Object search in realistic large environments is a crucial step for various mobile robot missions. We describe our spatial representation which grounds human-level spatial concepts in lower level representations for efficient informed object search and exploration. We present a principled planning approach to the visual search problem. Finally we perform real world experiments, in a larger and more complex environment than found in previous work.} }
