Faster Than Us: Meet DARPA’s LS3 & Cheetah Robots

Today, DARPA [Defense Advanced Research Projects Agency] showed off its latest creation, the Legged Squad Support System or LS3, robotic ‘pack mule’ prototype, 4-legged robots. Outfitted in camo for now, the next evolution of these will probably be covered in skins allowing them to better blend into the wild.

Putting Out Flames With Sound

Did you know that audio frequencies can be used to put out fires? Watch this…

Performers on DARPA’s Instant Fire Suppression program evaluated an acoustic approach to suppressing flames. In this video, a flame is extinguished by an acoustic field generated by speakers on either side of the pool of fuel. Two dynamics are at play in this approach.

First, the acoustic field increases the air velocity. As the velocity goes up, the flame boundary layer, where combustion occurs, thins, making it easier to disrupt the flame. Second, by disturbing the pool surface, the acoustic field leads to higher fuel vaporization, which widens the flame, but also drops the overall flame temperature. As the same amount of heat is spread over a larger area, combustion is disrupted.

The Internet, Technology, Politics & The Future

There is a lot to learn from the events that have been unfolding in England and it will be particularly interesting to see what roles the internet, technology, politics and community will play in this historic event.

Throughout the last few days we have seen a chaotic flood of real-time citizen journalism, reports extending from the hyper-local to the world community at large, all tuned in and sharing information. Social media and mobile technologies have played a big role and we’ve seen examples of these platforms being heavily used to coordinate the flow of information. Whether its been recording and uploading mobile photo, video and audio footage, groups dedicated to organizing clean up efforts, open-data community mapping of incidents, crowd sourced justice groups pointing out self-professed looters and individuals caught on surveillance cameras [CCTV] or identifying people via images using the same facial recognition technology that up until recently was mostly only looked as a social tagging tool.
