Path planning is the process of determining a route for a moving object, such as a robot or vehicle, to follow from a starting point to a destination. This involves analyzing the environment to identify obstacles and selecting the most efficient path while considering factors like distance, safety, and time. In robotics, path planning algorithms, such as A* or Dijkstra's algorithm, are commonly used to compute the best route. These algorithms help ensure that the moving object can navigate through complex spaces, making them essential for applications in areas like autonomous vehicles and drone navigation.
