ROS Programming: Building Powerful Robots

By: Anil Mahtani, Aaron Martinez, Enrique Fernandez Perdomo, Luis Sánchez, Lentin Joseph

Overview of this book

This learning path is designed to help you program and build your robots using open source ROS libraries and tools. We start with the installation and basic concepts, then continue with the more complex modules available in ROS, such as sensor and actuator integration (drivers), navigation and mapping (so you can create an autonomous mobile robot), manipulation, computer vision, perception in 3D with PCL, and more. We then discuss advanced concepts in robotics and how to program using ROS. You'll get a 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. We'll go 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 beginner, intermediate, and expert ROS robotics applications inside! It includes content from the following Packt products: ? Effective Robotics Programming with ROS - Third Edition ? Mastering ROS for Robotics Programming ? ROS Robotics Projects

Playing with ROS-Android applications


In this section, we will see how to install the ROS-Android application generated from the preceding build process on your Android phone.

Let's take the android_core folder and search for .apk files; you may get a bunch of applications, as shown in the following figure:

Figure 25: List of generated APK files

You can copy the APK files and install them on your phone.

Troubleshooting

You may get errors while installing these APK files. One of the errors is shown in the following screenshot:

Figure 26: Parse error during installation of APK

Here are the tips to solve this issue:

The first step is to enable installation from Unknown sources, as shown in section 1 of the following figure:
