first_humanoid_dataset

Converted Apache TsFile version of skyzos/first-humanoid-dataset, a LeRobot v2.1 humanoid manipulation dataset.

Source Dataset

• Original dataset: skyzos/first-humanoid-dataset
• License: apache-2.0
• Task: pick the block with the right arm and put it in the middle, then use the left arm and put it in the middle.
• Source split: train
• Source scale from meta/info.json: 19 episodes, 2,285 frames, 1 task, 57 videos, 30 fps
• Robot type: not specified in the source meta/info.json
• Modalities: Time-series. The source repository also contains videos, but this converted repository stores only numeric robot state/action time-series data and metadata.

TsFile Layout

• Data file: data/first_humanoid_dataset.tsfile
• Table name: first_humanoid_dataset
• Rows: 2,285
• Time precision: milliseconds
• TAG columns: episode_index, task_index
• FIELD columns: frame_index, sample_index, observation_state_0 through observation_state_31, and action_0 through action_13

The converted table uses the original LeRobot episode_index and task_index columns as TsFile TAG columns. Query one episode by filtering on episode_index.

Conversion Notes

• Converted with the generic lerobot converter in the huggingface_to_tsfile pipeline.
• Time = round(timestamp * 1000) in milliseconds and restarts per episode.
• The source timestamp column is not retained as a separate FIELD because it is redundant with Time / 1000.
• The source index column is renamed to sample_index.
• Vector columns are flattened while preserving the full source column name with . replaced by _: observation.state[32] becomes observation_state_0..observation_state_31, and action[14] becomes action_0..action_13.
• Numeric arrays are stored as single-precision FLOAT fields.
• Source videos are not uploaded here. They remain in the original dataset under videos/.
• The source repository also contains unrelated nvim-linux-x86_64/ files; those files are intentionally excluded from this time-series conversion.
• meta/ is mirrored from the source except that meta/info.json describes the converted TsFile artifact and records the original video path separately.
