Guiding navigation of unknown environments with distant visual cues
While navigating unknown environments, robots rely primarily on proximate features for guidance in decision making such as depth information from lidar or stereo to build a costmap, or local semantic information from images. The limited range over which these features can be used can result in poor …

Generating informative paths for persistent sensing in unknown environments
… to locally optimal configurations for sensing an unknown dynamical environment. As the robots travels through their paths, they identify the areas where the environment is dynamic and shape their paths to sense these areas. A Lyapunov-like stability proof is used to show that, under the proposed …
