1. Overview
This dataset is generated in the ManiSkill simulation environment.
It contains two types of data pairs:
Random joint sampling subset
- Randomly sampled robot joint configurations (qpos).
- For each sampled configuration, multi-view RGBD images are rendered.
Trajectory subset
- Full trajectories from ManiSkill's demonstrations (.h5).
- For each time step, one-view RGBD images are rendered.
2. Dataset Structure
On the Hub, the dataset is organized as follows:
surgingTu/robot-maniskill-image-state-dataset-v1
├── pickcube_rgb_traj_v1/
│ └── PickCube-v1/
│ ├── traj_0/
│ ├── traj_1/
│ ├── ...
│ └── traj_K/
└── pickcube_rgb_random_v1/
└── random_robot_rendering/
├── sample_00000/
├── sample_00001/
├── ...
└── sample_NNNNN/
2.1 Trajectory subset
Each trajectory directory (e.g. traj_0) has the structure:
pickcube_rgb_traj_v1/PickCube-v1/traj_0/
├── images/
│ ├── {CAM_NAME}_step0000.png
| ├── {CAM_NAME}_step0000_depth.npy
│ ├── {CAM_NAME}_step0001.png
| ├── {CAM_NAME}_step0001_depth.npy
│ ├── ...
│ ├── {CAM_NAME}_step{T-1:04d}.png
│ └── {CAM_NAME}_step{T-1:04d}_depth.npy
└── actions.npy # shape (T, A), low-level actions per time step
├── qpos.npy # shape (T, D_qpos), joint positions per time step
├── camera_params.json
├── ...
CAM_NAME encodes the camera configuration (e.g. y_angle_0_z_angle_0). *_stepXXXX.png is the image at time step XXXX.
All cameras share the same step index.
2.2 Random joint sampling subset
Each random sample directory (e.g. sample_0000) has the structure:
pickcube_rgb_random_v1/random_robot_rendering/sample_00000/
├── images/
│ ├── {CAM_NAME}.png
| ├── {CAM_NAME}_depth.npy
│ ├── {CAM_NAME}.png
| ├── {CAM_NAME}_depth.npy
│ ├── ...
│ ├── {CAM_NAME}.png
│ └── {CAM_NAME}_depth.npy
└── qpos.npy # shape (1, D_qpos), random joint configurations
├── camera_params.json
