Talk Title: Gait coding scheme for multi-legged robots
Abstract: While the transport of matter by wheeled vehicles or legged robots can be guaranteed in engineered landscapes like roads or rails, locomotion prediction in complex environments like collapsed buildings or crop fields remains challenging. Inspired by principles of information transmission which allow signals to be reliably transmitted over noisy channels, we develop a “matter transport" framework demonstrating that non-inertial locomotion can be provably generated over “noisy" rugose landscapes (heterogeneities on the scale of locomotor dimensions). Experiments confirm that sufficient spatial redundancy in the form of seriallyconnected legged robots leads to reliable transport on such terrain without requiring sensing and control.
Despite robustness, locomotors with excessively redundant legs are often practically unfavored because of limited efficiency and applicability. Analogous to signal transmission, we further improve locomotion efficiency by properly coordinating (coding) the redundant legs. The challenges of such coding partially lie on the high dimensionality associated with the additional legs and the emergent importance of inter-leg centralized coordination. Specifically, we need a top-down approach to analyze the central coordination among the additional legs, and further design how it should adapt to different environments. We use geometric mechanics, a mathematical framework for studying locomotion in various systems, for motion planning in multi-legged robots operating in complex environments. As a result, open-loop operation on multi-legged robots achieves remarkable performance on terrains with different types and levels of complexity. Additionally, analogies from communication theory coupled to advances in coding for error detection/correction further improve the locomotion efficiency and robustness via centralized adaptation (using simple contact sensors to estimate environmental uncertainty). This research contributes to the field of legged robot locomotion, providing new possibilities for designing effective and adaptable robots for challenging environments.

Talk Title: Enabling Sustainable Propulsion and Clean Energy Transitions: Reacting Flow Modeling across molecular to continuum scales
Abstract: While the global demand for air travel continues to rise, the aerospace carbon footprint is increasingly concerning. In the near term, it is highly desirable for the rational design, efficient certification, and massive production of carbon-neutral fuels to mitigate greenhouse emissions. Furthermore, future aerospace vehicles will be integrated with highly efficient and high-speed propulsion devices using clean and renewable energy sources. The design of these sustainable and high-speed propulsion systems requires a fundamental understanding of reacting flow physics across multiple scales, featuring interactions between the molecular and the continuum flow scale.
In this talk, I will present state-of-the-art approaches to multiscale reacting flow modeling of sustainable aerospace energy carriers. The modeling spans from molecular scale using GPU-enabled quantum chemistry computation to continuum scale gas dynamics and turbulence-resolved flow modeling. I will first emphasize the reacting flow modeling of bio-derived sustainable aviation fuel (SAF), which is considered a near-term alternative to conventional jet fuels. I will then discuss the study of methane and natural gas as potential transition fuels, along with hydrogen and battery technologies for the long-term future. I envision that the presented approach will help not only to enable sustainable aviation but also to advance a clean and sustainable transition in the future energy landscape.
