🤖 AI for Path Planning
📘 Definition
Path Planning in AI refers to the computational process of determining an optimal route or path from a start point to a target destination, often while avoiding obstacles and minimizing cost such as distance, time, or energy.
🔍 Detailed Description
Path planning is a fundamental component in robotics, autonomous vehicles, and AI navigation systems. It involves algorithms that calculate a sequence of valid configurations or movements to move an agent from its initial position to a goal while considering environmental constraints.
The algorithms used for path planning can be classical search methods like A*, Dijkstra’s algorithm, or sampling-based techniques such as Rapidly-exploring Random Trees (RRT) and Probabilistic Roadmaps (PRM). AI-enhanced path planning incorporates machine learning to improve decision-making in complex, dynamic environments.
Effective path planning ensures safety, efficiency, and real-time adaptability, which is crucial for applications like drones, robotic arms, warehouse automation, and autonomous cars. It balances trade-offs among shortest path, obstacle avoidance, and computational resources.
