Jud Kauffman and Joe Wolfel, co-founders of Austin, Texas-based startup Terradepth, are building autonomous submarines for deep ocean exploration. Its long-term goal is to build the Google Earth of the ocean. They discuss the challenges and opportunities of Terradepth's mission and how their Naval experience is playing a vital role.

We also chat with Nader Elm, CEO and co-founder of Exyn Technologies. Exyn is a spin-off of the GRASP Laboratory at the University of Pennsylvania that builds autonomous drones that are operating in GPS-denied environments such as mines.
