We develop algorithms for estimation and control that allow a team of robots equipped with
range sensors to localize an unknown target in a known but complex environment. We …

We consider the combined problem of frontier exploration in a complex indoor environment
while seeking a radio source. To do this in an efficient manner, we incorporate radio signal …

Multi-robot teams that intelligently gather information have the potential to transform
industries as diverse as agriculture, space exploration, mining, environmental monitoring …

We consider the problem of drawing a mobile platform such as an Unmanned Aerial Vehicle
(UAV) to a radio frequency (RF) source surrounded by local scatterers. The UAV starts from …

In tunnel-like environments such as road tunnels or mines, a team of networked mobile
robots can provide surveillance, search and rescue, or monitoring services. However, these …

A robot is sometimes unable to obtain its precise location, or the location of its neighbors,
due to the limitations of the global positioning system (GPS) or due to positioning information …

Precision-guided airdrop systems have shown considerable accuracy improvements over
more widely used unguided systems through high-quality position, velocity, and time …

Radio Frequency transmitters are becoming ubiquitous. For instance people oftencarry
around a mobile phone containing several such transmitters. Having theability to detect and …

Wireless networking is challenging in safety, security, and rescue contexts where network
infrastructure may be damaged or compromised. Radio communication between ground …

Finding the physical location of a specific network node is a prototypical task for navigation
inside a wireless network. In this paper, we consider in depth the implications of wireless …
