Learn Robotics Programming

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.

Making a robot display code object

As discussed previously, although we are building around an APA102C-based stick, there is more than one type of RGB LED system. We could choose something with any number of implementations. The best way to deal with this, as we saw in the chapter on motors, is to abstract it that is, to put the code into an object with an interface we've designed so that the small differences in interfaces between real hardware and their libraries is hidden from the behaviors.

So, what interface would we want for the LEDs? First, we'd want them to be available on the robot as methods in robot.leds. We will want to clear the LEDs (turn them all off), set an individual LED to an individual color, or set a bunch/range of LEDs to a list of colors.

We also want the robot code to tell us how many LEDs we have, so if the number changes, some of the animations...
