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.

Chapter 13, Robot Vision - Using a Pi Camera and OpenCV

  • We used the HSV color system when tracking colored objects. Why would the RGB color system not work for this?
    • When tracking color, the ranges used to filter are looking for a range of hues; for example, greens or reds. Tracking this in relation to the green and blue elements on RGB colors is tricky and perhaps not really viable.
  • PID controllers (or PI control) were used for both behaviors. On the color track behavior we added an anti-windup measure, what would happen without this limit?
    • The integral sum would grow too high, which can cause the robot to overshoot if the response takes time.
  • When performing computer vision, we use a low resolution for the images. What are some of the reasons for choosing a low resolution?
    • Less data to move around the system keeps the web app responsive
    • Faster processing times for the...
