ESE Spring Colloquium – “Bridging Safety and Learning in Human-Robot Interaction”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

From autonomous cars in cities to mobile manipulators at home, robots must interact with people. What makes this hard is that human behavior—especially when interacting with other agents—is vastly complex, varying between individuals, environments, and over time. Thus, robots rely on data and machine learning throughout the design process and during deployment to build and […]

Spring 2022 GRASP SFI: Ted Xiao, Robotics at Google, “A Panorama of End-to-end Robot Learning”

Levine 512

In recent years, a variety of approaches to robotic control have gained popularity as robots play an increasingly larger role in our everyday lives. In this talk I will give an introduction to modern-day robot learning, covering engineering and research challenges. After establishing the foundations of popular methods, I will present why I believe that end-to-end […]

CBE Seminar: “Spying on Sugar Transporters: Kinetic Studies of Biomolecular Sensors”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Abstract The allocation of sugars from photosynthetic leaves to storage tissues in seeds, fruits, and tubers is an essential determinant of crop yields. In plants, transporters play critical roles in allocating carbon to different organs. Transgenic modifications of plant membrane transporters have been shown to enhance crop yield and increase plants' resistance to biotic and […]

ESE Spring Seminar – “Learning to Interact With the World: When Generality Meets Precision”

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Robotics stands as one of the most impactful and promising endeavors of our times. Learning to interact with the world is fundamental for solving some of our most pressing societal challenges: from taking care of our aging population and aiding with labor-intensive jobs to assisting in climate-related disasters and rescue emergencies. In this talk, I […]

GRASP on Robotics: Shai Revzen, University of Michigan, Ann Arbor, “Multi-legged slipping is simpler than you think”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

 Multi-contact sliding mechanics in general and multilegged slipping in particular have long been considered difficult to model.  As a consequence roboticists have avoided building multilegged systems and designing motion plans which include intentional slipping.  I present a series of experiments and mathematical advances that demonstrate how these problems become easier with more contacts.  These advances […]

PICS Colloquium: “Mechanics of Polymeric Gels”

PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United States

This talk discusses recent and ongoing research on the multiphysics response of polymeric gels. A polymeric gel is a polymeric material swollen by a fluid, and the intake or out-flow causes large deformations. Also, many gels respond to environmental stimuli such as temperature, electric and magnetic fields, pH, and more. The responsiveness of polymeric gels […]
