+# HeteroTask assets
+
+Assets of the heterogeneous vision-language-action pick-and-place tasks of Isaac Lab
+(`isaaclab_tasks.contrib.heterogeneous_tasks`, registered as `IsaacContrib-VLA-PickPlace<NNN>-Franka` and
+`IsaacContrib-VLA-Heterogeneous-Franka`), as complete USD files. The tasks load them from
+`https://huggingface.co/datasets/LiFanxing/HeteroTask/resolve/main`, or from the location in the
+`VLA_BENCHMARKS_ASSETS_DIR` environment variable.
+
+## Layout
+
+| Path | Content |
+|---|---|
+| `objects/<name>/<name>.usd` | An object or piece of furniture with its physics: rigid body, mass and inertia, and convex-hull colliders (objects) or box colliders (furniture). |
+| `objects/<name>/materials/` | The textures and MDL materials of the object. |
+| `robots/franka_robotiq_2f_85/` | Franka arm with a Robotiq 2F-85 gripper. |
+| `scene/franka_table/` | Table that the robot stands on. |
+| `scene/home_office.exr` | Dome light texture. |
+
+## Sources
+
+- Objects and furniture: the [Omniverse](https://omniverse-content-production.s3-us-west-2.amazonaws.com/Assets/)
+  SimReady and ArchVis libraries, and the RoboLab object library (YCB, HOPE, HOT3D, HANDAL, Objaverse and other
+  objects). The ArchVis models, which have no physics, got rigid bodies, masses and colliders; colliders decomposed
+  into convex hulls were baked into at most 32 hulls each (16 for ArchVis objects), and furniture collides with boxes
+  of its boards and panels.
+- Robot, robot table and dome light texture: RoboLab.
+
+The assets keep the licenses of their sources.
