🤖Robots rely on planning algorithms to make decisions in uncertain environments.
🗺️Shortest path algorithms are often used as a starting point for planning under uncertainty.
🚗Probabilistic models are used to represent different outcomes of actions, such as traffic levels.
🌧️Uncertainty in the world can affect the outcome of robot decisions, such as weather conditions.
⏰Markov decision processes are commonly used to model decision-making in uncertain environments.
What is a Markov decision process?
—A Markov decision process is a model used to describe decision-making in uncertain environments, where the outcome of an action depends on the current state.
How do robots make decisions in uncertain environments?
—Robots use planning algorithms and probabilistic models to evaluate different actions and their potential outcomes in order to make informed decisions.
What role do shortest path algorithms play in planning under uncertainty?
—Shortest path algorithms are often used as a starting point for planning under uncertainty, providing a baseline for evaluating different paths and actions.
How does uncertainty affect robot decision-making?
—Uncertainty, such as varying traffic levels or weather conditions, can affect the outcome of robot decisions and require adaptive planning strategies.
What are some challenges in planning under uncertainty?
—Challenges in planning under uncertainty include determining accurate probabilistic models, handling complex decision spaces, and adapting to dynamic environments.
