- 요약The field of micro-robotics has seen significant advancements in the recent years, including innovative actuation mechanisms for sub-millimeter robots, emergent behaviors in miniaturized robot swarms, and promising applications in critical industries such as healthcare, environmental surveying, defense, and security, among others. Despite the promising applications, the robot miniaturization faces additional challenges due to constraints on size, weight, power and cost (SWaP-C).This work focuses on enabling technologies to enhance micro-robot performance and system integration across the domains of mechanical engineering, electrical engineering, physics, chemistry, and computer science. Four projects are presented, each showcasing unique implementations of micro-robots with advancements in their sensing, actuation, intelligence and swarm capabilities. From the smallest 3-mm robots with no on-board systems to fully integrated robots measuring a few centimeters in size aiming to explore the extraterrestrial ocean, the work demonstrates the trade-offs between form factors and functionalities and pathways to meaningful integration at different scales.Collective behaviors enable micron- and millimeter-scale micro-robots to coordinate and carry out tasks beyond individual's capacity. Such behaviors are often preconditioned on the formation of high-density aggregations of the robot swarm. By leveraging the physics phenomenon of motility-induced phase separation (MIPS), we demonstrated for the first time the control of the degree of aggregation in a swarm of 300 3-mm microrobots without any integrated sensing or communication capabilities. The robot swarm is uniformly controlled by global vibration actuation frequency and magnitude, yet, due to changes in motion characterization and collision physics, the robots can be controlled to either disperse for coverage of the domain or aggregate into clusters. This project delves into the fundamental physics of controlling micro-swarm aggregation, which is broadly applicable to various micro-robot designs.Besides using global actuation control for inducing emergent swarm behaviors in microrobots, on-board piezoelectric thin-film actuators are integrated on individual micro-robots at a few centimeter scale. These micro-robots demonstrated a novel single-actuator steering mechanism based on the concept of mechanical resonance. The integrated thin-film piezoelectric actuator is used to induce different frequencies and excite various resonance modes achieved by asymmetrical robot design, allowing for frequency-controlled motion in the 2-dimensional plane. Compared to differential drive systems that use multiple motors or actuators, the novel use of a single actuator achieves the same functionality with scalable miniaturization prospects.The adoption of the single piezoelectric actuator steering mechanism preserves the precious space for critical integration of subsystems such as sensing and intelligence. In a 3-cm robot, the steering mechanism is accompanied by an autonomous vision system enabled by the integration of a camera and convolution neural network (CNN) based computer vision intelligence, presenting the first implementation of a fully autonomous micro-robot capable of searching and tracking targets at this scale.The final project intensifies the focus on system integration within micro-robotic platforms and their real-life applications. Developed for potential extraterrestrial oceanographic exploration on Jupiter's moon Europa, the micro swimming robot swarm is equipped with on-board communication, power, actuation, computation, and sensing subsystems. To minimize payload impact, these micro-robots are a few centimeters long, posing significant integration challenges. A custom multi-modal sensing module, developed using microelectromechanical system (MEMS) technology, equips the micro-robot with the ability to sense temperature, conductivity, pressure, pH, and biochemical markers simultaneously. Together with the swarm implementation, this sensing module aims to provide comprehensive data on Europa's ocean environment, assisting scientific understanding and the search for extraterrestrial life.In conclusion, this thesis advances the field of micro-robotics through innovative developments in actuation, sensing, and intelligence across various scales of micro-robots. The integration of multidisciplinary technologies has resulted in highly functional micro-robots with the potential for groundbreaking applications. Future research can build on these findings, aiming to overcome the challenges of SWaP-C constraints, further enhancing the capabilities and applications of micro-robots.
