It is time to tackle our first project! In this chapter, we will build and program a small EV3 tank that uses infrared sensors to track and target a beacon. You can think of it as a miniature model tank that you can use to keep your room safe from intruders!
The tank demonstrates how smart robots in the real world use infrared technology. We briefly mentioned this technology in the first chapter. Infrared refers to a wavelength of light that is invisible to the human eye. However, robots can incorporate sensors that can detect infrared light. This makes infrared a convenient way to invisibly send messages to a robot or allow a robot to see something that a human cannot see.
The EV3 remote control can ...
