Summary

MuJoCo actuator shortcut elements (<position>, <velocity>) implicitly set biastype=affine without writing it to the XML. Newton's MJCF parser only captured explicitly written attributes, so the custom attribute default (biastype=none) was used instead. This caused the CTRL_DIRECT path to create actuators with biastype=none, meaning biasprm values were ignored and actuator forces were incorrect.

For example, a <position kp="100" joint="j1"/> actuator should produce force = kp * (ctrl - pos) - kv * vel (affine bias), but was producing force = kp * ctrl (no bias).

Changes

  • import_mjcf.py: After parse_custom_attributes, set implicit type defaults per actuator shortcut type to match MuJoCo's user_api.cc behavior. Explicit XML values still take precedence.
  • test_import_mjcf.py: Added TestActuatorShortcutTypeDefaults with 6 tests covering:
    • position shortcut gets biastype=affine
    • velocity shortcut gets biastype=affine
    • motor shortcut keeps biastype=none
    • general reads biastype from XML
    • position has gaintype=fixed
    • Full round-trip: MJCF -> Newton -> MuJoCo spec -> compiled model matches native

Test plan

  • uv run --extra dev -m newton.tests -k "TestActuatorShortcutTypeDefaults" — 6/6 pass
  • uv run --extra dev -m newton.tests -k "test_import_mjcf" — 134/134 pass (no regressions)
  • Pre-commit clean

Summary by CodeRabbit

  • Bug Fixes

    • Position and velocity actuator shortcuts now get correct implicit bias defaults, ensuring consistent actuator behavior and aligning shortcut handling with MuJoCo expectations.
  • Tests

    • Added comprehensive tests verifying default bias/gain behavior for position, velocity, motor, and general actuator shortcuts, including end-to-end verification with MuJoCo compilation.

MuJoCo shortcut elements (position, velocity) implicitly set
biastype=affine without writing it to the XML. Newton's MJCF parser
only captured explicitly written attributes, so the custom attribute
default (biastype=none) was used instead. This caused the CTRL_DIRECT
path to create actuators with biastype=none, meaning biasprm values
were ignored and actuator forces were incorrect.

Set the implicit type defaults in the parser after
parse_custom_attributes, matching MuJoCo's user_api.cc behavior.
Explicit XML values still take precedence.

📝 Walkthrough

Walkthrough

Adds implicit mujoco:actuator_biastype = 1 (affine) for actuator shortcut types position and velocity in parse_actuators; adds tests validating implicit biastype/gaintype defaults (the test class is duplicated in the diff).

Changes

Cohort / File(s) Summary
Actuator parsing
newton/_src/utils/import_mjcf.py
After merging per-actuator attributes in parse_actuators, inject mujoco:actuator_biastype = 1 for shortcut types position and velocity when not specified; no other actuator or per-DOF logic changed.
Tests (new / duplicated)
newton/tests/test_import_mjcf.py
Adds TestActuatorShortcutTypeDefaults (tests for biastype/gaintype defaults and MuJoCo compile round-trip). The test class appears twice in the diff (duplicate declaration).

2106-2117: LGTM — one optional cleanup suggestion.

The biastype injection is correctly placed (after parse_custom_attributes, before actuator_values assembly), the if key not in parsed_attrs guard properly preserves explicit XML overrides, and the value 1 (affine) matches MuJoCo's behavior for position/velocity shortcuts.

Regarding gaintype: The registered default for mujoco:actuator_gaintype is already 0 (fixed), which matches MuJoCo's implicit default for position/velocity shortcuts, so no injection is needed.

Optional: Hoist shortcut_type_defaults out of the per-actuator loop.
The dict is a static constant but is recreated on every iteration. Moving it to module or function scope clarifies intent:

6028-6082: Please document “fails without fix” verification for these regression tests.

The new tests are great, but per test policy, please note in the PR (or test plan) that they fail when the implicit biastype defaulting is removed, and pass once re‑applied.

As per coding guidelines: "Always verify regression tests fail without the fix by temporarily reverting it, confirming test failure, then reapplying the fix and verifying test passes".

# Description

This PR adds the option to set wrench positions to
`set_external_force_and_torque`. This is a non-breaking change as the
positions are passed as an optional argument. When no positions are set,
the function defaults to the original implementation, that is, no
positions are passed to PhysX. The PR also adds tests to check that the
position values are correctly set into their buffer, but does not check
if the resulting wrenches are correct. I did test the Quadcopter task
before and after this PR and the training results are exactly the same.

As of now, the function follows the original layout. But it could make
sense to offer the option to set the position in either the link frame
or the CoM frame. This would follow the recent changes made to the
set_pose and set_velocity methods for instance. However, this would be a
breaking change. Hence, for now, this has not been implemented. One
could also argue, that this could be done prior to feeding the positions
outside this method. Please let me know what you feel is best, and I'll
update the PR accordingly.

If one wanted to test the resulting wrenches, it would require a simple
test articulation like a 1kg sphere that would be used to accurately
compute the expected velocities. This is also feasible, but I feel like
this test is more on the PhysX side of things, let me know.

This change will require an update of the API documentation to include
the position argument.

Fixes newton-physics#1678
