We present a skin-shear actuator based on the lead screw mechanism. The lead screw mechanism is simple, reliable, offers fewer components, and accommodates into compact form- factors. We show mechanical design of a single assembly unit and implement

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 larg

The challenges for successful flight of insect-scale micro air vehicles encompass basic questions of fabrication, design, propulsion, actuation, control, and power - topics that have in general been answered for larger aircraft. When developing a fly

Here we present the design, modeling, and fabrication of a 2g mobile robot. By applying principles from biology and existing meso-scale fabrication techniques, a 5.7cm hexapod robot with sprawled posture has been created, and is capable of locomotion

The Harvard/Planetary Society all-sky optical SETI marked a significant increase in search capability and instrument complexity. It is the first all-sky optical search, the first optical search with multiple sky pixels (there are 512 in the all-sky s

We report initial results from the Harvard/Planetary Society all-sky search for pulsed optical signals from other civilizations, which saw "first light" on 11 April, 2006 after six years of planning and construction. To survey of the Northern sky (-2

Silicon-based MEMS techniques dominate sub-millimeter scale manufacturing, while a myriad of conventional methods exist to produce larger machines measured in centimeters and beyond. So-called mesoscale devices, existing between these length scales,
