Description

Research Topic Description, including Problem Statement:

Autonomous millimeter scale robots will be a powerfully effective and low cost tool with broad application. However, numerous challenges must first be solved, including mobility, energy, sensing, communication, and control. Moreover, these challenges must be solved simultaneously for microbots to work effectively on a specific problem. Microrobotics is an intensively interdisciplinary problem. The Intelligence Community (IC) Postdoctoral Fellowship Program has funded research to continue innovative research on the "Design and Control of Heterogeneous Microrobot Swarms" based on aerial microrobot platforms, which use electrohydrodynamic (EHD) thrust to fly silently, and with no moving parts. This research takes a unique approach to overcome thrust-to-weight challenges that trouble microrobotic development. True to the interdisciplinary nature of the field, initial success highlights the need for concurrent research and improvement in energy applications, specifically improved performance in DC-DC voltage conversion. These EHD- and other dielectric elastomer-, electrostatic-, or piezo-based microrobotic actuators all require high power density, miniaturized, and high voltage ratio converters that sit in a unique design space outside the typical purview of high performance power electronics.

Example Approaches:

The inherent trade-offs between operating frequency, the number of voltage multiplier stages, and the availability of suitable high-voltage diodes and high-frequency magnetic material are limiting the achievable specific power of state-of-the-art high voltage converters and slowing down the progress of many exciting fields. While commercially available solutions may have specific powers suitable for larger and/or grounded robots, they are unsuitable for centimeter- and millimeter- scale robotics. There is potential for high impact work studying both new circuit topologies (e.g., high frequency switching resonant circuits) and new devices to populate them (e.g., high performance GaN power transistors and high-Q MEMS inductors).

A nanotech approach would require additional basic research but represents the appropriate applicable scale to microbotics and a variety of different approaches. Energy harvesting, via nanoscale machines (a mesoscopic ratchet to collect dissipated heat energy demonstrated in work led by French researchers Roche and Rolleau), or development of thermal effusive materials (Cottrill, MIT); the creation of new super capacitating electrolytic surfaces (T.Allan Hatton, MIT and J.Eastoe Uni Bristrol); or an entirely new class of bio-batteries (S.Heilshorn, Stanford). These approaches, and many others, illustrate the potential for nanoscale energy production.

Relevance to the Intelligence Community:

Mircrorobotics represent a promising new future technological wave capable of meeting persistent monitoring and surveillance requirements against priority issues at low costs, but only if several vexing technical problems—including, mobility, sensing, communication and control—can be resolved. Progress in these areas would improve the IC’s ability to monitor, warn, and provide senior leaders the decision space to address numerous dangerous and destabilizing issues.
