A finger-shaped sensor based on fibre-optics is employed for the data acquisition to collect data for the analysis and the experiments. To detect the possible locations of cracks a camera is used to scan an environment while running an object detection algorithm. Once the crack is detected, a fully-connected graph is created from a skeletonised version of the crack. A minimum spanning tree is then employed for calculating the shortest path to explore the crack which","authors_text":"Bukeikhan Omarali, Changae Oh, Francesca Palermo, Ildar Farkhatdinov, Kaspar Althoefer","cross_cats":["cs.CV","cs.LG"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.RO","submitted_at":"2023-07-13T14:50:38Z","title":"Robotic surface exploration with vision and tactile sensing for cracks detection and characterisation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2307.06784","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":"sha256:70f469263b0e3f8350f1ba651565fea854fa8b400e0a130464e58feeb0fc6920","target":"record","created_at":"2026-07-05T06:30:37Z","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":"50ba040b11b4ac7cb4dc9f63bcf609c080c3ffe70dcf65d25c7af2ceb4efe002","cross_cats_sorted":["cs.CV","cs.LG"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.RO","submitted_at":"2023-07-13T14:50:38Z","title_canon_sha256":"12087ed1d7402f082289260838173d415aaa6a7d3c1e99e54271e39c54b1f465"},"schema_version":"1.0","source":{"id":"2307.06784","kind":"arxiv","version":1}},"canonical_sha256":"13a5f2833c47997e0898eb7c67acfe0f919bc784d55561be26c19f215351c47f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"13a5f2833c47997e0898eb7c67acfe0f919bc784d55561be26c19f215351c47f","first_computed_at":"2026-07-05T06:30:37.578390Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:30:37.578390Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"UIkz5+CLmy7z2btuLNLBBIwLNYGmCI9qK8g/ynUhm6anknNFzqL+mh30VZS/aYmnBiuxoNwQ6FOxz7BxyciIDg==","signature_status":"signed_v1","signed_at":"2026-07-05T06:30:37.578912Z","signed_message":"canonical_sha256_bytes"},"source_id":"2307.06784","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:70f469263b0e3f8350f1ba651565fea854fa8b400e0a130464e58feeb0fc6920","sha256:c199424141e5493d8d79f986ea24e7c44d54e94a0f7254632a161251d8e08d18"],"state_sha256":"ed6703acb313fad53c1274ec5b3fb312a5f6de77b46bee4fb6af0d3b9913d798"}
