Journal ArticleDOI
Untethered flight of an insect-sized flapping-wing microscale aerial vehicle
Noah T. Jafferis,Noah T. Jafferis,E. Farrell Helbling,E. Farrell Helbling,Michael Karpelson,Robert J. Wood,Robert J. Wood +6 more
TL;DR: This insect-scale aerial vehicle is the lightest thus far to achieve sustained untethered flight (as opposed to impulsive jumping8 or liftoff) and matches the thrust efficiency of similarly sized insects such as bees.
Journal ArticleDOI
Driving high voltage piezoelectric actuators in microrobotic applications
TL;DR: In this article, the authors describe electrical characteristics and drive requirements of low mass piezoelectric actuators, the design and optimization of suitable drive circuit topologies, aspects of the physical instantiation of these topologies including the fabrication of extremely lightweight magnetic components, and a custom, ultra low power integrated circuit that implements control functionality for the drive circuits.
Proceedings ArticleDOI
A review of actuation and power electronics options for flapping-wing robotic insects
TL;DR: This paper explores the design space of flapping-wing microrobots weighing lg and under by determining mechanical requirements for the actuation mechanism, analyzing potential actuation technologies, and discussing the design and realization of the required power electronics.
Proceedings ArticleDOI
An untethered jumping soft robot
Michael T. Tolley,Robert F. Shepherd,Michael Karpelson,Nicholas W. Bartlett,Kevin C. Galloway,Michael Wehner,Rui M. D. Nunes,George M. Whitesides,Robert J. Wood +8 more
TL;DR: An untethered soft-bodied robot that uses a combination of pneumatic and explosive actuators to execute directional jumping maneuvers and a thermodynamic model for the combustion of butane used to power jumping is presented.
Journal ArticleDOI
Progress on 'pico' air vehicles
Robert J. Wood,Benjamin M. Finio,Michael Karpelson,Kevin Y. Ma,Nestor O. Perez-Arancibia,Pratheev Sreetharan,Hiro Tanaka,John P. Whitney +7 more
TL;DR: Progress is presented in the essential technologies for insect-scale robots, or ‘pico’ air vehicles, as the characteristic size of a flying robot decreases.
