A recent press release from Epson about the FR-II micro robot has generated a lot of story submissions lately. The FR-II is powered by two ultrasonic motors which drive opposing rotors. The tiny robot is just 136mm x 85mm, weigh 12.3 grams including two gyros, batteries, bluetooth link, and a digital camera. It has a flight time of about 3 minutes. You can see photos and read more about the robot at the BBC, space.com, and Slashdot. Meanwhile, Gizmodo reminds us of the Pixelito which, while it is an R/C helicopter and not a true robot, weighs in at only 6.9 grams.
