Robobees Harvard's Flapping-Wing Micro Robots

Robobees

A convergence of body, brain, and colony
Overview of the Micro Air Vehicles Project

INSPIRED by the biology of a bee and the insect’s hive behavior ...

we aim to push advances in miniature robotics and the design of compact high-energy power sources; spur innovations in ultra-low-power computing and electronic “smart” sensors; and refine coordination algorithms to manage multiple, independent machines.

Science Nation - RoboBees: Design Poses Intriguing Engineering, Computer Science Challenges - YouTube



It started with a TV show, "Silence of the Bees," about honeybee populations in steep decline. At Harvard University, electrical engineers Rob Wood and Gu-Yeon Wei, and computer scientist Radhika Nagpal saw a challenge. And, so began the creation of the "RoboBee," a miniature flying robot, inspired by the biology of a bee and the insect's hive behavior. With support from the National Science Foundation and a program called Expeditions in Computing, Wood put together a diverse team of collaborators to get the RoboBee project off the ground. [...]

Flapping-wing microrobots
As the characteristic size of a flying robot decreases, the challenges for successful flight revert to basic questions of fabrication, actuation, fluid mechanics, stabilization, and power - whereas such questions have in general been answered for larger aircraft. When developing a flying robot on the scale of a common housefly, all hardware must be developed from scratch as there is nothing "off-the-shelf" which can be used for mechanisms, sensors, or computation that would satisfy the extreme mass and power limitations.

Micro-robot

Developed at Duke University, each micro-robot is shaped like a spatula but with dimensions measuring just microns, or millionths of a metre.

They are almost 100 times smaller than any previous robotic designs of their kind and weigh even less.

In videos produced by the team, two micro-robots can be seen pirouetting to the music of a Strauss waltz on a dance floor just 1mm across.

While so far MEMS research has been biased more towards sensor technology, there are a large number of potential applications that require micro actuators. Important examples are techniques to efficiently move, sort, or mix small particles (e.g. cells in biotechnology applications); or micro positioning devices for inspection and assembly of complex micro systems (e.g. for display or amplifier arrays).
