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

Working with the ROS-VR application and interfacing with Gazebo


The new APK will be installed with a name such as ROSSerial; before starting this app, we need to set a few things up on the ROS PC.

The next step is to set the ROS_IP variable in the .bashrc file. Execute the ifconfig command and retrieve the Wi-Fi IP address of the PC, as shown here:

Figure 13: PC Wi-Fi adapter IP address

For this project, the IP address was 192.168.1.101, so we have to set the ROS_IP variable as the current IP in .bashrc. You can simply copy the following line to the .bashrc file:

$ export ROS_IP=192.168.1.101

We need to set this; only then will the Android VR app work.

Now start the roscore command on the ROS PC:

$ roscore

The next step is to open the Android app, and you will get a window like the following. Enter ROS_IP in the edit box and click on the CONNECT button.

If the app is connected to the ROS master on the PC, it will show up as connected and show a blank screen with...
