Anyone else immediately think of those floating orbs from half-life 2? I'm imagining the U.S. military will be developing something similar if it hasn't already - the use cases just seem too extensive. I mean, something like that could float along in front of a unit/convoy deployed in hostile areas and scan/sense for IEDs, or you could have a distributed swarm of these patrolling streets at night with IR cameras, reporting any trouble. They'd be able to see under canopies, inside alleyways, even enter enclosures and buildings (physically if not legally). The fact that it's blades are some-what enclosed also makes it safer for close quarters operations without getting thwacked or cut up by a helicopter blade as well. Another orwellian thought with a mixture of huxley - what if the future doesn't begin with these types of surveillance tech imposed on us by our government, patrolling our streets with cameras and other sensors, but rather with a slick company manufacturing and marketing it as a guardian-angel device? Afraid of a family member being unsupervised? Call in the UAV to keep tabs on them from your smartphone. Want to go for a jog, but it's getting dark out? Bring along the Orb with flash-light, GPS, ability to call for help, etc. If you think it would be too ridiculous to happen, and that people wouldn't want to look ridiculous to these things hovering over them at all times, just wait until they get smaller...
