# ArticuBot Simulated Dataset for Trajectories of Articulation (saved in WebDataset Format and splitter into train / val)
## Data Format
Each sample in the WebDataset contains:
- `metadata.json`: Complete metadata including object_id, category, and trajectory info
- `trajectory.pkl`: Trajectory data with all timesteps
- `info.json`: Sample structure information
## Sample Structure
Each trajectory contains timesteps with the following data:
- `state`: Robot state information
- `action`: Robot actions
- `point_cloud`: Scene point cloud
- `gripper_pcd`: Gripper point cloud
- `displacement_gripper_to_object`: Spatial displacement vectors
- `goal_gripper_pcd`: Goal gripper point cloud
