XR-1 RoboCasa

OpenRAL wrapper for Xiaomi Robotics' XR-1 RoboCasa checkpoint on the PandaMobile kitchen embodiment. The package points at the pinned upstream safetensors; it does not copy weights.

How it works

XR-1 combines Qwen3-VL-4B-Instruct with a 36-layer DiT action head. OpenRAL runs the exact torch 2.8 / transformers 4.57.1 / FlashAttention stack in a sidecar, pads the 8-D physical state to XR-1's internal 60-D state tensor, and applies Xiaomi's 0.95 center crop before returning the checkpoint's first seven decoded action channels.

Observation -> action contract

Direction	Key	Shape	Notes
in	camera1, camera2, camera3	three RGB 256x256 frames	left/right base and wrist
in	observation.state	(8,)	seven arm joints plus one gripper value
out	action chunk	(T, 7)	delta XYZ, delta axis-angle, gripper

Upstream model and training

Field	Value
Source repo	XiaomiRobotics/Xiaomi-Robotics-1-RoboCasa
Base model	XR-1 5B post-trained for RoboCasa
Paper	Xiaomi-Robotics-1

Parameters	5.44B
Training data	Xiaomi's RoboCasa benchmark post-training data

Supported robots

Robot	Embodiment tag	Status	Notes
PandaMobile in RoboCasa	panda_mobile	integration-ready	Upstream evaluates RoboCasa v0.2; OpenRAL's current backend version must still be benchmark-correlated.

Sensors required

Three RGB streams at 256x256 or larger and an 8-D arm/gripper state.

Quick start

just sync --group sidecar-wire --group robocasa
OPENRAL_ALLOW_REMOTE_CODE=1 openral sim run \
  --config scenes/sim/xr1_robocasa_pnp.yaml \
  --rskill rskills/xr1-robocasa

Reproduction

The command above validates the OpenRAL observation/action wiring. It is not a reproduction of Xiaomi's published RoboCasa score because Xiaomi evaluates RoboCasa v0.2 while OpenRAL currently provisions its own pinned kitchen stack.

Evaluation

No benchmark JSON is shipped until a full upstream-version-matched run is completed. Integration claims are limited to schema and adapter validation.

License

The rSkill metadata and upstream XR-1 code/checkpoint are Apache-2.0. Loading requires OPENRAL_ALLOW_REMOTE_CODE=1 because the HF repo ships executable custom Transformers code.
