Introduction

In the previous lesson we've learned that the wheels of the car are rotating with different speed when the vehicle is making a turn and that is the reason they cannot be connected to the same motor. But what if we connect only one of the rear wheels with the motor and we leave the other one free?

Today we're experimenting with a truck that is designed to transport cargo through rough terrain. The focus here again is on the construction. Hopefully, you've learned to park in the previous lesson, because you may need it again!
