ABSTRACT Driven by both civilian and military applications, such as coordinated surveillance, search and rescue, underwater or space exploration, manipulation in hazardous environments, and rapid emergency response, cooperative actions by teams of robots has emerged as an important research area. However, the coordination strategies for such robot teams are still developed to a great extent by trial-and-error processes. Hence, the strategies cannot guarantee mission success. This award supports fundamental research to provide a provably correct formal design theory of multi-robot systems that guarantees mission success. Furthermore, results from the research can be extended to the design of more general cyber-physical systems (CPSs) consisting of distributed and coordinated subsystems, such as the national power grid, ground/air traffic networks, and manufacturing systems. These CPSs are critical components of the national civil infrastructure that must operate reliably to ensure public safety. The multidisciplinary approach taken will help broaden participation of underrepresented groups in research and positively impact engineering education. Focusing on multi-robot teams, the goal of the research is to build foundations for a provably correct formal design theory for CPSs. This design theory will guarantee a given global performance of multi-robot teams through designing local coordination rules and control laws. The basic idea is to decompose the team mission into individual subtasks such that the design can be reduced to a local synthesis problem for individual robots. Multidisciplinary approaches combining hybrid systems, supervisory control, regular inference and model checking will be utilized to achieve this goal. The developed theory will enable robots in the team to cooperatively learn their individual roles in a mission, and then automatically synthesize local supervisors to fulfill their subtasks. A salient feature of this method lies on its ability to handle environmental uncertainties and unmodeled dynamics, as there is no need for an explicit model of the transition dynamics of each agent/robot and their interactions with the environment. In addition, the design is online and reactive, enabling the robot team to adapt to changing environments and dynamic tasking. The derived theory will be implemented as software tools and will be demonstrated through real robotic systems consisting of unmanned ground and aerial vehicles in unstructured urban/rural areas.
Researchers at the University of Notre Dame have designed a simple, yet highly accurate traffic prediction model for roadway transportation networks. They have recently published their work in the journal Nature Communications.
A new study by researchers from the University of Notre Dame and Tsinghua University offers great potential for understanding the social principles that underpin the highly connected world, from individuals to groups to societies.
The award, which was established in 2010, recognizes an outstanding young scientist or engineer under the age of 40 who has contributed to the advancement of theory, technologies, and applications of computational intelligence through inventions, new technologies, innovative technical developments, new product implementations, or the management of innovative product design or production processes.
Notre Dame senior Margaret Pickard understands the challenges of integrating into a culture different from her own. The sociology and Japanese double major studied abroad last year in Nagoya, Japan, where she gained a fresh perspective on the difficulties of being a college student in a foreign setting.

“What if my prescription when I left the physician’s office would just say … ‘I know you live in a neighborhood where you may not have any access to [healthy fruits and vegetables]. Let me incentivize you. Go have a 50 percent discount on the fresh fruits and vegetables you may buy from the grocery store. That may help you?’” Chawla said. Tracking personal data on a large scale could revolutionize the health care industry and improve Americans’ overall well being, he said. “You can be empowered to take the right action,” Chawla said.
