In this chapter, we took our project in a completely new direction and broke away from tank-style driving to make a purpose-built speed machine. While building the Falcon, we learned about some of the mechanical components used to make a car-style drivetrain, such as the differential. We reapplied the rack-and-pinion mechanism to use it for steering. We discussed how each of the mechanical features in the Falcon relates to the design of cars in the real world.

We extensively used the rotation sensor built into the EV3 motors to coordinate an intelligent steering system. We also learned how to make MyBlocks and saw the advantages they bring when they are used in a program. We applied knowledge acquired in previous chapters to make a car-style remote control program. Finally, we resolved the paradox of a smart remote control car: even though the user controls the Falcon, its programming automatically coordinates a lot of complex decisions and actions behind the scenes.

In the next chapter, we will ditch the remote control altogether and program the Falcon to use a GPS receiver and a compass to navigate autonomously.
