Have I mentioned the Robots Podcast here yet? Oh, probably, but it really does bear repetition.
Between the Robots Podcast and its predecessor, Talking Robots (scroll down), well over a hundred episodes have been archived, each of which features at least one interview with someone deeply involved in robotics or and/or a related field (animal behavior, for instance), with occasionaldetours into cultural responses to the advent of adaptive machines. Actively listening to the entire collection must be equivalent to a graduate level survey course in robotics.
Each episode has its own web page, and the links on those pages, taken together, read like a compendium of top-flight robotics programs and companies, if not comprehensive then a very good start on being so. It's a great way to get a quick overview of who is doing what, where.
