 # OpenViTac Benchmark Dataset
 
-OpenViTac is a visuo-tactile robot manipulation benchmark covering physical-property perception, fragile-object handling, contact-rich manipulation, and precise insertion. This release contains **1,300 simulated trajectories** in HDF5 format across 11 tasks. 
+OpenViTac is a visuo-tactile robot manipulation benchmark covering physical-property perception, fragile-object handling, contact-rich manipulation, and precise insertion. This release contains **1,500 simulated episodes in LeRobot v2.1 format** across 11 tasks: 1,300 with GelSight mini and 100 each with Neote and Xense for `insert_USB`.
 
 For the benchmark and data-collection details, see the [paper](https://arxiv.org/abs/2610.10384v1) and [code repository](https://github.com/FVL-Repo/OpenViTac).
 
 ## Simulation tasks
 
-Each task is stored under `Simulation/GelSight_mini/<task>/`. Some tasks have subdirectories for object properties or variants.
+Each `Simulation/<sensor>/<task>/` directory is a separate LeRobot dataset. Its `meta/` directory contains episode metadata, `data/chunk-000/` contains one Parquet file per episode, and `videos/chunk-000/` contains the corresponding camera and tactile videos. GelSight mini data is under `Simulation/GelSight_mini/`.
