140 MINT letter sorting episodes recorded with EvoMind on September 10–11 and September 17, 2026 (UTC+8), combining two previously cleaned datasets.
LeRobot v3.0; bipiperxfollower; 30 FPS; 149,961 frames; 4,998.7 seconds (83 minutes 18.7 seconds). Three original 640x480 RGB camera views: leftwrist, rightwrist, rightenvironment1. Action and observation.state each contain 14 values.
Sources and episode order
The first source retains its historical 73ep repository name but currently contains 70 cleaned episodes. The older uncleaned 73-episode server copy was not used.
Processing and validation
Both sources already underwent synchronized leading-static trimming. This merge performs no additional trimming, retiming, resizing or video encoding. Video files are preserved byte for byte. Every retained action, state, frame index and episode-local timestamp is unchanged. Episode/global indices are regenerated; task indices are remapped while preserving the original task text, including capitalization differences. Per-episode and global numeric statistics are recomputed, and camera statistics are aggregated from the source episode statistics.
All 140 episode mappings and all 420 videos were checked. Video dimensions, FPS, frame availability and timestamps were verified with ffprobe. Action/state and other unchanged table columns were compared exactly against their source episodes. File SHA-256 hashes and validation results are in VALIDATION_RECEIPT.json; source revisions and episode mappings are in provenance.json. Original source cards, cleaning manifests and available validation receipts are preserved under provenance/source-0 and provenance/source-1.
The generic Hugging Face Dataset Viewer is explicitly configured to read only data/chunk-/.parquet, excluding episode/task metadata tables. This table preview is separate from synchronized robot video visualization, and availability depends on Hugging Face's processing service.
