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.

Chapter 7, Drive and Turn - Moving Motors with Python

  • Why do we use the atexit.register mechanism?
    • To register a stop function, so the robot's motors will stop when the code stops, even if there is an error
  • How can we correct a motor going the wrong way?
    • We can swap the two motor-lead connections for that motor at the screw terminals.
  • What are the main advantages of a common interface for a Robot object?
    • We can build new behaviors on top of the object without writing setup and translation code repeatedly.
    • We can move our behaviors onto other motor controllers by wrapping them in the same interface.
  • How must the motors move (left and right) to make this robot turn?
    • To turn, one motor must be going at a different speed from the other.
    • To spin, one motor should be going in the opposite direction from the other.
