Hands-On ROS for Robotics Programming

By: Bernardo Ronquillo Japón

Overview of this book

Connecting a physical robot to a robot simulation using the Robot Operating System (ROS) infrastructure is one of the most common challenges faced by ROS engineers. With this book, you'll learn how to simulate a robot in a virtual environment and achieve desired behavior in equivalent real-world scenarios. This book starts with an introduction to GoPiGo3 and the sensors and actuators with which it is equipped. You'll then work with GoPiGo3's digital twin by creating a 3D model from scratch and running a simulation in ROS using Gazebo. Next, the book will show you how to use GoPiGo3 to build and run an autonomous mobile robot that is aware of its surroundings. Finally, you'll find out how a robot can learn tasks that have not been programmed in the code but are acquired by observing its environment. You'll even cover topics such as deep learning and reinforcement learning. By the end of this robot programming book, you'll be well-versed with the basics of building specific-purpose applications in robotics and developing highly intelligent autonomous robots from scratch.

A methodology to programmatically apply ML in robotics

A specific aspect of ML is that robot responses have to happen in real time, without delays, so that the actions taken are effective. For example, if it finds an obstacle crossing the path it is following, we expect that it avoids it. To do so, obstacle identification has to occur as it appears in the robot's field of view. Hence, the subsequent action of avoiding the obstacle has to be taken immediately to avoid a crash.

We will support our methodology description with an end-to-end example that covers all that GoPiGo3 can do up to this point. Then, with this example, we expect that GoPiGo3 can carry a load on top of its chassis from its current location to a target location (a common case in garbage collector robots).
