Robot bee assembles in pop-up origami trick

Army-funded researchers at the Harvard Microrobotics Laboratory are popping out Harvard Monolithic Bees ("Mobees") from multi-layered, laser-cut blocks about the size of a quarter.

Inspired by pop-up books, the manufacturing process could allow for rapid production of dozens of flying robots and other electromechanical devices. The research is being published in the March edition of the Journal of Micromechanics and Microengineering.

In the RoboBees project, Pratheev Sreetharan and colleagues want to build bee-size robots that can fly and act autonomously as a colony. Until recently, it used a painstaking manual assembly method.

The prototype sheets consist of 18 layers of carbon fiber, titanium, brass, ceramic, adhesive sheets, and the plastic film Kapton. As seen in the vid below, the bee snaps together as it pops out of the laminate. … Read more

Could Sony's HX750 LED TV be a stealth value?

LAS VEGAS--As a rule, no company divulges pricing at CES anymore, but we still have reason to suspect that when its price actually does get announced, the Sony HX750 series might represent a good picture-quality-for-the-buck proposition.

This set is the least expensive in Sony's admittedly small 2012 CES announcement lineup to offer the edge-lit local dimming we liked so much on the NX720 from last year.

Sony has slowly begin competing in price in some TV categories over the last couple of years, and the HX750's feature mix eschews the MotionFlow 960 of the step-up HX850, settling for … Read more

Sony's best 2012 LED TV stays edge-lit, not full-array

LAS VEGAS--Much like Samsung this year, the best LCD-based TV Sony announced at CES is a non-full-array model, relying on edge-lit LEDs to produce its picture.

That's the bad news for videophiles expecting a full-array follow-up to the excellent XBR-HX929. The good news for said videophiles? Judging from the picture quality of the NX720 from 2011, Sony knows how to eke great black levels and minimal blooming from an edge-lit configuration.

It's curious that Sony didn't name the HX850, a TV its press release identifies as a "flagship," with the traditional "XBR" moniker. … Read more

Sony LED-based LCD TV shows monolithic style

As the first official 2010 HDTV reviewed by CNET, and the first mainstream edge-lit LED-based LCD produced by Sony we've tested, the KDL-NX800 series arrives with plenty of anticipation. However, before you equate "LED" with "awesome picture quality," it's worth reiterating that the backlight technology comes in a bunch of varieties--and not all are created equal. The Sony NX800 performs on a par with other like-equipped LCDs that we've tested, such as the UNB7000 series from Samsung, so people seeking a premium home theater picture might be disappointed.

In other areas, the … Read more
