EPISODE DESCRIPTION
Anca Dragan is a professor at Berkeley, working on human-robot interaction -- algorithms that look beyond the robot's function in isolation, and generate robot behavior that accounts for interaction and coordination with human beings.

EPISODE SUMMARY
In this episode of Lex Fridman Podcast, featuring Lex Fridman and Anca Dragan, Anca Dragan: Human-Robot Interaction and Reward Engineering | Lex Fridman Podcast #81 explores Designing Robots That Understand Human Intent, Limits, and Preferences Lex Fridman and Anca Dragan discuss human-robot interaction with a focus on how robots can model, predict, and adapt to human behavior and preferences. They explore inverse reinforcement learning, rationality assumptions, and how to reinterpret human 'irrationality' as optimal behavior under different beliefs, constraints, or physics models. A major theme is reward design: how hard it is to specify objectives that elicit the right behavior in all situations, and how robots can learn from 'leaked' information in human actions, corrections, environment, and even emergency stops. They also touch on autonomous driving, semi-autonomous systems, ethical and social dimensions of robots, and broader reflections on meaning, mortality, and what it means to build AI that truly serves humans.
