Robot in the Sky! (almost)

Seiko Epson Corp. showed off their flying micro-robot at this week's International Robot Exhibition in Tokyo. EE Times reports that ultrasonic wristwatch motors keep the 8.9 grab machine airborne. It's also outfitted with Bluetooth and several microsensors including a gyro and camera. Right now though, battery weight keeps it tethered to its power supply. (The photo is from Yahoo! News.)
