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 10, Using Python to Control Servo Motors

  • What does the acronym PWM stand for?
    • Pulse Width Modulation: the means of controlling a device by varying the size (or width in time) of pulses sent to the device
  • In terms of the Servo motor's internal mechanism, from what components is the error calculated?
    • The difference between the actual current position of the motor and the requested position of the motor
  • What is a servo "horn"?
    • A small collar with arms to attach to a servo motor spindle to convert its output into motion
  • What could result from a servo being impeded when trying to reach a requested position?
    • It can lead to overheating and damage to the servo motor.
