In this chapter, you have learned how to build a wirelessly-controlled robot with the Zumo chassis kit. The quick learning curve presented how to assemble the Zumo chassis kit with the Raspberry Pi 3 and a motor driver to drive two gear motors and form the engine. Also, you connected to the robot using the PuTTY terminal installed on your computer with SSH. The built-in Wi-Fi module of the Raspberry Pi 3 allowed you to connect wirelessly from your computer, and then you execute the jar file located in the SD card of the Pi through SSH, using the keyboard.
You can connect an external Wi-Fi antenna to the Raspberry Pi 3 to achieve long-range connectivity with your Wi-Fi network, but it will violate FCC regulations.
The Chapter 6, Building a Multipurpose IoT Controller, shows how to build a multipurpose IoT controller with simple web services and a SQLite database. This project allows you to gather and store...
