We study the problem of actively locating a static target using mobile robots equipped with
bearing sensors. The goal is to reduce the uncertainty in the target's location to a value …

Preliminary results on quadrotor control strategies enabling omnidirectional radio frequency
(RF) sensing for source localization and tracking are discussed. The use of a quadrotor for …

We investigate a computationally and memory efficient algorithm for radio frequency (RF)
source-seeking with a single-wing rotating micro aerial vehicle (MAV) equipped with a …

We study the problem of optimally choosing bearing measurement locations for localizing a
stationary target in minimum time. The targets are transmitting radio tags, and bearing …

There are a large class of problems, from search and rescue to environmental monitoring,
that can benefit from teams of mobile robots in environments where there is no existing …

We propose scale-free coordinates as an alternative coordinate system for multi-robot
systems with large robot populations. Scale-free coordinates allow each robot to know, up to …

This paper presents a particle filter design to improve the accuracy of received signal
strength indicator (RSSI)-based localization algorithms for localizing mobile robots that …

We study the problem of minimizing the time to accurately localize a target using radio-
based telemetry. The directional nature of the antenna allows us to obtain bearing-to-target …

A radio source is anything that emits radio signals. It might be a signal jammer, a cellphone,
a wildlife radio-tag, or the telemetry radio of an unauthorized drone. It is often critical to find …

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 …
