You may like to listen to Talking Robots podcasts. Those are interviews with well-known researchers (such as Rodney Brooks, Marco Dorigo, Dario Floreano, Owen Holland, Francesco Mondada, Ron Pfeifer, and Luc Steels whom I more or less know) working on robotics on fascinating topics like Evolution of Communication, Human-Robot Teams, Robot Consciousness, Swarm Robotics, Robot Cognition, Behavior-based Robotics, Evolutionary Robotics, Embodied Cognition, and etc.
Enjoy the show!
