These material technologies are composed almost entirely out of soft matter – elastomers, gels, and conductive fluids like liquid metal – and represent the building blocks for machines and electronics that are soft, flexible, and stretchable. Because of their intrinsic compliance and elasticity, such devices can be incorporated into soft, biologically-inspired robots or be worn on the body and operate continuously without impairing natural body motion. In this talk, Prof. Majidi will review recent contributions from his research group in creating soft multifunctional materials for wearable electronics and soft robotics using these emerging practices in “soft-matter engineering.” In particular, he will focus on soft robots powered using shape memory materials and soft material architectures for highly stretchable digital electronics, wearable energy harvesting, and electrically-responsive actuation. When possible, he will show how the design and operation of these soft-matter technologies can be guided by theoretical modeling methods based on principles of mechanics and discrete differential geometry. In addition to presenting his own research in the field, Prof. Majidi will also briefly review broader efforts and emerging challenges in utilizing soft multifunctional materials for applications in wearable electronics, bioelectronic interfaces, and soft robotics.
Bio: Carmel Majidi is the Clarence H. Adamson Professor of Mechanical Engineering at Carnegie Mellon University, where he leads the Soft Machines Lab. His lab is dedicated to the discovery of novel material architectures that allow machines and electronics to be soft, elastically deformable, and biomechanically compatible. Currently, Prof. Majidi's research is focused on modeling, design, and control of soft robotic systems as well as the development of multifunctional materials that exhibit unique combinations of mechanical, electrical, and thermal properties and can function as “artificial” skin, nervous tissue, and muscle. Prof. Majidi has received grants from industry and federal agencies along with early career awards from DARPA, ONR, AFOSR, and NASA to explore challenges in soft-matter engineering and robotics. Prior to arriving at CMU, he had postdoctoral appointments at Harvard and Princeton Universities and received his PhD in Electrical Engineering at UC Berkeley.

lessGuiding with Touch: Haptic Feedback for Enhancing Human Motor Performance
Recent advances in virtual reality simulation and robotics have changed the way that motor skills are trained, yet the feedback that most trainees receive when working in these environments is still delayed, subjective, and qualitative, which does not provide the maximum support for rapid acquisition of motor skill. In this talk, I will describe our research on identifying objective and quantitative metrics that capture motor skills in a few different tasks, and I will present our methods for employing real-time haptic feedback and guidance. We have shown that different implementations of haptic guidance provided via kinesthetic feedback can have either negative, neutral, or positive effects on motor performance and skill acquisition. More recently, we have shifted to provide cutaneous haptic feedback for guidance or performance feedback. We have shown that low-level properties of movements (e.g., smoothness) made in the performance of several motor tasks—including surgery in both virtual and robotic environments—are highly correlated with high-level performance outcomes. We encode these movement properties as simple haptic cues that are conveyed to the trainee in real-time, and evaluate the effect on skill acquisition. This talk will highlight our progress over the past decade in implementing real-time haptic feedback via wearable devices to train complex motor skills.
Marcia O’Malley’s research addresses issues that arise when humans physically interact with robotic systems, with a focus on wearable robotics and haptics for training and rehabilitation in virtual environments. She has twice received the George R. Brown Award for Superior Teaching at Rice University. O’Malley was a recipient of both the ONR Young Investigator award and the NSF CAREER Award. She is a Fellow of the American Society of Mechanical Engineers, the Institute of Electrical and Electronics Engineers, and the American Institute for Medical and Biological Engineering. At Rice, she has been recognized with Rice’s Presidential Award for Mentoring, the Graduate Student Association Faculty Teaching and Mentoring Award, and the Rice University Faculty Award for Excellence in Research, Teaching, and Service.

lessOn the Design and Manufacture of Structures for Flightworthy Gas Turbines
by Apostolos Karafillis
Chief Consulting Engineer
Structures and Additive Design
GE Aerospace
Abstract
The design and manufacture of gas turbine components presents unique technical challenges that highlight the relevance and importance of the disciplines of mechanical and aerospace engineering. In this presentation, we will focus on describing the fundamental technical requirements for parts of flightworthy gas turbines and will then share examples of designs and innovations to meet these requirements. The talk will include the description of typical loading conditions and operating environments, and the description of how these requirements guide the selection of design features, materials, and manufacturing methods. We will discuss three specific examples: The selection of features and architecture of a bearing housing, the design of a turbine frame with a mix of metallic and composite materials, and the development of methods for characterizing the performance of components manufactured with non-traditional methods. Through these examples, it will be shown that successful hardware design requires the combination of robust design methods, rigorous implementation of the principles of mechanics of materials, and the development of design and manufacturing innovation.TIME Tuesday, April 30, 2024 at 2:00 PM - 3:00 PM

Speaker: Russ Tedrake, Toyota Professor of EECS, Aero/Astro, ME at Massachusetts Institute of Technology and VP of Research at Toyota Research Institute
Title: Dexterous Manipulation with Diffusion Policies

Abstract:
At the Toyota Research Institute (TRI), we've been working on behavior cloning for dexterous manipulation. Building on the Diffusion Policy framework that we've recently developed in collaboration with Shuran Song, we now have a very solid pipeline for taking ~50-100 bimanual haptic teleop demonstrations and turning that into a surprisingly effective visuomotor (+tactile) policy. Because there is no explicit state representation required, these skills work equally well manipulating deformable, liquid, or other difficult to model tasks as they do for more traditional rigid-object manipulation. We're actively scaling this up into the multi-task setting and now see a plausible path towards "Large Behavior Models". This behavior cloning pipeline is working incredibly well, and must be understood deeply in the broader context of output-feedback control. Time permitting, I'll also tell you a bit about some new results in optimization-based planning and control, and where they might fit in the age of foundation models.
