# PAM19
PAM19 is a real-world Franka Panda tactile-manipulation dataset containing
1,904 trajectories across 19 tasks. Demonstrations were collected in joint
space with two RGB cameras and two Xense vision-based tactile sensors, then
converted to FTP-1-compatible Zarr format.
The dataset follows the
[Open-X-Tactile](https://open-x-tactile.github.io/) / FTP-1 data convention.
## Dataset summary
- Robot: Franka Panda with a parallel gripper
- Tactile sensor: Xense, two gripper-side image streams
- RGB streams: main camera and wrist camera
- Tasks: 19
- Trajectories: 1,904
- Frames: 2,061,059
- Control/state representation: 7 arm joints and one gripper-opening scalar
- Image resolution in Zarr: 224 × 224
## Tasks
- `USB_plug`
- `cable_routing`
- `cut`
- `cut_long`
- `drop`
- `erase`

- `tiny_pickB`
## Files
Each task directory contains one store-only split ZIP archive of an
FTP-1-compatible `<task>.zarr` directory. The split size is 10 GiB. Small
tasks may contain only a `.zip` file; larger tasks also contain `.z01`,
`.z02`, and subsequent parts.
To reconstruct and extract a split archive:
```bash
zip -s 0 <task>/<task>.zip --out <task>/<task>-full.zip
unzip <task>/<task>-full.zip
```
## Main Zarr fields
- `timestamps`
- `camera_main_rgb`
- `right_wrist_camera_rgb`
- `right_arm_joints`
- `right_hand_joints`
- `right_hand_joints_idx`
- `right_tactile_data_gripper`
- `right_tactile_area_gripper`
- `right_tactile_sensor_gripper`
- `right_tactile_type_gripper`
- `sub_task_instruction`
The gripper scalar uses canonical hand slot 28. The two tactile channels are
stored in left/right order with functional-area indices `[0, 1]`.
