Abstract: This project is conceiving and constructing a wireless network of embedded devices, for monitoring the behavior of animals in the wild, that will be deployed and tested in a biologically-­‐relevant application.

Abstract: No robots at the sub-­‐cm3 scale exist because their development faces a number of open challenges. This project focuses on identifying and determining means for solving these challenges.

Abstract: We wish to create office divider/façade systems that can adapt their visual appearance and privacy properties to your working needs, can be rearranged within minutes, and allow you to program them by gestures. For example, a wall could sense outside weather and its occupants’ moods and adapt its color accordingly. Or, a wall could provide its user with privacy by becoming opaque and emitting white noise. Finally, individual elements could open themselves up to let air, noise, and little objects pass between zones.

Abstract: We are designing lane merging systems that assist drivers to maneuver safely. The driver signals his intent to change lanes. The cars communicate and create a safe gap. The driver is notified when it is safe to merge, or when a condition occurs that makes a lane change dangerous.

Abstract: This project is developing methods for human context awareness in smart buildings, aging-in-place, smart authorization, and emergency response. We enable this using inference using radio frequency (RF) sensing networks, in which channel measurements are made by deployed wireless networking devices. In RF sensing networks, the network is the sensor. We are developing methods to learn human context for smart facilities and elder care, including:

Abstract: The CYPRESS (CYber Physical RESiliance and Sustainability) project explores techniques for dependability and resilience in instrumented cyberphysical spaces (ICPS) where physical spaces have been instrumented with “intelligence” through heterogeneous sensing, actuation and communication mechanisms.

Abstract: Wireless sensor-actuator networks (WSAN) are systems consisting of numerous sensing and actuation devices that interact with the environment and coordinate their activities over a wireless communication network. WSANs represent an important class of cyber-physical system (CPS) found in the national power grid and air/traffic networks. This project addresses the issue of resilience in WSANs.

Abstract: Wireless sensor-actuator networks (WSAN) consist of numerous sensing and actuation devices that share information over an ad hoc wireless communication network. WSANs can be used to manage networked systems that distribute goods and services over large spatially distributed domains. Examples of such systems include the national power grid, ground/air traffic networks, and water/gas distribution networks.

Abstract: We are developing a new computational framework and physical platform for modeling, analyzing, and designing dense networks of micro-robotic swarms. The physical platform is based on a bio-hybrid micro-robotic approach, in which bacteria serve as on- board actuators. The micro-robots are controlled through passive (e.g. chemical gradients) and active (e.g. magnetic fields) steering mechanisms. Here, we present the first step towards passive control by characterizing the chemotactic behavior of free- swimming bacteria.

Abstract: The objective of this research is to develop numerical techniques for solving partial differential equations (PDE) that govern information flow in dense wireless networks. Despite the analogy of information flow in these networks to physical phenomena such as thermodynamics and fluid mechanics, many physical and protocol imposed constraints make information flow PDEs unique and different from the observed PDEs in physical phenomena.
