PhD’s Thesis Defense, David Julián Saldaña Santacruz

We would like to congratulate David Julián Saldaña Santacruz on the defense of his Thesis at UFMG.

Title: Detecting and predicting environmental boundaries with a team of robots


Environmental boundaries, such as the borderline of a forest fire or an oil spill, pose a significant threat for living organisms. Anticipating the dynamics of these phenomena is a potentially life-saving indicator to support efficient and effective evacuations or to dispel the hazard. We propose a decentralized coordination method that allows multiple robots to efficiently sample and predict the behavior of environmental boundaries. Our method does not require a priori information about the boundary dynamics. We validate our proposal through experiments with actual robots. We show how the accuracy of our estimation method is affected by different factors. We demonstrate experimentally that our method can estimate and predict non-convex boundaries even with noisy measurements and inaccurate actuators.
