A sonar-based mapping and navigation system developed for an autonomous mobile robot operating in unknown and unstructured environments is described. The system uses sonar range data to build a multileveled description of the robot’s surroundings. Sonar readings are interpreted using probability profiles to determine empty and occupied areas.

There exists an immense potential for the utilization of robotic airships as low speed, low altitude aerial vehicles in exploration, monitoring, and transportation tasks. This paper discusses Project AURORA' Autonomous Unmanned Remote monitoring Robotic Airship -, which focuses on the development of the control, navigation, sensing, and inference(More)
We are developing a Sensor Web-relevant system called the Telesupervised Adaptive Ocean Sensor Fleet that uses a group of National Oceanic and Atmospheric Administration extended-deployment autonomous surface vehicles to enable in-situ study of surface and sub-surface characteristics of Harmful Algal Blooms (HAB). The architecture supports adaptive(More)
