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.

Summary

Creating basic applications using the ROS-Android interface

We have covered Android - ROS applications provided from the ROS repository. So how can we create our own application using it? Let's take a look.

First, we have to create a separate workspace for our application. Here, it is named myandroid:

$ mkdir -p ~/myandroid/src

Switch to the workspace's src folder:

$ cd ~/myandroid/src

Create a package called android_foo that depends on android_core, rosjava_core, and std_msg:

$ catkin_create_android_pkg android_foo android_core rosjava_core std_msgs

Switch into android_foo and add sample libraries to check whether the project is building properly:

$ cd android_foo
$ catkin_create_android_project -t 10 -p com.github.ros_java.android_foo.bar bar
$ catkin_create_android_library_project -t 13 -p com.github.ros_java.android_foo.barlib barlib
$ cd ../..

And finally, you can build the empty project using catkin_make:

$ catkin_make

If it is building properly, you can add a custom project,...
