Darpa's Next Challenge? A Grueling Underground Journey

I can't sit here and guarantee you a robot won't take your job one day--capitalism kind of has a thing for automation. What I can tell you is that in the near future, robots will be doing jobs that no one wants to do. Which is why for its next robotics competition, Darpa is going underground, with the Darpa Subterranean Challenge. If you don't remember, that's the same far-out federal research agency that put on the Grand Challenge (which helped kick off the self-driving car revolution), and the Robotics Challenge (which helped get humanoids walking among us). And now it's calling on researchers to autonomously explore the innards of Earth.
