In circumstances where only acoustic signals can be obtained, estimating the geometry of a room is a challenging proposition. Existing methods have been proposed to reconstruct a room from the room impulse responses (RIRs). However, the sound source and microphones must be deployed in a feasible region of the room for it to work, which is impractical when the room is unknown. This work propose to employ a robot equipped with a sound source and four acous","authors_text":"Jaime Valls Miro, Linh Nguyen, Xiaojun Qiu","cross_cats":["cs.RO","eess.AS","eess.SP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SD","submitted_at":"2019-07-02T05:08:27Z","title":"Can a Robot Hear the Shape and Dimensions of a Room?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1907.01169","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:bd2ebea3d1f1d7a576c0017fce6e381bb70142b9cb39641333b07f74b4975781","target":"record","created_at":"2026-05-17T23:41:41Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"46e96cf4ff4f57d0844f40c9ede34a4d562374846afd33f0281939ab93fbe1d2","cross_cats_sorted":["cs.RO","eess.AS","eess.SP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SD","submitted_at":"2019-07-02T05:08:27Z","title_canon_sha256":"de207cd3b53d4d6cf17cc037cf23cd30cd8176209aabad566f6a3468469c94a2"},"schema_version":"1.0","source":{"id":"1907.01169","kind":"arxiv","version":1}},"canonical_sha256":"04a845a4d1e4f16cf87409d0283a7ee9b061e505a00ad051198cc775564274c2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"04a845a4d1e4f16cf87409d0283a7ee9b061e505a00ad051198cc775564274c2","first_computed_at":"2026-05-17T23:41:41.096001Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:41:41.096001Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IsYdTY8IcMCTaY3yKTkPSWgvBn7skXzHxpG6jPD2r+/t0LfN/t4Oi2Gb/ZhG3dJFupWROUxWA1CKlsQWxGM7CQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:41:41.096686Z","signed_message":"canonical_sha256_bytes"},"source_id":"1907.01169","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bd2ebea3d1f1d7a576c0017fce6e381bb70142b9cb39641333b07f74b4975781","sha256:137756089ae3b8bb3df4ab31d7787b8824aea35685bae099566aefe3b89de1a5"],"state_sha256":"4bc1cbaed3cdc6012c40bb2af765759bd27de0d6b96c2863215edf9ace69361f"}
