Just imagine a car driving itself without the help of anyone. Self-driving cars are like robot cars that can think and decide which path to navigate to reach their destination. You only need to specify the destination, and a robot car will take you there safely. To convert an ordinary car into a robotic car, we should add some robotic sensors to it. We know that, for a robot, there should be at least three important capabilities. It should be able to sense, plan, and act. Self-driving cars satisfy all of these requirements. We'll discuss all of the components we need to build a self-driving car. Before discussing the building of a self-driving car, let's go through some milestones in self-driving car development.
