The Space Review: Breaking up may be good to do - 6 views

    I especially like " The program will also create a "developer's kit" of open hardware and software specifications to make it easier for new components to integrate into such fractionated systems." Joris: wanna take the lead on having a closer look on this, I definitely would like to be part of it and happy to contribute, possibly also Juxi? - first assessment by Christmas realistic?
  •  
    I think it a very interesting approach. If you google "darpa F6", you should see that a lot seems to be on-going. So, should we do something about it before having the conclusions of the darpa study ?
  •  
    wait and see is never a good approach in these cases .... first step has to be anyway to understand what they are up to and then to think about our own ideas on it, own approaches, alternatives and then to see what we can do specifically in the team on it.

    lol, while ESA is sending around memos and its managers are spending time talking about validation and verification of AI methods ... US / DARPA is already 5-6 years ahead. Hopefully the ACT can contribute to this with our DA based approach ....

Why a Chip That's Bad at Math Can Help Computers Tackle Harder Problems - 1 views

  •  
    DARPA funded the development of a new computer chip that's hardwired to make simple mistakes but can help computers understand the world. Your math teacher lied to you. Sometimes getting your sums wrong is a good thing. So says Joseph Bates, cofounder and CEO of Singular Computing, a company whose computer chips are hardwired to be incapable of performing mathematical calculations correctly.
  •  
    The whole concept boils down to approximate computing it seems to me. In a presentation I attended once I prospected if the same kind of philosophy could be used as a radiation hardness design approach, the short conclusion being that surely will depend on the functionality intended.

New DARPA challenge wants unique algorithms for space applications - 4 views

  •  
    "On March 28, the Defense Advanced Research Projects Agency will kick of another one of its highly successful challenges this time looking for teams or individuals to develop unique algorithms to control small satellites on-board the International Space Station. " Will the ACT participate?
  •  
    That would be wrong on so many levels...
  •  
    Could not find out what the prize money is? Also does not seem clear to me how three cubes can catch an object "flying" in the opposite direction... But the approach is nice to see

Google combines skycrane, VTOL and lifting wing to make drone deliveries - 6 views

  •  
    Nice video featuring the technology. Plus it comes with a good soundtrack! Google's project wing uses a lifting wing concept (more fuel efficient than normal airplane layouts and MUCH more efficient than quadrocopters) but it equips the plane with engines strong enough to hover in a nose up position, allowing vertical landing and takeoff. For the delivery of packages the drone does not even need to land - it can lower them on a wire - much like the skycrane concept used to deliver the Curiosity rover on Mars. Not sure if the skycrane is really necessary but it is certainly cool. Anyways, the video is great for its soundtrack alone! ;-P

    could we just use genetic algorithms to evolve these shapes and layouts? :P
  •  
    > Not sure if the skycrane is really necessary but it is certainly cool. I think apart from coolness using a skycrane helps keep the rotating knives away from the recipient...
  •  
    Honest question, are we ever going to see this in practice? I mean besides some niche application somewhere, isn't it fundamentally flawed or do I need to keep my window opened on the 3rd floor without a balcony when I ordered something from DX? Its pretty cool yes, but practical?
  •  
    Package delivery is indeed more complicated than it may seem at first sight, although solutions are possible for instance by restricting delivery to distribution centers. What we really need of course is some really efficient and robust AI to navigate without any problems in urban areas : ) The hybrid is interesting since it combines the advantage of a Vertical Takeoff and Landing (and hover), and a wing for more efficient forward flight. Challenges lie in the control of the vehicle under any angle and all that this entails also for higher levels of control. Our lab has first used this concept a few years ago for the DARPA UAVforge challenge, and we had two hybrids in our entry last year for the IMAV 2013 (for some shaky images: https://www.youtube.com/watch?v=Z7XgRK7pMoU ).
  •  
    Fair enough, but even if you consider advanced/robust/efficient AI, why would you use a drone? Do we envision hundreds of drones above our heads in the street instead of UPS vans, or postmen, considering delivers letters might be more easily achievable. I am not so sure if personal delivery will take this route. On the other hand, if the system would work smoothly, I can image that I'm send a mail with the question whether I'm home (or they might know already from my personal GPS tracker) and then notify me that they are launching my DVD and it will come crashing into my door in 5min.
  •  
    I'm more curios how they're planning to keep people from stealing the drones. I could do with a drone army myself and having cheap amazon or google drones flying about sounds like a decent source.

Introducing A Brain-inspired Computer [IBM TrueNorth] - 0 views

  •  
    Built in Silicon technology (Samsung's 28 nm process), its power is measured as one million neurons and 256 million synapses. It contains 5.4 million transistor being the largest IBM chip in these terms. All this said, it consumes less than 100 mW!! "These systems can efficiently process high-dimensional, noisy sensory data in real time, while consuming orders of magnitude less power than conventional computer architectures." IBM is working with initLabs to integrate the DVS retinal camera with these chips = real time image neuro-like image processing. In what seems to be a very successful project hugely funded by DARPA, "Our sights are now set high on the ambitious goal of integrating 4,096 chips in a single rack with 4 billion neurons and 1 trillion synapses while consuming ~4kW of power."
