Overview of this book

The Raspberry Pi is a series of credit card-sized single-board computers developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools. The Raspberry Pi is known as a tiny computer built on a single circuit board. It runs a Linux operating system, and has connection ports for various peripherals so that it can be hooked up to sensors, motors, cameras, and more. Raspberry Pi has been hugely popular among hardware hobbyists for various projects, including robotics. This book gives you an insight into implementing several creative projects using the peripherals provided by Raspberry Pi. To start, we’ll walk through the basic robotics concepts that the world of Raspberry Pi offers us, implementing wireless communication to control your robot from a distance. Next, we demonstrate how to build a sensible and a visionary robot, maximizing the use of sensors and step controllers. After that, we focus on building a wheeled robot that can draw and play hockey. To finish with a bang, we’ll build an autonomous hexcopter, that is, a flying robot controlled by Raspberry Pi. By the end of this book, you will be a maestro in applying an array of different technologies to create almost any imaginable robot.

Chapter 5. A Robot That Can Draw

You've modified several toys, built a wheeled and tracked platform, and made them all do amazing things. In this chapter, you'll move from a mobile platform to a fixed one, with a specific goal in mind; to build a robot that can draw.

In this chapter, you'll learn:

  • Constructing a drawing platform using servos and brackets

  • Using a servo controller to control multiple servos

  • Creating a Python program to control servos

  • Using servos to create a drawing robot

  • Connecting to a graphical Python program to control the movement of the drawing robot
