Some interesting thinking in this week's Robots Podcast
, on the past 50 years and next 50 years of robotics. One of those interviewed is Jean-Christophe Zufferey
, who focuses on UAVs. Along with discussing the past two decades' advances in UAVs very well, he speculates on what's next, including the idea of "personal UAVs", like flying assistant droids, which could give you an aerial view of your surroundings or do communications relay.
He also discusses the possibility of "3D elevators" or transportation UAVs, that would allow commuter aircraft without the danger and complexity of having to drive. You'd just get in, give it a destination, and get out when you got there.
