The source seeking is a relevant topic on autonomous robotics. In a few words, it consists of seeking a scalar signal source position with only local information on base X-space. In such, the seek agent, for instance, a mobile tracking A-robot, samples by hypothesis C ∞ -class source signal ϕ-map constrained by hull (A) ⊆ X. Among available seeking methods, this work utilizes the barycenter method, first presented on work [2], as a direct optimization method due to derivatives' absence. The applied algorithm estimates the source ŷn -position and designs a suitable reference γ(t)-curve, hopefully towards a sufficiently close vicinity of the actual source y ⋆ s -position. In case there are multiple critical points, the {d(y ⋆ s , ŷn )}-sequence may not converge asymptotically to a sufficiently close neighborhood of zero due to its local behavior, a challenge for these garden-like optimization algorithms. This work succeeds to obtain results in direction of the source signal position. Therefore, the proposed methodology provides an alternative for source-seeking applications by defined-to-be exploration strategy by different agent seekers, source signal maps, and obstacle modeling.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
