So the microfluidic logic isn't too amazing, it's just an oscillator. And I agree with that this is a brief synopsis of some interesting work. What I don't understand is why this is in Nature. They did something cool, but the

This may not be exactly what you are looking for, but check out the Linux 802.11n CSI Tool. A lot of this work is done with the channel state information(CSI) which tells you how a signal propagates from transmitter to receiver and vice ver

Today at 2:55 EST Philip Lubin, who is involved with the Starshot project, will present some work on the study he is doing for NASA investigating the feasibility of this. You can watch it live here: http://livestream.com/vie

Well using laser propulsion, we might be able to get a very lightweight probe up to 1/4 c using technology that isn't too far off.[0] Coincidentally, the group working on this will be presenting some of their most recent work on t

The big attraction of the ISS is laboratory where gravity can 'removed,' which can be useful for understanding processes on Earth. This is valuable to some companies. Right now a couple companies are currently running experiments

The Lake Kivu gas extraction project or Kivuwatt as it is called is some what new actually, and there is an interesting article about it here[0]. It is probably one of the strangest energy extraction projects in the world. [0] https:/&

No, but the bigger issue may be from laser jammers[0]. Laser jammers are used to jam police speed lidars to prevent them from obtaining a reading on vehicles. Such devices are legal in most places, because the optical spectrum does not fall

This is an absolutely terrible article, it seems the author just quickly threw together a list of alternative computing technologies and added a clickbaity title. Fluidics as a post Moore's law computing technology is laughable. The ma

Musk's reasoning is as follows: computer vision is getting better and cameras will always be cheap. We use LIDAR today because computer vision isn't that great. Although, LIDARs and sensors that do the same thing as LIDAR are gett

Well that might be a bit too 'new' for today's smartphones and rapid app development cycles. However, there is a software known as PTAM that has been around for a while now[0]. It isn't as fancy as the SLAM demo you show

It's also contingent on NASA using the SLS as a launch system[0]. [0] http://www.thespacereview.com/article/3025/1

One possibility here, is that the robot may not be able to sense obstacles that are too close and too short, IE kids. Some sensors have a minimum sensing range, meaning if an obstacle is too close the sensor doesn't see it. The kinect

This reminds me of a researcher I met, they were proposing to add a vast array of sensors to each wheel of a military vehicle that had at minimum 8 wheels. Every wheel would have rotation sensors, torque sensors, vibration sensors, a camera

Well as it happens there are special sonar cameras out there capable of providing real-time video images[0][1]. The use case here is being able for a diver or ROV to see in murky water [0] http://www.soundmetrics.com/image-ga

Fighter jet AIs aren't that scary compared to the work being done on algorithms for teams of robot soldiers. The US's TARDEC and the Australian DSTO held a competition for this back in 2010 called Multi Autonomous Ground-robotic I

Robots are currently bumbling electric imbeciles and do not perform well in such adversarial scenarios. They are also more fragile than they seem. One could permanently modify the robot's kinematics with the swift impact of an office c

If it really is using all electric actuators that's pretty big. This would be one of the first of Boston Dynamics' all electric robots. What exactly does using electric actuators over hydraulics buy us? Less noise, greater efficie

We use series elastic actuators not so the joints are more biological, but mainly so that motors don't get creamed when the robot bumps into something and so that the robot doesn't cream whatever it bumps into. The second reason w

I agree with you. I'm not trying to say that exoskeletons lack applications, just that the whole 'power-loader' concept is a bit silly. GE wanted the user of the hardiman to be able to pick up a 1.5 ton load and walk around w

Part of the problem was(and still is) that it didn't have very many good use cases. For the problem of moving heavy stuff around a forklifts, cranes, and carts performed much better. Not to mention the potential for serious injury to t

Now we just need to develop UAS's with eagle countermeasures. Lucky for us there is a compound that behaves like capsaicin does in humans but with birds. Methyl anthranilate[0], the chemical responsible for grape flavor in koolaid, bub

Even if you could hide a wireless reader and transmitter in a floppy disk, you would still be able to pick it up on X-ray. It would be very difficult to differentiate an SD card with a malicious payload even if one X-rayed it.

It is also worth mentioning that Lego makes a great mechanical prototyping medium. A big advantage is being able to quickly iterate and demonstrate something that works in the real world. In simulation, it's easy to forget about things

Well if you include Lego technic, Lego is in fact Turing complete[0][1]. This means one could not only do software design, but development on Lego. [0] http://rubens.ens-lyon.fr/fr/gallery/ [1] http://w

The hype is real and I really hope HP doesn't fuck this up. HP seems to have invented a new additive manufacturing process(if you have prior art let me know!) that does the same thing as laser sintering except without a laser. Getting
