Remove ensure_nonstatic_links option from importers by adenzler-nvidia · Pull Request #1682 · newton-physics/newton

adenzler-nvidia · 2026-02-18T13:17:24Z

Summary

Remove the ensure_nonstatic_links and static_link_mass parameters from parse_urdf(), parse_mjcf(), ModelBuilder.add_urdf(), and ModelBuilder.add_mjcf()
Zero-mass bodies are now always preserved as-is, which is the correct default behavior for sensor frames and reference links
Users who need nonzero mass can set it directly on the builder after import

Test plan

Pre-commit hooks pass
TestMuJoCoSolverZeroMassBody passes (zero-mass body handling still works)
TestMimicConstraints passes (URDF importer unaffected)
Grep confirms no remaining references to ensure_nonstatic_links or static_link_mass

Summary by CodeRabbit

Breaking Changes
- Importers no longer accept the options to auto-assign a small mass to zero-mass links; zero-mass links are preserved as defined during import.
Tests
- Test names and expectations updated to reflect the removed importer options and the preserved zero-mass behavior; docstrings adjusted accordingly.

Remove the ensure_nonstatic_links and static_link_mass parameters from parse_urdf(), parse_mjcf(), ModelBuilder.add_urdf(), and ModelBuilder.add_mjcf(). Zero-mass bodies are now always preserved as-is, which is the correct default behavior for sensor frames and reference links. Users who need nonzero mass can set it directly on the builder after import.

📝 Walkthrough

Walkthrough

This PR removes the public API parameters ensure_nonstatic_links and static_link_mass from URDF and MJCF importers (add_urdf, add_mjcf, parse_urdf, parse_mjcf) and deletes the internal code paths that would assign a small nonzero mass/inertia to zero-mass links during import.

Changes

Cohort / File(s)	Summary
Importer public APIs `newton/_src/sim/builder.py`	Removed `ensure_nonstatic_links` and `static_link_mass` parameters from `add_urdf` and `add_mjcf` signatures and removed passing those args into parse calls.
URDF importer internals `newton/_src/utils/import_urdf.py`	Removed `ensure_nonstatic_links` and `static_link_mass` parameters from `parse_urdf` and deleted code that forced nonzero mass/inertia for zero-mass shapes when the flag was set.
MJCF importer internals `newton/_src/utils/import_mjcf.py`	Removed `ensure_nonstatic_links` and `static_link_mass` parameters from `parse_mjcf` and deleted code that assigned surrogate mass/inertia to zero-mass bodies when the flag was set.
Tests and docs `newton/tests/test_import_urdf.py`, `newton/tests/test_import_mjcf.py`, `newton/tests/test_mujoco_solver.py`	Updated tests to remove `ensure_nonstatic_links` usage, renamed/removed tests that validated the opt-in surrogate-mass behavior, and adjusted docstrings mentioning the removed parameter.

…ure-nonstatic-links

Main added TestZeroMassBodies which references the removed ensure_nonstatic_links parameter. Remove the opt-in test entirely and rename the remaining test to reflect the new behavior where zero-mass bodies are always preserved as-is.

In `@newton/tests/test_import_mjcf.py`:
- Around line 6119-6124: Update the TestZeroMassBodies class docstring to
include the SI unit for mass by adding "[kg]" inline (e.g., "mass [kg]") so both
occurrences referring to mass include the unit; edit the docstring in the
TestZeroMassBodies class to read something like "zero-mass bodies (sensor
frames, reference links). These should keep their zero mass [kg] after import"
while preserving the existing wording.
