Pictured below are views of Corky, an experimental stairs/rubble climber Retsina agents come with built-in planning, & communications capability and have been designed to support cooperation including dynamic discovery and loss of communications NIST photograph of Orange Arena Individual RETSINA agent architecture Simulated Orange arena (without rubble) Robot level view real arena Typical RETSINA MAS architecture Retsina agents will provide outer loop control and serve to link USAR robots with one another, human controllers, and external information sources. 1               Acknowledgements This project is supported by NSF grant NSF-ITR-0205526..
