The Quadroar is composed of an $\\texttt{I}$-shaped frame whose body link is a simple linear actuator, and four disks that can rotate about the axes of flange links. The time symmetry is broken by a combination of disk rotations and the one-dimensional expansion/contraction of the body link. The Quadroar propels on forward and transverse straight lines and performs full three dimensional reorientation maneuvers, which enable","authors_text":"Mir Abbas Jalali, Mohammad-Reza Alam, SeyyedHossein Mousavi","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2014-08-22T21:10:57Z","title":"Versatile low-Reynolds-number swimmer with three-dimensional maneuverability"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1408.5428","kind":"arxiv","version":2},"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":"sha256:12dbb8874fc382afd607d37fa9596033d942a4bd4ccd5f2db700a5fb821e02f6","target":"record","created_at":"2026-05-18T01:42:13Z","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":"23d0daf365d4dac2345d1daa192e1f78b3213190716072427424faec39cebfa0","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2014-08-22T21:10:57Z","title_canon_sha256":"531f0f1d16824541a3b8e7f9d2d1bd19ab85812caece1fd02e4efd052775bd27"},"schema_version":"1.0","source":{"id":"1408.5428","kind":"arxiv","version":2}},"canonical_sha256":"0dc2bd4d8087d9310cbb17763b9e72aa3e53d71d55a68f08f3c2a42109037c7f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0dc2bd4d8087d9310cbb17763b9e72aa3e53d71d55a68f08f3c2a42109037c7f","first_computed_at":"2026-05-18T01:42:13.773033Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:42:13.773033Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JvRA7ebDjclNF7YeU37q/Hzp945IeoTIeiD4AykqUu2DEU1wwVIOcHoObKQw54gbCSr4hT3IqKJIxwhVQ8hNCg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:42:13.773807Z","signed_message":"canonical_sha256_bytes"},"source_id":"1408.5428","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:12dbb8874fc382afd607d37fa9596033d942a4bd4ccd5f2db700a5fb821e02f6","sha256:e18b2a2688058b487f1c9e8ced3ecc5cec177d27a1ea4490dd7b3eafa3c3ef0f"],"state_sha256":"66f8fd5c6c1f298d4689c39b880bfe01f7ea4a36542f6d642dead563e104f2fb"}
