Research Topic Description, including Problem Statement:
Autonomous millimeter-scale robots will be a powerfully effective and low-cost tool with broad application. To be realized, however, numerous challenges must first be solved, including mobility, energy, sensing, communication, and control. Moreover, these challenges must be solved simultaneously for microrobotics to work effectively on specific problems. Microrobotics is an intensively interdisciplinary field. IC Postdoc Program is funding innovative research on the "Design and Control of Heterogeneous Microrobot Swarms," based on aerial microrobot platforms that 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.
The inherent trade-offs among the 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 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 generic access network (GaN) power transistors and high-Q micro-electromechanical systems (MEMS) inductors).
A nanotech approach would require more basic research, but represents the appropriate applicable scale to microrobotics and various approaches. Energy harvesting via nanoscale machines (researchers have demonstrated success with a mesoscopic ratchet to collect dissipated heat energy) or development of thermal effusive materials, the creation of new super capacitating electrolytic surfaces or an entirely new class of bio-batteries illustrate the potential for nanoscale energy production.
Relevance to the Intelligence Community:
Microrobotics represents a promising future technological wave capable of meeting persistent monitoring and surveillance requirements against priority issues at low cost, 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.
