You must be thinking: what can we possibly learn about the vehicle that we don't already know? This may be true, but there are a few that we must make sure we understand before taking on this chapter. So, let's get started.
First is the chassis, which we will be using: it's is a four-wheel drive chassis and all the four wheels are independently controlled by a dedicated motor. Hence, we can change the speed of every single wheels as per our needs. We have chosen a four-wheel drive drivetrain as it is harder for it to get stuck on carpets and uneven surfaces. You can also opt for a two-wheel drive drivetrain if you want to do so, as it won't make a huge difference.
Now, once you assemble the chassis you might see that it does not have a steering mechanism. Does this mean that the car will only go straight? Well, obviously not. There are many ways by which we can steer the direction of a car while making small vehicles. The best one is called differential turning.
