• Ultrasonic sensors: These are short-range sensors used for parking and low-speed maneuvers.

Then there is the brain of the operation: The software. This is where all the processing happens. The software analyzes the data from the sensors, identifies objects, makes decisions, and controls the vehicle's movements. This involves:

• Perception: Interpreting the data from the sensors to understand the environment.
• Localization: Determining the car's precise position on the map.
• Mapping: Creating and updating detailed maps of the environment.
• Path planning: Deciding the best route to the destination.
• Control: Controlling the steering, acceleration, and braking.

The system needs to constantly update its understanding of the surrounding environment to ensure smooth and safe navigation. Each component plays an essential role in ensuring the vehicle's safe and efficient operation. This includes everything from the smallest detail, such as the type of tire used, to the complex algorithms that process the data from the sensors. It's a marvel of modern engineering, and it’s only getting better!

Finally, we've got the hardware. This includes powerful computers and processors that can handle the massive amounts of data generated by the sensors. Also, the control systems that manage the car's functions, like steering, braking, and acceleration. These are the workhorses that make everything happen. The efficiency and reliability of these components are paramount to the overall performance of the self-driving car. They need to be incredibly fast, incredibly accurate, and able to withstand a wide range of operating conditions. The combination of all these elements allows the car to make decisions, react to the environment, and navigate through the world autonomously.
