Applying Digital Twin Technology to Rotating Mechanical Systems and Space Applications
Abstract
Digital twin (DT) technology is transforming industries by creating digital replicas of physical entities, yet its full potential is hindered by the complexity of modeling and integrating diverse data types. The research focuses on enhancing DT applications through the integration of verification and validation (V&V) with Weighted Flow Matching (WFM). It examines how V&V improves data reliability in rotating mechanical systems and assesses WFM’s role in refining data-driven generative modeling. A meta-learning-based reweighting algorithm (LRW) is introduced to dynamically assign weights to training samples based on their gradient directions, thereby optimizing model robustness against noisy or biased data. Experiments involving rotating machinery and space applications demonstrate improved predictive accuracy, reliable fault diagnosis, and effective system analysis. This integrated approach strengthens DT technology by ensuring more precise system analysis, enhanced model predictive control, and robustness in complex scenarios.

Design of Resilient, Engineered, Autonomous, and Multifunctional (DREAM) Structures
Abstract
This talk will discuss strategies for the design of a new generation of intelligent structures equipped with sensors and control devices that can react in real time during multiple hazards. We create these adaptive structures with human-like capabilities by using agent-based modeling, vibration control, and evolutionary game theory. We modified a patented neural dynamic model for seismic design optimization of diagrid buildings, rocking-steel braced frames, and related structural systems. We also investigate integrative design methods to simultaneously design the structure and control devices, optimal placement of sensors, and distribution of tasks during failure mechanisms. We study control methodologies for novel testing technologies such as real-time hybrid simulation that combines numerical and experimental substructures. This unique intersection allows for design studies looking at aerodynamic mitigation through the origami-inspired morphing building envelope, and biomimicry design applying aquatic life adaptations and patterns into urban planning and structural design.

From Coordination to Collaboration in Multi-Robot Systems: Lessons from Ecology
Abstract
A standard approach to multi-robot systems is to divide the team-level tasks into suitable building blocks and have the robots solve their respective subtasks in a coordinated manner. However, by bringing together robots of different types, it should be possible to arrive at completely new capabilities and skill-sets. In other words, the whole could become greater than the sum of its parts. Inspired by the ecological concept of a mutualism, i.e. the interaction between two or more species that benefit everyone involved, this idea is formalized through the composition of barrier functions for encoding collaborative arrangements in terms of expansions and contractions of relevant sets. Contextualized in a long-duration setting for robots deployed over long time scales, where optimality has to take a backseat to “survivability”, example scenarios include robotic environmental monitoring, safe learning, and remote access in the Robotarium, which is a multi-robot lab that has been in (almost) continuous operation for over five years.

Embodied Intelligence in Bionic Limbs
Abstract
Recent developments in the design of bionic limbs increasingly emphasize the importance of human-centered principles in creating intelligent systems that can operate seamlessly within complex, dynamic environments and interact naturally with users. This talk explores the challenges of achieving embodied intelligence in lower-limb prostheses, and presents results in key methodologies, including compliant actuator design and AI-based control architectures. These innovations not only have the potential to enhance the functionality of the prosthesis but also to significantly improve the intuitiveness of the user experience and, ultimately, to improve their quality of life.
