Learn Robotics Programming

By: Danny Staple

Overview of this book

We live in an age where the most difficult human tasks are now automated. Smart and intelligent robots, which will perform different tasks precisely and efficiently, are the requirement of the hour. A combination of Raspberry Pi and Python works perfectly when making these kinds of robots. Learn Robotics Programming starts by introducing you to the basic structure of a robot, along with how to plan, build, and program it. As you make your way through the book, you will gradually progress to adding different outputs and sensors, learning new building skills, and writing code for interesting behaviors with sensors. You’ll also be able to update your robot, and set up web, phone, and Wi-Fi connectivity in order to control it. By the end of the book, you will have built a clever robot that can perform basic artificial intelligence (AI) operations.

The following are further practical robotics books available that I enjoy:

123 Robotics Experiments for the Evil Genius by Myke Predko: This is perhaps a little dated, but spends time on the construction and workshop techniques along with building electronics circuits. It doesn't really dig into code.
Robot Programming: A Guide to Controlling Autonomous Robots by Tracey Hughes and Cameron Hughes: A code-based investigation into robotic programming techniques, based on the Java programming language. A colorful and well-illustrated book. You will find the robot built in this book fits the criteria to start programming in that book pretty well, with only a gripper needed to complete it.
Robot Building for Beginners by David Cook: This book leads you through building "sandwich", a scratch-built robot based on a lunchbox. It is a little more maker-...
