+# move_stuff
+
+Converted from the Hugging Face dataset [`ymatari/move-stuff`](https://huggingface.co/datasets/ymatari/move-stuff) to Apache TsFile format.
+
+## Source Dataset
+
+- **Original dataset:** [`ymatari/move-stuff`](https://huggingface.co/datasets/ymatari/move-stuff)
+- **Authors:** ymatari
+- **License:** apache-2.0
+
+## Conversion Notes
+
+- Conversion mode: `script`
+- Time precision: `ms`
+- TsFile data files: `['data/move_stuff.tsfile']`
+- Converter: `scripts/converters/lerobot.py`
+
+## Usage
+
+
+Install the Apache TsFile Python SDK (`pip install tsfile`) and read a converted file:
+
+```python
+from pathlib import Path
+from tsfile import TsFileReader
+
+path = Path("data/move_stuff.tsfile")
+with TsFileReader(str(path)) as reader:
+    schemas = reader.get_all_table_schemas()
+    print("tables:", list(schemas))
+    table_name = next(iter(schemas))
+    table = schemas[table_name]
+    columns = [column.get_column_name() for column in table.get_columns()]
+    print("columns:", columns)
+    field_names = [
+        column.get_column_name()
+        for column in table.get_columns()
+        if column.get_column_name() not in {"Time", "time"}
+    ]
+    if field_names:
+        with reader.query_table(table_name, field_names[:3], batch_size=1024) as result:
+            batch = result.read_arrow_batch()
+            if batch is not None:
+                print(batch.to_pandas().head())
+```
