Epson's 12 Gram Flying Robot

fraxinus-tree writes "Epson has developed a very small (8.6g w/o battery) flying device, something like a bluetooth-controled palm-top helicopter." Since it can carry 5 grams for only 3 minutes, I can't imagine much practical use, but it's still neat.

      Rotors are much easier to build: just a revolute joint. While a flapping wing would be a more efficient way to produce lift for a small aircraft, it would be incredibly challenging to produce an actuator which can produce the required motion of a bee's wings, particularly at the proper frequency and scale. The wings actually flap and then twist, or flip over, at the end of each stroke. This way they use the vortex that is shed during the previous stroke to provide a boost in lift on the return stroke because the vortex passes over the upper surface of the wing. This produces a much greater pressure differential than just a regular airfoil in a free stream, because the core of the shed vortex has a much lower pressure than what can be produced by an airfoil due to it's shape. Let's not forget the control system which would probably be a challenge to design.

      Maybe a good candidate for using a tiny ethanol-powered fuel cell? Low empty weight, direct fuel -> electricity conversion, and ethanol has fairly good energy-weight ratio (better than batteries anyway). You could even use a lightweight plastic bag as fuel tank.

    Seiko Epson Corporation ("Epson") today announced that it has successfully developed a lighter and more advanced successor to the FR, the world's smallest and lightest micro-flying robot. Turning once again to its micromechatronics technology, Epson has redefined the state of the art with its FR-II micro-flying robot--the world's new lightest and most advanced microrobot, which also features Bluetooth wireless control and independent flight*2. The FR-II will be on display at the Emerging Technology Fair, part of the Future Creation Fair that runs from August 27 to 30 at the Tokyo International Forum.

    Epson has long been engaged in the research and development of microrobots and in the development of applications for their enabling technologies. The FR-II is only the latest chapter in an Epson success story that began with Monsieur, a microrobot that was listed in the Guinness Book of Records as the world's smallest microrobot and was put on sale in 1993. Having made micromechatronics one of its core technologies, the company has since created and marketed several more microrobots in the EMRoS series*3. April 2003 saw the introduction of the Monsieur II-P, a prototype microrobot that operates on the world's thinnest microactuator (an ultra-thin, ultrasonic motor)*4 and is remote-controllable via a power-saving Bluetooth module. The following November, Epson unveiled the prototype micro-flying robot FR, which featured two ultra-thin, ultrasonic motors driving two contra-rotating propellers for levitation, plus the world's first*5 linear actuator stabilizing mechanism for attitude control during flight.

    However, the FR prototype microrobot's flying range was limited by the length of the power cord attaching it to an external battery, and although it was radio-controlled, it had to be kept within sight of the operator while flying. Consequently, Epson decided that the next step was to extend the flying range by developing fully wireless operation paired with independent flight capability. The main issue to be tackled with regard to wireless flight was the need to combine lighter weight with greater dynamic lift. Epson made the robot lighter by developing a new gyro-sensor that is a mere one-fifth the weight of its predecessor, making it the world's smallest and lightest*6 gyro-sensor. Also helping to shed weight is the high-density mounting technology used to package the microrobot's two microcontrollers including the Epson-original S1C33-family 32-bit RISC. Dynamic lift was boosted 30% by introducing more powerful ultra-thin ultrasonic motors and newly designed, optimally shaped main rotors. As for the challenge of independent flight, Epson brought its many years of micromechatronics experience to bear in realizing the development of a linear actuator with faster response time and a high-precision attitude control mechanism, and a flight path control and independent flight system (primarily for hovering).

    To top it off, Epson added an image sensor unit that can capture and transmit aerial images via a Bluetooth wireless connection to a monitor on land, and they also devised two LED lamps that can be controlled as a means of signaling. Epson was assisted by Chiba University's Nonami (Control and Robotics) Laboratory in developing the control system for independent flight. The company also received advice on the rotor design from the Kawachi (Aeronautics and Astronautics) Laboratory at the University of Tokyo.

    The key concept behind Epson's R&D efforts in micro-flying robots has been to expand the horizons of microrobot activities from two-dimensional space to three-dimensional space. Now, with the successful implementation of Bluetooth communications and independent flight in the FR-II, Epson has literally added a new dimension to microrobotics while greatly expanding the potential range of microrobot applications by incorporating image capture and transmission functions. At the Emerging Technology Fair, the FR-II micro-flying robot's features are expected to be showcased in artistic aeria

  17. Autonomous Applications by Embedded+Geek · · Score: 4, Insightful
    Many posters have posted ideas about using this thing as a simple remote controlled helicopter (reconisance, corporate espionage, etc). While that's kinda neat, it misses the real value of this thing.

    If it can fly autonomously (not possible yet if you have to add more equipment like balance or barometric sensors and blow the thing's payload - but you can put the brainpower in the base station), it opens up a whole new world of possibilities. It could fly point to point in a warehouse on a security patrol, recharging at stops along the way. Automated inspections (attics, structual beams in large buildings, etc) could be done in detail with less strain on a manual pilot - you building inspector just watches the monitor and doesn't bother trying to fly the thing.

    The big thing, of course, is adapting this technology to be used outside. Think of a swarm of these released from roadside base stations to check freeway bridges, dams, or structures, minutes after an earthquake. Or a version that works in fluid (really, a submarine) checking ship hulls for damage - on infestations of foreign organisms like zebra mussels - as they steam into port.
