Autonomous vehicles

Definition

Autonomous vehicles, also known as self-driving cars, are vehicles equipped with technology that allows them to navigate and operate without human intervention. They utilize a combination of sensors, cameras, artificial intelligence, and machine learning to perceive their environment, make decisions, and safely transport passengers or goods. The effectiveness of autonomous vehicles heavily relies on sensor fusion techniques for precise localization and obstacle detection.

5 Must Know Facts For Your Next Test
