What are the key algorithms used in pathfinding for robotics?
Some key algorithms include A*, Dijkstra's, and Rapidly-exploring Random Trees (RRT). Each has its strengths.
Can you explain how the A* algorithm works?
Sure! A* uses a heuristic to estimate the cost from the current node to the goal, combining it with the cost to reach the current node.
What are the advantages of using Dijkstra's algorithm?
Dijkstra's algorithm guarantees the shortest path in a weighted graph and is effective for graphs without negative weights.
How does RRT differ from A*?
RRT is more suited for high-dimensional spaces and can quickly explore large areas, while A* is more precise in known environments.
What applications use these pathfinding algorithms?
They are used in robotics for navigation, autonomous vehicles, and even in video games for character movement.
