We present an adaptive human-robot collaborative workflow for masonry construction that addresses communication limitations and tolerance accumulation, demonstrated through a brickwork case study in which a robot places bricks while a human applies adhesive. This workflow is enabled by two complementary mechanisms: 1) an end-effector-mounted projector that provides spatially registered, just-in-ti","authors_text":"Arash Adel (1) ((1) Princeton University), Jutang Gao (1)","cross_cats":["cs.HC"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.RO","submitted_at":"2026-05-18T18:42:31Z","title":"Adaptive Human-Robot Collaboration for Masonry Construction Under Material and Assembly Uncertainty"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.20264","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":"sha256:11f5ba523c63fb32048fd632f03808edc84156db3edf7ecd32758a058b8dbecb","target":"record","created_at":"2026-05-21T00:04:23Z","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":"4d0a9d6c83bf73fa569198fb595a1e79c9d67bae498d212ad0365a47a2347718","cross_cats_sorted":["cs.HC"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.RO","submitted_at":"2026-05-18T18:42:31Z","title_canon_sha256":"800f76e8533a6e72da6a960acd98f83eb9c1460468aa40e907128d6cabd09ae2"},"schema_version":"1.0","source":{"id":"2605.20264","kind":"arxiv","version":1}},"canonical_sha256":"ba48178f99298fcfad09debee84c90c2717dd84039cdd9a0298730187a92cf03","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ba48178f99298fcfad09debee84c90c2717dd84039cdd9a0298730187a92cf03","first_computed_at":"2026-05-21T00:04:23.163215Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-21T00:04:23.163215Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"o1ov4eWTK/jrAEA9Ido9VHl3SiphPnj9VNOv9jDZwGgWUE/d0G8tsinGKBlMU0Rk+Rqpae+16NdUNj6wphVoAQ==","signature_status":"signed_v1","signed_at":"2026-05-21T00:04:23.163731Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.20264","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:11f5ba523c63fb32048fd632f03808edc84156db3edf7ecd32758a058b8dbecb","sha256:5961143072b2a90fb1388a5ac351936a4921df5d428bfb67b6b6c298cb4f7d96"],"state_sha256":"3b09535cb2f78a27b1e57c0de7178c5bc0538d483fe56bd54a08a3263f95168a"}
