In this work, we develop a flexible and cost-effective approach to address this gap by introducing a vision-based system for liquid volume estimation and a simulation-driven pouring method particularly designed for containers with small openings. We evaluate both components individually, followed by an applied real-world integration of cell culture automation using a UR5 ","authors_text":"Daniel Schober, James Love, Lazaros Nalpantidis, Ronja G\\\"uldenring","cross_cats":["cs.CV"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.RO","submitted_at":"2024-04-25T11:42:32Z","title":"Vision-based robot manipulation of transparent liquid containers in a laboratory setting"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2404.16529","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:a1de0fc5d8afd0be7a88a1f4a550f2f442415f3fc30f2462c1d6e3ef64558124","target":"record","created_at":"2026-07-05T09:25:24Z","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":"3dc3df1319bfcd2d6a7d3c5e9ce6259b71c6a5ac249fd882933ae9c4f991652f","cross_cats_sorted":["cs.CV"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.RO","submitted_at":"2024-04-25T11:42:32Z","title_canon_sha256":"215ef0e63033c1e6d2ead0d653d205b39c73bb22db164b596f52ebab92ab7ba1"},"schema_version":"1.0","source":{"id":"2404.16529","kind":"arxiv","version":1}},"canonical_sha256":"94b6e2d4da07f2dc8ffe7693f932916015a07571cbac0d850ebe011812aecac3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"94b6e2d4da07f2dc8ffe7693f932916015a07571cbac0d850ebe011812aecac3","first_computed_at":"2026-07-05T09:25:24.064719Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:25:24.064719Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PyT7kf9VvQ2YNIfoHyw+lz9162Fjm610xTcX0NtsFaYs1lNabkhzTm32yHzkhk8psB7lJe+D+5yYdWw/bxNvDw==","signature_status":"signed_v1","signed_at":"2026-07-05T09:25:24.065154Z","signed_message":"canonical_sha256_bytes"},"source_id":"2404.16529","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a1de0fc5d8afd0be7a88a1f4a550f2f442415f3fc30f2462c1d6e3ef64558124","sha256:339a817d4f1ad922121164da185a0c98c123c7efb3fddd1228a6dfa7e6b33e6a"],"state_sha256":"bf61e63e877bf0741d88a37e09e85a833ec3320390cf32faaad1b9b7c3b684e9"}
