Our articles, podcasts, and infographics inform our readers about developments in technology, engineering, and science. Because of the small scale, the airflow around a fly is much more viscous than that around birds or fixed-wing aircraft. What is more, it takes a lot of time to turn out a prototype with MEMS, and our design strategy entails building a lot of prototypes.Thin hinges of plastic embedded within a carbon fiber body frame serve as joints, and a delicately balanced control system commands the rotational motions in the flapping-wing robot, with each wing controlled independently in real-time. We are studying practical ways to emulate this system by using inputs from a number of attitude sensors that figure out the orientation of the fly and directly manipulate the actuators. These body parts are made of chitin, a common polysaccharide, which though tough is nonetheless substantially weaker than carbon fiber.

Still, we need not copy nature slavishly by putting up with limitations on invertebrate biology that electromechanical devices do not share. Designing these actuators to be as small and light as possible, while keeping them strong enough to deliver sufficient power, was our first key accomplishment. Flies achieve their astonishing maneuverability by moving their wings through complex, three-dimensional trajectories at frequencies that often exceed 100 hertz. It began when I took a stick-thin winged robot, not much larger than a fingertip, and anchored it between two taut wires, rather like a miniature space shuttle tethered to a launchpad.Because of this difference, the analytical tools that are used to predict the performance of an airplane are of little use in predicting the flight dynamics of an insect, making our job more difficult.

To make actuators that mimic real flight muscles, we add to the carbon-fiber-based composite a few layers of an electroactive material, which changes its shape when an electric field is applied. Play Inspired by the biology of a fly, with submillimeter-scale anatomy and two wafer-thin wings that flap at 120 times per second, robotic insects, or RoboBees, achieve vertical takeoff, hovering, and steering. Using the results from Dickinson’s models, I and others in Fearing’s lab set out to replicate the insect’s incredible wing motions.

This flying toy will be the perfect entertainment for the little ones at home. Even with basic control algorithms, however, we expect microrobots to be able to perform useful roles as ad hoc mobile sensor networks. For more flight time we will have to increase the battery’s energy density, make the propulsion more efficient, or develop energy-harvesting techniques, perhaps by mounting tiny solar panels on the insect’s back or converting the fly’s vibrations into electric current.

The Remote Control Flying Robot is perfect for first time pilots due to its durability and extra stable gyro with ultra-responsive flight controls. Designing a robotic insect is more complicated than simply shrinking a model airplane, however, because the aerodynamics that govern flight are entirely different on the scale of insects. Within milliseconds the carbon-fiber wings, 15 millimeters long, began to whip forward and back 120 times per second, flapping and twisting just like an actual insect’s wings. This interactive buddy is engineered to delight with its spectrum of glowing hues, turning every play session into an epic adventure. Additionally, their ease of use and the joy they provide during flight make them a favorite among enthusiasts of all ages.The power density of our robot’s actuators comes to more than 400 watts per kilogram, some four times that of an ordinary fly’s wing muscles. This i-Fly Infrared Control Robot comes in a striking black colour and is designed only for indoor flying.
