Use a Python +3.10--3.13 environment on Linux with a supported NVIDIA GPU and driver. The +non-`torch` extras are preferred for EmbodiChain because the simulation +environment normally already provides PyTorch; the `-torch` variants delegate +the PyTorch version requirement to cuRobo. Keep cuRobo in the same Python +environment that runs the simulator. + +## Configure a control part + +The cuRobo robot model and the per-control-part profile are both auto-generated +internally - no external cuRobo robot YAML (e.g. `franka.yml`) and no +`robot_profiles` config are needed. On the first plan, the adapter fits collision +spheres to each link of the robot's URDF and writes a cuRobo V2 robot YAML (see +[Auto-generated robot YAML](#auto-generated-robot-yaml)). The tool frame, TCP +offset, and base link are read from the control part's IK solver, and the +simulator->cuRobo joint mapping is identity (the generated YAML reuses the +URDF's own joint names). The control part is selected at plan time through +`CuroboPlanOptions.control_part` and validated against `robot.control_parts`. + +Lock non-controlled joints (for example gripper joints) in the cuRobo robot +profile so they are not exposed as active planner joints. The simulator values of +those joints must remain equal to the V2 profile's `lock_joints` values while a +plan is executed; the adapter intentionally preserves non-control simulator +joints in the full-DoF atomic-action output. For example, the Panda V2 profile +locks both fingers at `0.04`, so use the same simulated finger state or include +the fingers in the planned control part. A mismatch means cuRobo validates a +different collision geometry from the one replayed in DexSim. + +~~~python +from embodichain.lab.sim.planners import ( + CuroboPlannerCfg, + CuroboWorldCfg, + MotionGenCfg, + MotionGenerator, +) + +planner_cfg = CuroboPlannerCfg( + robot_uid="my_franka", + planner_type="curobo", + world=CuroboWorldCfg(rigid_objects=[demo_block]), +) +motion_generator = MotionGenerator(MotionGenCfg(planner_cfg=planner_cfg)) +~~~ + +The robot configuration must be a cuRobo V2 robot profile with collision +spheres and self-collision data; the adapter generates this from the robot's +URDF automatically. A plain URDF alone is not sufficient for collision planning +without that sphere-fitting step. + +The adapter automatically rebases simulator-world Cartesian goals and dynamic +obstacle poses through the live simulator control-part base, so parallel arena +offsets and a moved robot base are handled. If the simulator and cuRobo base +frames use different fixed conventions, set +`CuroboPlannerCfg.sim_base_to_curobo_base` to the transform from the simulator +base to the cuRobo base. Collision-world poses are authored in the cuRobo +base/world frame. `tool_frame_to_tcp` (read from `solver.tcp_xpos`) converts an +EmbodiChain TCP goal into the chosen cuRobo tool frame when the solver's end link +is not itself the TCP. By convention, the adapter uses +`T_curobo,X = T_curobo,sim_base @ inv(T_world,sim_base) @ T_world,X`. It obtains +the simulator base from the control part's IK solver root. + +`CuroboPlannerCfg.use_cuda_graph` defaults to `False` for the same DexSim GPU +stream-safety reason. Enable it explicitly only after validating the local +simulation stack. + +The collision world is always auto-generated from live `RigidObject` meshes via +`CuroboWorldCfg.rigid_objects`: the adapter reads each object's mesh +(`get_vertices` / `get_triangles`) and world pose (`get_local_pose`) and writes a +cached cuRobo scene YAML on the first plan, using +`CuroboWorldCfg.obstacle_representation` (`"cuboid"` by default - a local-frame +AABB placed as an OBB via the object pose; also `"mesh"` for the exact triangle +mesh, or `"sphere"` to fit spheres with cuRobo's `fit_spheres_to_mesh`). +Generated poses are authored in the cuRobo base/world frame, so this is exact +when the robot base sits at the simulator world origin. For obstacles that move +or live in an offset base frame, also declare their names in +`CuroboWorldCfg.dynamic_obstacle_names` and update poses at plan time through +`CuroboPlanOptions.dynamic_obstacle_poses` (provision +`CuroboWorldCfg.collision_cache` before planning). With the default shared world +(`multi_env=False`), all batch rows must provide the same obstacle pose; set +`multi_env=True` when each environment needs its own collision-world instance +(for example, different dynamic obstacle poses). In that mode the generated world +YAML is cloned into one V2 scene per batch row. An empty world (`rigid_objects` +left `None`) is