Abstract We study routing and searching decisions of a search-and-detection (SDT) team on road network under online uncertainty setting. Given an undirected edge-weighted bounded graph, static target is positioned at unknown vertex among potential vertices in the graph. A non-negative search cost given each vertices. The detected once SDT searches its corresponding vertex. There may be some non...

We discuss online strategies for visibility-based searching for an object hidden behind a corner, using Kurt3D, a real autonomous mobile robot. This task is closely related to a number of well-studied problems. Our robot uses a three-dimensional laser scanner in a stop, scan, plan, go fashion for building a virtual three-dimensional environment. Besides planning trajectories and avoiding obstac...
