Validated with MuJoCo 3.3.7, Python 3.12 and EGL offscreen rendering.
- Five regression tests passed using real MuJoCo: both variants and their body
control mappings, gripper closure under external PD with a 20 N force cap,
independent wrist-camera motion, rendering and shared-memory publication of
all three 640 × 480 streams, and loading the portable 33-joint gripper URDF.
- Gripper scene: `nq=40`, `nv=39`, `nu=33`. Hand scene: `nq=50`, `nv=49`, `nu=43`.
Both retain the 29 body joints in the original DDS order. Both also retain
`global_view` in addition to the three streamed cameras.
- The closure test ran 250 physics steps (1 simulated second), reached closure
on both grippers, stayed within the 20 N actuator limit and reported no
MuJoCo numerical warnings.
- Original hand/no-hand model assets are retained. The hand camera variant
adds cameras to a copy of the original model.
The regression tests replace only the DDS dependency with a test double.
A complete live LeRobot/Gym/DDS/ZMQ connection was **not run** here because
Gymnasium, Unitree SDK2/CycloneDDS, ZMQ and OpenCV were unavailable in the
execution environment. `tests/smoke_live.py` is included to run that check on
a machine with the runtime dependencies installed. The ZMQ publisher and
message serializer are unchanged; the configured camera list now includes
the wrists.
The Gym wrapper's acceleration contribution is restricted to three values,
matching its declared 97-value observation space. This fixes the original
wrapper's mismatch of 100 returned values versus 97 declared values.
Prepared against Hugging Face model revision
`a38dc8617f0fca51b38e9354dc58ee35ad850fb5`, with the LeRobot loader and camera
configuration reviewed at `b6ec0060779550c0a157ae34feb89e0cf86012a8`.
The archive is a complete local model-repository update; it has not been
published to Hugging Face.
