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.

Questions

  1. We used the HSV color system when tracking colored objects. Why would the RGB color system not work for this?
  2. PID controllers (or PI control) were used for both behaviors. To the color-tracking behavior, we added an anti-windup measure—what would happen without this limit?
  3. When performing computer vision, we use a low resolution for the images. What are some of the reasons for choosing a low resolution?
  4. Why do we use queues to send data between the processes in our system?
  5. In the color-tracking behavior, what step is needed in between using color filters to make a masked image, and generating enclosing circles for the remaining blobs?

For further learning, I recommend the reader try the other cascade files found in the /usr/share/opencv/haarcascades folder on the Raspberry Pi. Perhaps you could try swapping features of the two behaviors, in order to use the...
