-Sampling is a critical problem in the observation of underwater phenomena using single or multiple AUV platforms. The determination of optimal paths and sampling strategies that effectively utilize available resources is critical to these missions. Recent work performed jointly at RPI and AUSI on the development of Adaptive Sampling Algorithms (ASA) utilizes information measures, estimation theory, and potential fields to direct the robots to the locations in space most likely to yield information about the sensed field variable of interest. Typical sensory information can consist of spatial distribution of one or more field variables, such as salinity, dissolved oxygen, temperature, current, etc. In order to test our algorithms we have created the MATCON simulation environment, an underwater experimental platform using solar AUVs, and a land-based experimental testbed using inexpensive wheeled robots.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
