Dataset Card for TRANSIC Data

This dataset card is accompanied with the CoRL 2024 paper titled TRANSIC: Sim-to-Real Policy Transfer by Learning from Online Correction. It includes generated simulation data and real-robot human correction data for sim-to-real transfer of robotic arm manipulation policies.

Dataset Details

Dataset Description

This dataset includes two parts, 1) simulation data used in student policy distillation and 2) real-robot data used in residual policy learning.

The first part can be found in the distillation folder. We include 5 tasks in the distillation/tasks directory. For each task, we provide 10,000 successful trajectories generated by teacher policies trained with reinforcement learning in simulation. Furthermore, we also provide matched_point_cloud_scenes.h5, a seperate collection of 59 matched point clouds in simulation and the real world. We use them to regularize the point-cloud encoder during policy training.

The second part can be found in the correction_data folder. We include real-world human correction data for 5 tasks. Each task contains different number of trajectories. Each trajectory includes observations, pre-intervention actions, and post-intervention actions for residual policy learning.

Dataset Creation

distillation/tasks/*.hdf5 are generated by teacher policies trained with reinforcement learning in simulation. distillation/matched_point_cloud_scenes.h5 and correction_data/*/*.hdf5 are manually collected in the real world.
