Here's a diagram of the uFR.

My hunch is that this is for the government. Not for us.

<The prototype four-legged robot weighs just 10 grams (0.35 ounces) and measures 70 millimeters (2.8 inches) in height. It can be operated by remote control but at present it must be powered via a 1.5-meter-long (5.0-feet) cable connected to an electric generator. It took Seiko Epson three years to develop the Micro Flying Robot, Ajioka said while declining to give financial details The company hopes the robot will eventually fly independently using an onboard battery but so far has been unable to find a suitably lightweight power source. "That's why we showed this robot at the exhibition. We want to attract battery makers who can manufacture a very light battery for us," Ajioka said, adding the company had yet to set a date for marketing the robot. >
