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 it start when the Pi starts

You now have a menu system to launch your robot behaviors, and a set of compatible behaviors in it. Although using ssh to log in is great to debug, see problems, and fix them, if you want to demonstrate your robot, it is even better to turn on your robot, point your phone browser at it once the lights stop blinking, and go.

We are going to do two things to make this useful:

  • Use an LED to indicate that it's ready (in menu mode) to allow the robot to tell us before our phone has linked to the page
  • Use systemd to automatically start the menu Flask server when the robot is switched on

Adding lights to the menu server

We won't want the whole robot system added to our menu, but the...
