# Updates the path to IsaacLab directory in SkillGen documentation

## Description

This PR updates the IsaacLab workspace path for clarity and consistency
in SkillGen documentation.

- Updated `docs/source/overview/imitation-learning/skillgen.rst`
(Download and Setup section)
- Replaced:
  - Before: `cd /path/to/your/isaaclab/root`
  - After: `cd /path/to/your/IsaacLab`

Motivation: Aligns with the repository name and common workspace
convention, reducing confusion and preventing copy-paste errors for
users following setup steps.

Dependencies: None

# Description

This PR adds support for uv as an alternative to conda or venv for
managing virtual environments and adds corresponding support for uv pip
for managing python dependencies. uv and uv pip is significantly faster
than conda and has many useful tools.

If users wish to use the uv workflow they will need to have uv
installed, but otherwise no additional dependencies are added.

Docs should be updated to describe this option. There may need to be
more work done to clean when deactivating the environment. Uv does not
support pre and post activation hooks like conda so cleaning up the
environment variables is slightly more tricky. I would greatly
appreciate feedback to improve this workflow!

# Description

As noted by @liyifan2002 in the related issue, the `.gitignore` rule for
`datasets` also unintentionally ignores changes in
`isaaclab/utils/datasets/`.

This PR fixes the problem by changing the rule from `datasets` to
`/datasets/`, ensuring that only the top-level `datasets/` folder (e.g.,
created when following [this
guide](https://isaac-sim.github.io/IsaacLab/main/source/overview/imitation-learning/skillgen.html#download-and-setup))
is ignored, while keeping `isaaclab/utils/datasets/` tracked.

# Description

This PR removes a `UserWarning` from PyTorch about using
`torch.tensor()` on an existing tensor in `events.py`. It replaces
`torch.tensor(actuator.joint_indices, device=asset.device)` with
`.to(device)` to avoid unnecessary copies.

