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.

Questions

  1. Is it mandatory for a robot to have a computer such as Raspberry Pi?

A) Yes, because the computer powers the controller board.
B) No, because the computer is only needed for visualizing the software code on a screen. It may work alone with the controller if a program has been flashed to it.
C) Not really; you could write a small program that controls the robot and flash it to the chip of the controller. Every time you power the robot, it will execute the program in an endless loop.

  1. What kind of radiation is emitted by the distance sensor of GoPiGo3?

A) Laser
B) Infrared
C) Ultrasound

  1. Why can't you see the light being emitted by the line-follower sensor?

A) Because the sensor has to be previously activated with a software command
B) It does not emit light but a magnetic field
C) It does not emit anything in the visible range of light
