finally, you will get to know the best practices to follow when programming using ROS.

Interfacing Intel Real Sense camera with ROS


One of the new 3D depth sensors from Intel is Real Sense. The following link is the ROS interface of Intel Real Sense: https://github.com/BlazingForests/realsense_camera

Figure 11: Intel Real Sense

Before installing the ROS driver, we have to install the following packages for building the source code:

$ sudo apt-get install libudev-dev libv4l-dev

After installing, clone the ROS package to the src folder of catkin workspace:

$ cd ~/catkin_ws/src
$ git clone https://github.com/BlazingForests/realsense_camera.git
$ catkin_make

Launch the Real Sense camera driver and RViz using the following command:

$ roslaunch realsense_camera realsense_rviz.launch

Launch Real Sense camera driver only:

$ roslaunch realsense_camera realsense_camera.launch

Following are the topics generated by the Real Sense driver:
