Overview of this book

This Learning Path takes you on a journey in the world of robotics and teaches you all that you can achieve with Raspberry Pi and Python. It teaches you to harness the power of Python with the Raspberry Pi 3 and the Raspberry Pi zero to build superlative automation systems that can transform your business. You will learn to create text classifiers, predict sentiment in words, and develop applications with the Tkinter library. Things will get more interesting when you build a human face detection and recognition system and a home automation system in Python, where different appliances are controlled using the Raspberry Pi. With such diverse robotics projects, you'll grasp the basics of robotics and its functions, and understand the integration of robotics with the IoT environment. By the end of this Learning Path, you will have covered everything from configuring a robotic controller, to creating a self-driven robotic vehicle using Python. • Raspberry Pi 3 Cookbook for Python Programmers - Third Edition by Tim Cox, Dr. Steven Lawrence Fernandes • Python Programming with Raspberry Pi by Sai Yamanoor, Srihari Yamanoor • Python Robotics Projects by Prof. Diwakar Vaish

Making the robot safe


In the previous part of the chapter, with our multiple attempts, we have been able to find the maximum positions for each of the servos. Now it's time to use these values. In this chapter, we will be programming the servos for what its absolute maximums are. In this program, we will make sure that servos will never need to travel even a degree beyond the defined parameters on both the sides. If the user gives a value beyond it, then it will simply choose to ignore the user inputs instead of causing self damage.

So, let's see how to get it done. There are some parts of this program, where the numeric values have been bold. These are the values that you need to replace with the values which we have noted in the previous section of this chapter. For example, for servo 1, the values noted down are 23 and 170 as the maximum values for either side. Hence, the change in the code will be from if a[0] < 160 and a[0] > 30 to ifa[0] < 170 and a[0] > 23. Similarly, for...
