The US Department of Defense is launching a research effort to develop underwater robots/sensor platforms that would hibernate on the ocean floor until they "wake up when commanded, and deploy to surface providing operational support and situational awareness." DARPA has dubbed the research effort the Upward Falling Payloads program. (The image below, from the DARPA press release, seems to be illustrating, um, a robot's-eye-view as it's surfacing.) From their announcement:
Depending on the specific payload, systems would provide a range of non-lethal but useful capabilities such as situational awareness, disruption, deception, networking, rescue, or any other mission that benefits from being pre-distributed and hidden. An example class of systems might be small unmanned aerial vehicles (UAVs) that launch to the surface in capsules, take off and provide aerial situational awareness, networking or decoy functions. Waterborne applications are sought as well.

You may not love Microsoft Word, but you’ve definitely used it. Other than being one of the most ubiquitous programs on the planet, it’s been the go-to word processing system for more than a quarter-century because it’s as basic as it gets. But occasionally, you’ve got assignments that beg for a lot more options than simple […]
Almost everyone has their smartphone in a case of one kind or another. Beyond simple protection, finding a case that can charge your phone on its own, but doesn’t feel like it’s also adding a couple pounds to the phone’s weight is the tricky part. Billed as the world’s thinnest battery case, the ThinCharge iPhone […]
You never know when new projects, ideas or opportunities can drop into your lap at a moment’s notice. That may require you to learn a new programming language like Python. Or maybe you need a primer on 3D game development. Or you might realize you could use a serious brush-up on iOS mobile creation.Point is, […]