likewise materialized once per row so its per-environment cache +is allocated. Dynamic pose updates still require the named geometry to already +exist in every scene; the adapter does not insert new geometry at runtime. + +## Auto-generated robot YAML + +On the first plan, the adapter auto-derives the cuRobo robot profile from the +robot's URDF and solver, so nothing robot-specific needs to be hardcoded: + +- `robot_config_path` is produced by `generate_curobo_robot_yaml`, which fits + collision spheres to each link mesh and writes a cuRobo V2 robot YAML. +- The TCP, tool frame, and base link are read from the robot's solver + (`robot._solvers[control_part]`): `tool_frame_name` <- `solver.end_link_name`, + `tool_frame_to_tcp` <- `solver.tcp_xpos`, `base_link_name` <- + `solver.root_link_name`. +- `sim_to_curobo_joint_names` is the identity mapping, since the generated YAML + reuses the simulator's own URDF joint names. + +The generated YAML is cached on disk (default `$XDG_CACHE_HOME/embodichain_curobo` +or `~/.cache/embodichain_curobo`) keyed by the URDF path, URDF content, control +part, tool frame, and fit parameters, so editing the URDF or changing the fit +settings regenerates automatically and subsequent inits reuse the cache. Tune the +fit with `CuroboPlannerCfg.auto_gen` (`fit_type="voxel"` by default for fast +first-generation; `"morphit"` for best quality; `force=True` to bypass the cache). +The default `sphere_density=0.1` keeps the per-link sphere count low (~80 for a +Panda) so planning stays fast; raise it for tighter collision coverage. + +## Generate a motion + +MotionGenerator passes start_qpos and control_part to the cuRobo backend.

IsaacLab's implementation is a +useful reference for backend boundaries, named-joint remapping, and collision +world lifecycle, but it uses the incompatible cuRobo V1 `MotionGen` API and is +not copied. + +cuRobo requires a CUDA-capable NVIDIA GPU.

The selected +profile explicitly maps between simulator joint names and cuRobo joint names; +the backend never assumes that simulator indices and cuRobo indices are equal. +Any non-controlled joints, including gripper joints, must be locked in the +cuRobo V2 robot profile so they do not appear in the backend's active joint +list. Their preserved simulator values must equal the V2 profile's +`lock_joints` values during planning and atomic-action playback; the first +release documents this cross-model lock contract but does not automatically +validate joint-name/value equivalence. The backend rejects an active-joint/ +profile mismatch rather than planning collision geometry that EmbodiChain will +not execute. + +`CuroboPlanner` is a `BasePlanner` implementation. It lazily imports V2 +types, creates and warms a `MotionPlanner` for a one-environment request and a +V2 `BatchMotionPlanner` for a multi-environment request, then returns the +standard result fields: + +```text +success: bool tensor (B,) +positions: float tensor (B, N, controlled_dof) +velocities: float tensor (B, N, controlled_dof) or None +accelerations: float tensor (B, N, controlled_dof) or None +dt: float tensor (B, N) +duration: float tensor (B,) +xpos_list: float tensor (B, N, 4, 4) when FK is available +``` + +The planner supports `EEF_MOVE` by converting EmbodiChain world-frame matrices +to cuRobo target poses, including the selected robot base transform and TCP. +It supports `JOINT_MOVE` with cuRobo's joint-space planning API. Unsupported +move types fail before planning with a clear `ValueError`. + +### Motion-Generator Integration + +`MotionGenerator` registers `"curobo"` alongside existing planner types. +`BasePlanner` gains two explicit extension points: + +- `preinterpolate_targets: bool`, which defaults to `True`; +- `supports_joint_move: bool`, which defaults to `False` and keeps + Cartesian-only backends on local joint interpolation for atomic phases; +- `with_motion_context(options, *, start_qpos, control_part)`, whose base + implementation returns the supplied options unchanged. + +Planner capabilities replace the current `isinstance(NeuralPlanner)` decision: + +- planners declare whether EmbodiChain pre-interpolation is appropriate; +- CuRobo declares it is not appropriate for Cartesian targets, so it receives + the original `EEF_MOVE` targets and performs its own collision-aware IK and + trajectory optimization; +- planners receive the same runtime context through + `with_motion_context(...)