Warning mentionned:

```bash
/home/spring/IsaacLab/source/isaaclab/isaaclab/envs/mdp/events.py:542: 
UserWarning: To copy construct from a tensor, it is recommended to use sourceTensor.clone().detach() or sourceTensor.clone().detach().requires_grad_(True), rather than torch.tensor(sourceTensor). actuator_joint_indices = torch.tensor(actuator.joint_indices, device=asset.device)

# Description

This MR does the following:

* Adds parsing of instanced prims in
`isaaclab.sim.utils.get_all_matching_child_prims` and
`isaaclab.sim.utils.get_first_matching_child_prim`. Earlier, instanced
prims were skipped since `Usd.Prim.GetChildren` does not return
instanced prims.
* Adds parsing of instanced prims in
`isaaclab.sim.utils.make_uninstanceable` to make all prims
uninstanceable.

These are needed to parse meshes for the dynamic raycaster class in
#3298

# Description

This PR introduces the Population Based Training algorithm originally
implemented in

Petrenko, Aleksei, et al. "Dexpbt: Scaling up dexterous manipulation for
hand-arm systems with population based training." arXiv preprint
arXiv:2305.12127 (2023).

Pbt algorithm offers a alternative to scaling when increasing number of
environment has margin effect.
It takes idea in natural selection and stochastic property in
rl-training to always keeps the top performing agent while replace weak
agent with top performance to overcome the catastrophic failure, and
improve the exploration.

Training view, underperformers are rescued by best performers and later
surpasses them and become best performers

/>


Note:
PBT is still at beta phase and has below limitations:

1. in theory It can work with any rl algorithm but current
implementation only works for rl-games
2. The API could be furthur simplified without needing explicitly input
num_policies or policy_idx, which allows for dynamic max_population, but
it is for future work

# Description

This PR provides remake and extension to orginal environment
kuka-allegro-reorientation implemented in paper:
DexPBT: Scaling up Dexterous Manipulation for Hand-Arm Systems with

and another environment kuka-allegro-lift implemented in paper:

(https://dextrah-rgb.github.io/)
[Ritvik Singh](https://www.ritvik-singh.com/), [Arthur

Ratliff](https://www.nathanratliff.com/), [Karl Van
Wyk](https://scholar.google.com/citations?user=TCYAoF8AAAAJ&hl=en)


Though this is a remake, this remake ends up differs quite a lot in
environment details for reasons like:
1. Simplify reward structure,
2. Unify environment implemtation,
3. Standarize mdp,
4. Utilizes manager-based API

That in my opinion, makes environment study and extension more
accessible, and analyzable. For example you can train lift policy first
then continuing the checkpoint in reorientation environment, since they
share the observation space. : ))

It is a best to consider this a very careful re-interpretation rather
than exact execution to migrate them to IsaacLab

Here is the training curve if you just train with
`./isaaclab.sh -p scripts/reinforcement_learning/rsl_rl/train.py --task
Isaac-Dexsuite-Kuka-Allegro-Lift-v0 --num_envs 8192 --headless`

`./isaaclab.sh -p -m torch.distributed.run --nnodes=1 --nproc_per_node=4
scripts/reinforcement_learning/rsl_rl/train.py --task
Isaac-Dexsuite-Kuka-Allegro-Reorient-v0 --num_envs 40960 --headless
--distributed`

lift training ~ 4 hours
reorientation training ~ 2 days

Note that it requires a order of magnitude more data and time for
reorientation to converge compare to lift under almost identical setup

# Description

Recent isaac sim update introduced a new bug for non-headless scripts
where some scripts were hanging at simulation startup. This change
introduces a new unit test that aims to capture issues like this by
forcing the use of the non-headless app file.

Additionally, the isaac sim CI system has very unstable results for perf
testing, so we are disabling the performance-related tests for the sim
CI.

## Description

This PR introduces the SkillGen framework to Isaac Lab, integrating GPU
motion planning with skill-segmented data generation. It enables
efficient, high-quality dataset creation with robust collision handling,
visualization, and reproducibility.

**Note:** 
- Please look at the cuRobo usage license
![here](docs/licenses/dependencies/cuRobo-license.txt)
- Please look at updated isaacsim license
![here](docs/licenses/dependencies/isaacsim-license.txt)

### Technical Implementation:

**Annotation Framework:**
- Manual subtask start annotations to cleanly separate skill execution
from motion-planning segments
- Consistent trajectory segmentation for downstream dataset consumers

**Motion Planning:**
- **Base Motion Planner (Extensible):**
   - Introduces a reusable planner interface for uniform integration:
-
`source/isaaclab_mimic/isaaclab_mimic/motion_planners/base_motion_planner.py`
   - Defines a minimal, consistent API for planners:
- `update_world_and_plan_motion(...)`, `get_planned_poses(...)`, etc.
   - The cuRobo planner inherits from this base class.
- New planners can be added by subclassing the base class and
implementing the same API, enabling drop-in replacement without changes
to the SkillGen pipeline.
 
- **CuRobo Planner** (GPU-accelerated, collision-aware):
  - Multi-phase planning: approach → contact → retreat
  - Dynamic object attach/detach and contact-aware sphere management
  - Real-time world synchronization between Isaac Lab and cuRobo
  - Configurable collision filtering for contact phases
  - **Tests**:
-
`source/isaaclab_mimic/isaaclab_mimic/motion_planners/curobo/test/test_curobo_planner_cube_stack.py`
-
`source/isaaclab_mimic/isaaclab_mimic/motion_planners/curobo/test/test_curobo_planner_franka.py`
    - `source/isaaclab_mimic/test/test_generate_dataset_skillgen.py`

**Data Generation Pipeline:**
- Automated dataset generation with precise skill-based segmentation
- Integrates with existing observation/action spaces
- Supports multi-env parallel collection with cuRobo-backed planning

**Visualization and Debugging:**
- Rerun-based 3D visualization for trajectory/collision inspection
- Real-time sphere visualization for collision boundaries and contact
phases

### Dependencies:
- **cuRobo**: motion planning and collision checking
- **Rerun**: 3D visualization and debugging

### Integration:
This extends the existing mimic pipeline and remains backward
compatible. It integrates into the manager-based environment structure
and existing observation/action interfaces without breaking current
users.

universal to varied robots
- fix a bug (eef_name) in franka_stack_ik_rel_mimic_env.py
- add new device_name in se3_spacemouse.py

Notes: This PR relies on PR
(https://github.com/isaac-sim/IsaacLab/pull/3174) for surface gripper
support in manager-based workflow.

You can test the whole gr00t-mimic workflow by:
1. record demos:
`./isaaclab.sh -p scripts/tools/record_demos.py --task
Isaac-Stack-Cube-Galbot-Left-Arm-Gripper-RmpFlow-v0 --teleop_device
spacemouse --num_demos 1 --device cpu --dataset_file
datasets/recorded_demos_galbot_suction_rel.hdf5`
2. replay demos:
`./isaaclab.sh -p scripts/tools/replay_demos.py --task
Isaac-Stack-Cube-Galbot-Left-Arm-Gripper-RmpFlow-v0 --num_envs 1
--device cpu --dataset_file
datasets/recorded_demos_galbot_suction_rel.hdf5`
3. annotate demos:
`./isaaclab.sh -p
scripts/imitation_learning/isaaclab_mimic/annotate_demos.py --task
Isaac-Stack-Cube-Galbot-Left-Arm-Gripper-RmpFlow-Rel-Mimic-v0 --auto
--device cpu --input_file
datasets/recorded_demos_galbot_suction_rel.hdf5 --output_file
datasets/annotated_demos_galbot_suction_rel.hdf5`
4. generate dataset:
`./isaaclab.sh -p
scripts/imitation_learning/isaaclab_mimic/generate_dataset.py --task
Isaac-Stack-Cube-Galbot-Left-Arm-Gripper-RmpFlow-Rel-Mimic-v0 --num_envs
16 --device cpu --generation_num_trials 10 --input_file
datasets/annotated_demos_galbot_suction_rel.hdf5 --output_file
datasets/generated_demos_galbot_suction_rel.hdf5`
