Handle zero-mass bodies and flip ensure_nonstatic_links default by adenzler-nvidia · Pull Request #1635 · newton-physics/newton

adenzler-nvidia · 2026-02-13T16:36:18Z

SolverMuJoCo: skip explicit inertia for zero-mass bodies when building the MjSpec, letting MuJoCo's compiler handle them natively. Previously, passing fullinertia with zero eigenvalues caused spec.compile() to reject the model.

Flip ensure_nonstatic_links default from True to False in MJCF and URDF importers. Models should be trusted as authored — zero-mass bodies (sensor frames, reference links) are valid and don't need fake mass. Users who need the old behavior can opt in explicitly.

Summary by CodeRabbit

Default Behavior Changes
- URDF/MJCF imports now default to not adding small masses to zero-mass links; opt-in to restore prior mass-padding.
Behavior
- Zero-mass bodies are preserved when building MuJoCo models (mass/inertia omitted), letting the simulator handle them.
Tests
- Added tests validating default no-mass handling and the opt-in mass-assignment path.

📝 Walkthrough

Walkthrough

Defaults for ensure_nonstatic_links changed from True to False in URDF/MJCF import and builder entry points; SolverMuJoCo now omits mass/inertia fields when body mass == 0; tests were added to validate default and opt-in zero-mass behavior (duplicate test blocks present).

Changes

Cohort / File(s)	Summary
Builder entrypoints `newton/_src/sim/builder.py`	`add_urdf()` and `add_mjcf()` — changed parameter default `ensure_nonstatic_links: bool` from `True` → `False`.
Import utilities `newton/_src/utils/import_urdf.py`, `newton/_src/utils/import_mjcf.py`	`parse_urdf()` and `parse_mjcf()` — changed parameter default `ensure_nonstatic_links: bool` from `True` → `False`.
MuJoCo solver `newton/_src/solvers/mujoco/solver_mujoco.py`	`add_geoms` — branch added: if body.mass > 0 include mass and inertia fields; if body.mass == 0 omit mass/inertia and provide pose/mocap only.
Tests `newton/tests/test_import_mjcf.py`, `newton/tests/test_mujoco_solver.py`	Added tests for zero-mass bodies (default stays massless; opt-in assigns surrogate mass) and a MuJoCo solver test for zero-mass body. Note: duplicate test blocks appear in both test files.

and apply it only to the solver-dependent test: remove the class-level
`@unittest.skipIf`(hasattr(SolverMuJoCo, "import_mujoco") ...) decorator from
TestZeroMassBodies and instead add a skip (or keep the existing runtime check)

🧹 Nitpick comments (1)

newton/tests/test_mujoco_solver.py (1)
6086-6110: Add an assertion that the zero-mass body stays zero to validate the default behavior.

Right now the test only checks solver creation, so it would still pass if ensure_nonstatic_links silently reverted to mass-correcting zero-mass bodies. Consider asserting that the sensor_frame mass remains 0 (in both Newton and MuJoCo mappings).
Proposed test tightening
         builder = newton.ModelBuilder()
         SolverMuJoCo.register_custom_attributes(builder)
         builder.add_mjcf(mjcf)
         model = builder.finalize()
         solver = SolverMuJoCo(model)
         self.assertIsNotNone(solver.mj_model)
+
+        # Verify the zero-mass body stayed zero in Newton and MuJoCo
+        sensor_idx = model.body_key.index("sensor_frame")
+        self.assertAlmostEqual(float(model.body_mass.numpy()[sensor_idx]), 0.0, places=6)
+        mjc_body_to_newton = solver.mjc_body_to_newton.numpy()
+        mjc_sensor = np.where(mjc_body_to_newton[0] == sensor_idx)[0][0]
+        self.assertAlmostEqual(float(solver.mjw_model.body_mass.numpy()[0, mjc_sensor]), 0.0, places=6)

SolverMuJoCo: omit mass and inertia for zero-mass bodies when building the MjSpec, since MuJoCo's compiler rejects zero-eigenvalue inertia tensors. This handles models with sensor frames or reference links that have zero mass. Flip ensure_nonstatic_links default from True to False in MJCF and URDF importers. Models should be trusted as authored — zero-mass bodies are valid and don't need fake mass. Users who need the old behavior can opt in with ensure_nonstatic_links=True.

beam5's geom had contype="0" conaffinity="0", which caused Newton's MJCF parser to classify it as visual (density=0) and assign zero body mass. With ensure_nonstatic_links now defaulting to False, the zero mass is preserved and MuJoCo rejects the model because beam5 has a hinge joint (moving body). Remove the redundant conaffinity="0" override — the class default (contype="0") combined with the extensive <contact><exclude> pairs already prevents all contacts for beam5.

Pull request overview

This pull request modifies the handling of zero-mass bodies in Newton's MJCF and URDF importers, and updates the MuJoCo solver to properly support them. The changes flip the default value of ensure_nonstatic_links from True to False, trusting models as authored rather than automatically adding fake mass to zero-mass bodies like sensor frames and reference links.

Changes:

Default behavior change: ensure_nonstatic_links now defaults to False for MJCF and URDF imports
MuJoCo solver enhancement: conditionally omits mass and inertia properties for zero-mass bodies, letting MuJoCo handle them natively
Test coverage: added comprehensive tests for zero-mass body handling in both default and opt-in scenarios
