Learning Robotics with Python contains twelve chapters that mainly aims at how to build an autonomous mobile robot from scratch and how to program it using Python. The robot mentioned in this book is a service robot, which can be used to serve food at home, hotels, and restaurants. From the beginning to end, this book discusses the step-by-step procedure on how to build this robot. The book starts with the basic concepts of robotics and then moves on to the 3D modeling and simulation of the robot. After the successful simulation of the robot, it discusses the hardware components required to build the robot prototype in order to complete the robot navigation.
The software part of this robot is mainly implemented using the Python programming language and software frameworks, such as Robot Operating System (ROS), Open-CV, and so on. You will understand the application of Python from the aspects of designing the robot to the robot’s user interface. The Gazebo simulator is used to simulate the robot and machine vision libraries, such as Open-CV and OpenNI. PCL is used to process the 2D and 3D image data of the robot. Each chapter is presented with an adequate theory to understand the application aspect. The book is reviewed by experts in this field who are passionate about robotics.
Chapter 1, Introduction to Robotics, contains basic concepts and terminologies of robotics. This chapter is a must for beginners who are just starting with robotics.
Chapter 2, Mechanical Design of a Service Robot, discusses the 2D and 3D CAD designing aspect of the robot using LibreCAD and Blender (free software). This chapter also demonstrates how to use Blender Python APIs in order to build the 3D model.
Chapter 3, Working with Robot Simulation Using ROS and Gazebo, takes you through the simulation of the service robot using Gazebo and ROS.
Chapter 4, Designing ChefBot Hardware, explains the hardware designing of the robot, including block diagram and hardware components required to build ChefBot.
Chapter 5, Working with Robotic Actuators and Wheel Encoders, covers interfacing of robotic actuators and wheel encoders using Tiva C LaunchPad. It also mentions high-end smart actuators like dynamixel.
Chapter 6, Working with Robotic Sensors, discusses interfacing of ultrasonic distance sensors, IR proximity sensors, and IMU using Tiva C LaunchPad.
Chapter 7, Programming Vision Sensors Using Python and ROS, talks about the introduction to Open-CV, OpenNI, and PCL libraries and interfacing these to ROS and programming using Python.
Chapter 8, Working with Speech Recognition and Synthesis Using Python and ROS, discusses speech recognition and synthesis using various libraries and interfacing it to ROS programming using Python.
Chapter 9, Applying Artificial Intelligence to ChefBot Using Python, covers tutorials to build a ChatterBot. This can be used to make the robot interactive.
Chapter 10, Integration of ChefBot Hardware and Interfacing it into ROS, Using Python, explores tutorials to integrate the complete hardware and essential software section. It mainly discusses autonomous navigation of the service robot and how to program it using ROS and Python.
Chapter 11, Designing a GUI for a Robot Using Qt and Python, covers tutorials on how to build a GUI for the user who operates the robot in a typical restaurant. The GUI is built using Qt and the PyQt Python wrapper.
Chapter 12, The Calibration and Testing of ChefBot, explores tutorials on how to calibrate and test the robot for the final run.
