_ Click to launch the photo gallery_ Grand Challenges are ambitious but achievable, imagination-inspiring but believable, and they have to have results that are measurable–like sequencing the human genome, or landing a couple of people on the moon and returning them safely home. Past DARPA Grand Challenges have led to self-driving cars, translating messages on shredded paper, and more–soon, even humanoid robots that can work alongside human warfighters. DARPA wants some help picking a new one, and there’s a formal request for proposals. So we went ahead and made some of our own. Visit the gallery to see them and add yours in the comments.
