ROS Robotics Projects

Overview of this book

Robot Operating System is one of the most widely used software frameworks for robotic research and for companies to model, simulate, and prototype robots. Applying your knowledge of ROS to actual robotics is much more difficult than people realize, but this title will give you what you need to create your own robotics in no time! This book is packed with over 14 ROS robotics projects that can be prototyped without requiring a lot of hardware. The book starts with an introduction of ROS and its installation procedure. After discussing the basics, you’ll be taken 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 ROS robotics applications for beginner, intermediate, and expert levels inside! This book will be the perfect companion for a robotics enthusiast who really wants to do something big in the field.

Preface

Setting Robotics Toolbox in MATLAB


Here is the link to download a trial or purchase the Robotics Toolbox in MATLAB (https://in.mathworks.com/products/robotics.html). This toolbox is compatible with MATLAB version 2013 onward. If you don't have MATLAB, you can test the chapter's code using a trial version; if you have it, buy or download a trial version of Robotic Toolbox.

Basic ROS functions in MATLAB

After setting up Robotics Toolbox in MATLAB, we can start working on the important functions of MATLAB that are used to interact with a ROS network. Let's look at them with examples.

Initializing a ROS network

Before running a ROS node, we have to run the roscore command, right? The roscore command will start a ROS master, and other ROS nodes can find each other through it. In MATLAB, instead of the roscore command, we can use the rosinit function to start a ROS master.

The rosinit function can start a ROS master and a global node that is connected to the...