`, rather than `MotionGenerator` copying fields + only for one concrete planner. + +This prevents a Cartesian action from being silently converted through +EmbodiChain IK before CuRobo sees it. It also ensures the start position and +the requested control part reach `CuroboPlanOptions` on every call. + +### Collision-World Boundary + +The initial collision world is explicit and deterministic. `CuroboWorldCfg` +points to a cuRobo V2 scene profile containing mesh and primitive obstacles. +At initialization the adapter loads this static scene once and warms the +planner. Before a plan, callers may supply poses keyed by the configured +dynamic obstacle names; the adapter verifies every name and updates only those +poses. Adding or removing geometry requires an explicit world reload rather +than a fragile implicit scene scan. + +All obstacle poses, goal poses, robot base poses, and tool poses use a single +documented world coordinate convention. The adapter converts EmbodiChain +4x4 matrices to cuRobo's position/quaternion representation at this boundary +and tests the quaternion ordering directly. Static collision YAML is authored +in the cuRobo base frame and therefore applies to fixed-base scenes; a moving +base must publish relevant obstacles through named dynamic updates. + +### Atomic-Action Integration + +The existing data flow remains intact: + +```text +AtomicActionEngine + -> TrajectoryBuilder.plan_arm_traj + -> MotionGenerator.generate + -> CuroboPlanner.plan + -> PlanResult + -> full-DoF ActionResult trajectory +``` + +`ActionCfg.planner_type` documents and validates `"curobo"`. When the action +uses `motion_source="motion_gen"` and a CuRobo generator, the builder creates +`CuroboPlanOptions`, disables EmbodiChain Cartesian pre-interpolation, and +embeds the controlled joint plan into full robot DoF exactly as it does for +other planners. + +The supported first-release atomic surface is: + +- `MoveEndEffector`; +- movement phases of `PickUp`, `Place`, `Press`, and `MoveHeldObject` in a + static collision scene; +- `MoveJoints` when explicitly configured with `motion_source="motion_gen"`. + +Default action behavior remains unchanged (`motion_source="ik_interp"`). +Coordinated two-arm actions reject the CuRobo backend until they have a +separate multi-arm planning design. Because attached-object collision modeling +is excluded, users must not claim collision-aware carrying for a held object +until that later extension is implemented. + +### Optional Dependency Behavior + +The public planner package exports its configuration types without importing +cuRobo. Constructing or calling `CuroboPlanner` performs the dependency and +CUDA checks. A missing dependency raises an error that names the official V2 +installation command family (`.[cu12]` or `.[cu13]`) and links to the project +installation instructions. Tests that require the real library use +`pytest.importorskip("curobo")`. + +## Error Handling and Correctness Rules + +- Missing `robot_uid`, unknown control part, absent profile, joint-name + mismatch, invalid robot/world profile, or incompatible batch size fail before + a CUDA plan is launched. +- A failed cuRobo solution becomes a per-environment `success` tensor. Its + trajectory is held at `start_qpos`, matching the existing + `AtomicActionEngine` failed-environment behavior. +- Planner output is reordered from cuRobo named joints back to EmbodiChain + control-part order before it reaches `PlanResult`. +- Output tensors are moved to the robot's device and have the exact batch and + DoF shapes expected by `BasePlanner`. +- The implementation validates that an action's requested `planner_type` + matches the already constructed `MotionGenerator` planner; it never silently + plans with TOPPRA or NeuralPlanner under a CuRobo label. + +## Verification Strategy + +1. **Pure unit tests, no cuRobo required** + - config validation, registry/export behavior, optional-import errors; + - planner capability propagation through `MotionGenerator`; + - named-joint reorder and matrix/pose conversion helpers; + - `TrajectoryBuilder` and `MoveJoints` routing with a fake CuRobo backend. + +2. **Optional CUDA/cuRobo integration tests** + - create a V2 planner with a Panda profile and static obstacle; + - plan a collision-free pose trajectory and assert success, finite values, + start state, endpoint tolerance, joint ordering, and time fields; + - update a configured obstacle pose and verify the update reaches the + backend. + +3. **DexSim end-to-end test** + - create a single-arm robot and a matching static obstacle; + - execute `AtomicActionEngine + MoveEndEffector` with + `planner_type="curobo"`; + - assert a full-DoF trajectory, per-environment success, and target-pose + tolerance after playback.
