Motion Planning is a field in robotics and computer science that focuses on determining a sequence of movements for a robot or object to reach a specific goal while avoiding obstacles. It involves algorithms that calculate the best path in a given environment, ensuring that the movements are efficient and safe. This process is crucial for various applications, including autonomous vehicles, robotic arms, and drones. By using techniques such as graph theory and probabilistic methods, motion planning helps machines navigate complex spaces, making them more effective in performing tasks in real-world scenarios.
