Climbing robot can scale walls on a supersonic stream of air, won't leave fingerprints behind

There are plenty of wall climbing robots roaming the Earth, but few can scale heights as gracefully as this little guy can. Developed by researchers at the University of Canterbury in New Zealand, this bot can wind its way across any glass, metal or cloth terrain, without even touching its pods to the surface. The secret lies in Bernoulli's Principle, which states that as the speed of a fluid increases, its pressure decreases. This phenomenon also applies to streams of air, which, when moving at high speeds around of a circular gripper, can create a vacuum strong enough to hold things without actually touching them. In this case, air shoots out of the robot's feet at more than 2,000 miles per hour, creating enough pressure to lift the craft, while holding it close to the wall. The technology isn't new, but rarely can it support the weight of an entire device -- let alone the extra cargo that this climber's non-contact adhesive pads can hold. Researchers say the supersonic grippers will be available in "some months" and will probably cost "a few hundred dollars." As for the bot itself, Canterbury's engineers envision it being used for industrial inspections -- though the more we think about it, the more we realize just how dirty our windows are.

iPhone 5 may feature curved glass screen, continue iPod nano legacy

DigiTimes has been canvassing its manufacturing industry sources again, and today it's managed to extract some intel regarding Apple's typically secretive supply chain. Steve Jobs' team are said to have purchased between 200 and 300 glass-cutting machines, specifically in order to use them to slice up curved glass display covers for the iPhone 5. This move has apparently been in an effort to accelerate production, with glass makers reportedly showing a reluctance to buy the machinery themselves due to its prohibitive cost. Lest you think this sense of urgency might accelerate the iPhone 5 from its earlier-rumored September launch, DigiTimes also reports that yields of curved glass are not yet good enough to start using said fancy machines. So the iPhone may be headed for the same curvacious look as we've already seen on Dell's Venue and HTC's Sensation (or maybe even the concavity of the Nexus S), but as is Apple's wont, it looks like that will be done with a tailor-made, custom solution. At least those Cupertino designers have a couple of generations of curved iPod nano screens under their belt, giving them a good idea of how to handle the atypical glass frontage. Now if we could just have a good idea of when this phone will actually be on sale...
