We present a new robotic architecture for research in mobile sensor networks and new interactive gaming environments. The RagoWorld consists of a fully capable, modular mobile platform and an interactive gaming environment, replete with a diverse array of navigational hazards, sensing obstacles, and detectable objects. Currently, Ragobot, the robotic platform, is capable of traversing complex terrains, avoiding moderately sized objects, and reading and writing RFID tags. The next generation of Ragobots will support multiple different sensor node architectures and have more sensing modalities, such as inertial navigation and acoustic tracking.
