Information-Driven Gas Distribution Mapping for Autonomous Mobile Robots.
Góngora González, Andrés; González-Monroy, Javier; Rahbar, Faezeh; Ercolani, Chiara; González-Jiménez, Antonio Javier; Martinoli, Alcherio[et al.] (MDPI, 2023-06-07)The ability to sense airborne pollutants with mobile robots provides a valuable asset for domains such as industrial safety and environmental monitoring. Oftentimes, this involves detecting how certain gases are spread out ... -
Information-Driven Gas Source Localization Exploiting Gas and Wind Local Measurements for Autonomous Mobile Robots
Ojeda, Pepe; González-Monroy, Javier; González-Jiménez, Antonio Javier (IEEE, 2021-04)Gas source localization (GSL) by an olfactory robot is a research field with a great potential for applications but also with numerous unsolved challenges, particularly when the search must take place in realistic, indoor ... -
Initialization of 3D Pose Graph Optimization using Lagrangian duality
Briales Garcia, Jesus; González-Jiménez, Antonio Javier (IEEE, 2017-05)Pose Graph Optimization (PGO) is the de facto choice to solve the trajectory of an agent in Simultaneous Localization and Mapping (SLAM). The Maximum Likelihood Estimation (MLE) for PGO is a non-convex problem for which ... -
