Gambardella, Luca Maria Giusti, Alessandro Guzzi, Jérôme 2018-06-27 Autonomous robots in real-world environments face a number of challenges even to accomplish apparently simple tasks like moving to a given location. We present four realistic scenarios in which robot navigation takes into account partial information, hierarchical structures, and multiple objectives. We start by discussing navigation in indoor environments shared with people, where routes are characterized by effort, risk, and social impact. Next, we improve navigation by computing optimal trajectories and implementing human-friendly local navigation behaviors. Finally, we move to outdoor environments, where robots rely on uncertain traversability estimations and need to account for the risk of getting stuck or having to change route. application/pdf https://susi.usi.ch/global/documents/318839 https://localhost:5000/ark:/12658/srd1318839 https://susi.usi.ch/documents/318839/files/2018INFO010.pdf eng info:eu-repo/semantics/altIdentifier/urn/urn:nbn:ch:rero-006-117622 info:eu-repo/semantics/altIdentifier/ark/12658/srd1318839 info:eu-repo/semantics/openAccess License undefined Path planning Navigation Mobile robots info:eu-repo/classification/udc/004 Path planning for mobile robots in the real world : handling multiple objectives, hierarchical structures and partial information http://purl.org/coar/resource_type/c_db06
