| # Dataset Card |
|
|
| This is the fine-tuning dataset used in the paper *RDT-1B: a Diffusion Foundation Model for Bimanual Manipulation*. |

|
| ## Getting Started |
|
|
| Download all archive files and use the following command to extract: |
| ```bash |
| cat rdt_data.tar.gz.* | tar -xzvf - |
| ``` |
|
|
| In the resulting `rdt_data` folder, each sub-folder is a task. In each task sub-folder, we have HDF5 files and the instruction JSON file, as illustrated below: |
| ``` |
| rdt_data/---task_1/---episode_1.hdf5 |
| | | |
| |-task_2/ |-episode_2.hdf5 |
| | | |
| |-task_3/ |-... |
| | | |
| |-... |-expanded_instruction_gpt-4-turbo.json |
| ``` |
| Each HDF5 file corresponds to a trajectory/episode of the task, which has the following keys: |
| - `observations`: |
| - `qpos`: joint positions of the two robot arms, (TRAJ_LEN, 14); the seventh and fourteenth joints are gripper joint angles |
| - `images`: |
| - `cam_high`: RGB images from the exterior camera at each time step, (TRAJ_LEN, 480, 640, 3) |
| - `cam_left_wrist`: RGB images from the left-wrist camera at each time step, (TRAJ_LEN, 480, 640, 3) |
| - `cam_right_wrist`: RGB images from the right-wrist camera at each time step, (TRAJ_LEN, 480, 640, 3) |
| - `action`: desired joint positions of the two robot arms at the next time step, |
| (TRAJ_LEN, 14); Note that this is slightly different from the actual joint positions at the next time step |
|
|
| Note: The number of HDF5 episode files is not necessarily consecutive. `TRAJ_LEN` may vary from episode to episode. |
| |
| Each JSON file corresponds to the annotated language instructions of the task, which has the following keys: |
| - `instruction`: original human-annotated instructions; its value is a string |
| - `expanded_instruction`: instructions generated by GPT-4-Turbo by expanding the original one; its value is a list of strings |
| - `simplified_instruction`: instructions generated by GPT-4-Turbo by simplifying the original one; its value is a list of strings |
