Two stereo vision-based mobile robots navigate and autonomously explore their environment safely while building occupancy grid maps of the environment. A novel landmark recognitio...
Abstract— A location tracking sensor network is being deployed in several buildings at the University of Michigan to help explore issues in design of pervasive environments. Mana...
We explore fundamental performance limits of tracking a target in a two-dimensional field of binary proximity sensors, and design algorithms that attain those limits. In particul...
The availability of positional information is of great importance in many commercial, governmental, and military applications. Localization is commonly accomplished through the use...
We consider the problem of providing network access to hosts whose physical location changes with time. Such hosts cannot depend on traditional forms of network connectivity and r...
