Autonomous navigation is a research area that focuses on developing systems and algorithms that allow vehicles or robots to navigate without human intervention. These systems use various sensors, such as GPS, lidar, and cameras, to perceive their surroundings and make decisions about how to move through their environment. Autonomous navigation is a key component of autonomous vehicles, drones, and robots, and has applications in fields such as transportation, defense, and logistics. Researchers in this area are working to improve the accuracy, reliability, and efficiency of autonomous navigation systems to enable safe and effective autonomous operation.
