InternData-A1

Teaser Image

InternData-A1 is a hybrid synthetic-real manipulation dataset containing over 630k trajectories and 7,433 hours across 4 embodiments, 18 skills, 70 tasks, and 227 scenes, covering rigid, articulated, deformable, and fluid-object manipulation.

📢 News

  • Supplementary information: We have supplemented the updated dataset with camera intrinsics, extrinsics, end-effector poses, and TCP poses. For lerobot v2.1, the directory is sim_updated. For lerobot v3.0, the directory is sim_updated_lerobotv30.

🔑 Key Features

  • Heterogeneous multi-robot platforms: ARX Lift-2, AgileX Split Aloha, A2D, Franka
  • Hybrid synthetic-real manipulation demonstrations with task-level digital twins, containing four task categories:
    • Articulation tasks
    • Basic tasks
    • Long-horizon tasks
    • Pick and place tasks
  • Diverse scenarios include:
    • Moving Object Manipulation in Conveyor Belt Scenarios
    • Rigid, articulated, deformable, and fluid-object manipulation
    • Multi-robot / multi-arm collaboration
    • Human-robot interaction
