Abstract:
Legged robots show great promise in navigating difficult environments. Even small legged robots can use their agility to overcome significant obstacles like their larger counterparts. However, much work remains to be done both in mechanical design and control to enable robots to apply these abilities outside the lab in the real world. This talk presents an overview of three relatively small robots that address different aspects of legged mobility (organized in increasing numbers of legs). The monoped Salto-1P explores agile leaping to enable a small robot to clear large obstacles, simple bipeds investigate how walking scales to smaller sizes, and perception and control for quadruped Spirit-40 tackle walking through entangling obstacles like vines.

Speaker: Wolfram Burgard
Professor and Founding Chair, Department of Computer Science & Artificial Intelligence at University of Technology Nuremberg
Editor-in-Chief at IEEE Transactions on RoboticsPresentation Title: "The Challenges to Realize Embodied AI"
Date: Wednesday, April 22 at 11:00 AM
Location: Tech, M416 and Zoom
https://tinyurl.com/CRBSeminarAbstract:
To ultimately achieve Embodied Artificial Intelligence, we need robots capable of robustly perceiving their environments and executing their actions. The key challenge is that no sensors and actuators are perfect, which means that robots need the ability to properly deal with the resulting uncertainty. Professor Burgard will discuss the opportunities of the probabilistic and deep-learning approaches to robotics and how they can be combined to get the best of both worlds. He will describe how we can utilize the potential of foundation models to even better deal with complex and changing real-world environments.Bio:

lessBiophysical modeling of synaptic plasticity
Abstract
Neurotransmission occurs at different length scales. Experiments have shown that neuronal structure and function are tightly coupled across these scales. In this talk, I will discuss recent efforts to develop quantitative models to understand these structure-function relationships. One focus is how the shapes of dendritic spines and the presence of organelles within them affect calcium transients in spines and dendrites. I will also present an example at the scale of axons, focusing on how the mechanics of the neuronal membrane influence axonal morphology and how the organization of the membrane periodic skeleton affects tension propagation along axons.

lessME512 Seminar Series Multimaterial Additive Manufacturing for Shape-Morphing Structures and 4D Printing Monday, May 4, 2026 3:00 PM L211 Tech
ABSTRACT Body 3D printing (additive manufacturing, AM), where materials are deposited in a layer-by-layer manner to form a 3D solid, has seen significant advances in recent decades. Multimaterial 3D printing has attracted significant research efforts in recent years. It offers the advantage of placement of materials with different properties in the 3D space with high resolution, or controllable heterogeneity. In this talk, we present our recent progress in developing multimaterial additive manufacturing methods. In the first approach, we present a new development where we integrate two AM methods, direct-ink-write (DIW) and digital light processing (DLP), into one system. In this system, the DLP can be used to print complex bulk parts while DIW can be used to print functional inks, such as conductive inks and liquid crystal elastomers. In the second approach, we recently developed a grayscale DLP (gDLP) 3D printing method where we use light intensity to control local properties and thus create structures with gradient material properties. We further investigate how to use machine learn to help the inverse design of 4D printing of shape-morphing structures with multimaterial additive manufacturing. BIO Dr. H. Jerry Qi is the Woodruff Professor in the George W. Woodruff School of Mechanical Engineering at Georgia Institute of Technology and is the site director of NSF IUCRC on Science of Heterogeneous Additive Printing of 3D Materials (SHAP3D). He received his undergraduate and graduate degrees from Tsinghua University and a ScD degree from MIT. After one-year postdoc at MIT, he joined the University of Colorado Boulder in 2004 and moved to Georgia Tech in 2014. Prof. Qi’s research is in the broad field of nonlinear mechanics of polymeric materials and focuses on developing fundamental understandings of multi-field properties of active polymers through experimentation and constitutive modeling, then applying these understandings to application designs. He has been working on a range of active polymers, including shape memory polymers, light-activated polymers, and covalent adaptable network polymers, for their interesting behaviors such as shape memory, light actuation, healing, reprocessing, and recycling. In recent years, he has been working on integrating active materials with 3D printing. He and his collaborators pioneered the 4D printing concept. He is a recipient of NSF CAREER award (2007), Sigma Xi Best Faculty Paper Award (2018), Gerhard Kanig Lecture by the Berlin-Brandenburg Association for Polymer Research (2019), the James R. Rice Medal from Society of Engineering Science (2023), the T. H. H. Pian Award from International Conference on Computational & Experimental Engineering and Sciences (2024), and the ASME Warner T. Koiter Medal (2024). He was listed as one of the highly cited researchers by Clarivate in 2024 and 2025

lessABSTRACT
GScientific Machine Learning (SciML) integrates data-driven inference with physical modeling to solve complex problems in science and engineering. However, the design of SciML architectures, loss formulations, and training strategies remains an expert-driven research process, requiring extensive experimentation and problem-specific insights. We introduce AgenticSciML, a collaborative multi-agent system in which over 10 specialized AI agents collaborate to propose, critique, and refine SciML solutions through structured reasoning and iterative evolution. The framework integrates structured debate, retrieval-augmented method memory, and ensemble-guided evolutionary search, enabling the agents to generate and assess new hypotheses about architectures and optimization procedures. Across physics-informed learning and operator learning tasks, the framework discovers solution methods that outperform single-agent and human-designed baselines by up to four orders of magnitude in error reduction. The agents produce novel strategies—including adaptive mixture-of-expert architectures, decomposition-based PINNs, and physics-informed operator learning models—that do not appear explicitly in the curated knowledge base. These results show that collaborative reasoning among AI agents can yield emergent methodological innovation, suggesting a path toward scalable, transparent, and autonomous discovery in scientific computing.

lessMechanics of architected materials across length and time scales
Abstract
Architected materials (or mechanical metamaterials) across length scales—from nanometers to centimeters— have enabled previously unachievable mechanical properties through a variety of 3D material morphologies. Significant advances in our understanding of these materials have thus pointed to structure-property relations that lead to unique macroscopic mechanical properties. Despite this progress, several hurdles have precluded widespread application of these materials to solve engineering challenges. First, clear routes to scalably design and fabricate these architected materials have remained elusive; with most designs reported to date targeting high stiffness but low deformability. Second, since most of the studies to date have characterized architected materials under quasi-static deformation, their dynamic-property regime remains to be fully characterized and understood—essential to a variety of envisioned applications. In this talk, we present efforts towards addressing these long-standing challenges, specifically by proposing routes for designing architected materials with extreme compliance and by presenting two types of high-throughput characterization methods that enable exploration of architected materials under dynamic conditions. We discuss efforts implementing and understanding compliant architected materials by proposing metamaterial design paradigms inspired by polymer-network architectures. We also present efforts performing non-contact characterization of materials through laser-induced vibrational signatures, providing a new route to uncover dynamic elastic responses of materials and unparalleled throughput rates. Lastly, we discuss efforts characterizing architected materials under extreme dynamic conditions through use of microparticle impact experiments at the microscale, shedding light on energy dissipation mechanisms that emerge from the use of 3D microstructure.
