# RoboTwin 2.0
-RoboTwin 2.0 is a **large-scale dual-arm manipulation benchmark** built on the SAPIEN physics engine. It provides a standardized evaluation protocol for bimanual robotic policies across 60 tasks with strong domain randomization (clutter, lighting, background, tabletop height, and language instructions).
+RoboTwin 2.0 is a **large-scale dual-arm manipulation benchmark** built on the SAPIEN physics engine. It provides a standardized evaluation protocol for bimanual robotic policies across 50 tasks (as of upstream `main`) with strong domain randomization (clutter, lighting, background, tabletop height, and language instructions).

+RoboTwin 2.0 ships 50 dual-arm manipulation tasks in its upstream `envs/` directory. The canonical list is the `ROBOTWIN_TASKS` tuple in `src/lerobot/envs/robotwin.py`, mirrored verbatim from the upstream repo. Example tasks:
-| Task | CLI name | Category |
-| ---------------------- | ------------------------ | ---------------- |
-| Beat block with hammer | `beat_block_hammer` | Tool use |
-| Open / close laptop | `open_laptop` | Articulated obj |

-| Pour water | `pour_water` | Deformable/fluid |
-| Fold cloth | `fold_cloth` | Deformable |

+| ------------------------ | ------------------------ | ----------------- |
+| Beat block with hammer | `beat_block_hammer` | Tool use |
+| Click bell / alarm clock | `click_bell` | Precision press |
+| Stack blocks (2 / 3) | `stack_blocks_two/three` | Stacking |
+| Stack bowls (2 / 3) | `stack_bowls_two/three` | Stacking |
+| Handover block / mic | `handover_block` | Bimanual coord. |

+| Scan object | `scan_object` | Mobile manip. |
Pass a comma-separated list to `--env.task` to run multiple tasks in a single eval sweep.
+
+ `open_laptop` is currently broken upstream (its `check_success()` uses
+ `self.arm_tag`, which is only set inside the scripted-expert `play_once()`
+ path and therefore unavailable during normal policy eval). Avoid it until the
+ upstream bug is fixed, or patch the task to default `self.arm_tag = "left"` in
+ `load_actors()`.
