We covered a lot in this chapter! Let's recap what we learned.
The focus of this project was to demonstrate how smart robots use infrared technology. Infrared is invisible to humans but can be detected by a robot's sensors, so it is a great option for when you want to invisibly control a robot. The tank robot uses two EV3 IR sensors to measure the position of an infrared beacon and follow it.
We also learned about some mechanical design concepts, that are applied to smart robots: tank treads and tank steering, turntables and cams, and using a motor to perform more than one function at a time. We briefly discussed gear ratios as they function in the tank; this is something we will explore further in the next chapter. We also discussed ...
