Distributed Source Seeking Without Global Position Information

Open Source Programmers’ Information Seeking

Source seeking with non-holonomic unicycle without position measurement and with tuning of forward velocity

We consider the problem of seeking the source of a scalar signal using an autonomous vehicle modeled as the non-holonomic unicycle and equipped with a sensor of that scalar signal but not possessing the capability to sense either the position of the source nor its own position. We assume that the signal field is the strongest at the source and decays away from it. The functional form of the fie...

Unspoofable Source Identifiers without Global Trust

Distributed Algorithms for Stochastic Source Seeking With Mobile Robot Networks

Autonomous robot networks are an effective tool for monitoring large-scale environmental fields. This paper proposes distributed control strategies for localizing the source of a noisy signal, which could represent a physical quantity of interest such as magnetic force, heat, radio signal, or chemical concentration. We develop algorithms specific to two scenarios: one in which the sensors have ...

Studying Team Cognition during Collaborative Information Seeking: A Position Paper

Team cognition concepts are important in the collaborative information seeking (CIS) community. Yet, while this importance has been recognized there is a lack of research on team cognition within CIS. We take the position that team cognition concepts and measurements can be very useful to CIS researchers . This paper provides an understanding of what team mental models and common ground are. We...
