New Mass-production Technique, Robotic Insects Spring to Life
Production method inspired by children's pop-up books enables rapid fabrication of tiny, complex devices. Read full article at the Harvard website HERE. Video 1: The Harvard Monolithic Bee is a millimeter-scale flapping wing robotic insect produced using Printed Circuit MEMS (PC-MEMS) techniques. This video describes the manufacturing process, including pop-up book inspired assembly. This work was funded by the NSF, the Wyss Institute, and the ASEE. <iframe width="853" height="480" src="http://www.youtube.com/embed/VxSs1kGZQqc" frameborder="0" allowfullscreen></iframe> Video 2: The Harvard Monolithic Bee undergoing pop-up 3D assembly. <iframe width="853" height="480" src="http://www.youtube.com/embed/PqUOOf-1SSU" frameborder="0" allowfullscreen></iframe> Video 3: A demonstration of pop-up assembly of an icosahedron (20 sided polygon). The device is fabricated flat but assumes a nearly spherical shape, potentially useful for omnidirectional sensing. <iframe width="640" height="480" src="http://www.youtube.com/embed/cUu9lQV0XBE" frameborder="0" allowfullscreen></iframe> Photo 1: The Harvard Monolithic Bee (or "Mobee") pops up within an assembly scaffold, which performs more than 20 origami assembly folds.

Using the old, manual process, every one of those parts would have to be cut, folded, assembled, and glued by hand. The bottom image illustrates the 18 layers of laser-cut materials that create the pop-up structure. Images courtesy of Pratheev Sreetharan.  ·  ·  · |

<iframe width="853" height="480" src="http://www.youtube.com/embed/GgR-mH6X5VU" frameborder="0" allowfullscreen></iframe> A prototype of "RoboBee", a project funded by the National Science Foundation to build a fully-functional, insect-sized robotic bee capable of autonomous flight. This video shows a series of early, uncontrolled takeoff tests proving that the vehicle can generate enough lift to overcome its own weight; however no stability control is implemented. The Harvard Microrobotics Lab is part of the Harvard School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering.
