Robotics has become the buzz word of today's fast paced growing digital world. Robots are being used in every industry, be it in space, manufacturing, auto, or even in the medical industry. In the previous chapters, you learned about web servers, basics of electronics, and how to connect Raspberry Pi to the real world using the GPIO port. This chapter ties together everything that you have learned so far. Also, a few more electronics components will be introduced that are required to build your own robot. Once you have understood the electronic components, you will learn how to develop a remote-controlled robot that displays a real-time video feed from the Raspberry Pi camera and display the distance to a nearest object using an ultrasonic sensor. We will cover the following sections in this chapter:
