Multi-robot coordination and cooperation are critical behaviors that improve team performance and enable new tasks in application areas like autonomous construction, agriculture, and extended operation in large unknown regions. This talk explores the utility of graph-based modeling and computational frameworks to improve the coordination and cooperation of multi-robot teams in a variety of problems. I […]
A modular self-reconfigurable robot (MSRR) is a set of robotic building blocks that can be connected together in different ways. By rearranging these connections, the robot can adapt its shape to address a wider variety of tasks than a robot with a fixed morphology. However, traditional modular architectures fail to scale up to address large-scale […]
Engineers in modern society are taught to design and build structures and robots from pre-processed materials, giving them the ability to describe the operating capacity of their structure with a high degree of certainty. From a disaster recovery and robust systems point of view, this is a severe limitation. Rather than use processed material of […]
Non-equilibrium phenomena are ubiquitous across material systems and of great technological relevance. Examples of such phenomena include diffusion processes in liquid and gases, viscoelasticity and plasticity in solids, and rheological behavior of colloidal and granular media. Despite their ubiquity and importance, the understanding of non-equilibrium phenomena remains in its infancy compared with classical equilibrium thermodynamics […]
Traditional approaches for active mapping focus on building geometric maps. For most real-world applications, however, actionable information is related to semantically meaningful objects in the environment. We propose an approach to the active metric-semantic mapping problem that enables multiple heterogeneous robots to collaboratively build a map of the environment. The robots actively explore to minimize […]

Microorganisms, primitive unicellular forms of life, form the basis of the food web and play crucial roles in the Earth's biogeochemical cycles. Habitats of microorganisms, from oceans and lakes to soil and human intestines, are often characterized by constant fluid motion. Fluid flow exerts forces and torques on microorganisms that affect their movement and distribution, […]
Blood clotting is primarily responsible for stemming bleeding in vessel injury, comprising a protective mechanism called hemostasis. However, if a blood clot forms within a blood vessel when or where it is not needed, this can result in death and disability. Blood clots and thrombi are composed of blood cells embedded into a polymeric fibrin […]
Actuator reduction is especially important for aerial robots, where minimizing mass and conserving power is critical. Bistable mechanisms have been used to augment actuators by speeding up actuation time or allowing one direction of actuation to be passive. In this talk we will explore how bistable mechanisms can reduce the number of actuators needed in […]
There is currently a critical need for blood donors, and members of the Penn Engineering community are invited to participate in a school-wide blood drive. To join in this effort, please RSVP using this link.
Structural design optimization has long played a crucial role in engineering, often with the goal of creating stiff and lightweight structures for aerospace and other applications. However, optimizing structures against failure is also crucial and has been much less well explored. Failure via fracture and at interfaces is particularly challenging in design optimization as they […]
