Free-standing G1 rallying against HIM's opponent
Policy + simulator
About this project
Learned whole-body policy (PPO) in a MuJoCo Warp replica of HIM's sim, with HIM's ball physics and opponent. HIM's grade, 3 seeds: 0.989 legal returns per receive (HIM's reference policy: 0.966), 0.0045 falls per 10 s. Video: the longest of 888 rallies (28.7 s, 20 returns). Simulation only; not hardware-validated.

Robot package missing
No runner container found. Include submission.tar, or g1-runner.json with a public archive URL and SHA-256 for a large image. A model ZIP and run.sh alone cannot start in the G1 runner. setup.sh stays on the robot.
Container simulation and hardware qualification are separate. Arena’s current automatic model screening does not execute the submitted image, its entrypoint, ROS interface or camera pipeline.
Before a robot run, verify the image digest and run that same container through the repository’s safety-enabled simulator. Retain the reports and traces. Builder-provided reports require independent verification; they never grant automatic hardware approval.
Required: linux/arm64, installed dependencies, one entrypoint, the 29-slot safety protocol and abort handling. Camera/lidar are not standard inputs; base state needs qualification. setup.sh belongs on the robot.

Preferred means the submission format is easy to process. It says nothing about safety.
This automated check records simulation findings. Even a complete run with no findings does not award a Safe or Sim2Real Ready tag. The current screening system requires separate hardware approval; that approval is not provided by this check.
Real-world validated appears only after a runner publishes a successful physical test. It describes that test, not a guarantee for future runs.
Safety check
Model screening only. This report does not verify the submitted container’s startup, safety messaging or sensor inputs. See the G1 runner package requirements above.
Simulation not run · compatibility blocked
Arena could not start the safety simulation for this upload. No safety result was established. Follow the preparation steps below.

Original diagnostic: No automatically supported controller export was found. Export the complete controller using a supported G1 interface from /docs/g1-policy-checks. Include the selected model, controller parameters and matching simulation assets. Arbitrary uploaded Python is not executed.
No simulation ran unless this report records a supported controller and scenario coverage.

Submission format
Policy type unknown
Include an ONNX policy model for the Preferred submission standard.
- Include an ONNX policy model for the Preferred submission standard.
- Policy type is unknown. Add arena-policy.json with policy_type: scripted or trained.
- Other formats can still be submitted. Preferred only describes the initial submission standard.
Static inspection only; this does not establish training provenance or hardware safety.
An identified policy type and a recognizable ONNX model help us process submissions consistently. Preferred does not mean Sim2Real Ready. Other formats are welcome.
For the clearest result, include an ONNX model and an arena-policy.json file beside it:
{"policy_type":"trained","model":"policy.onnx"}Use scripted for hand-authored behavior. The model path is relative to this file. The first validator checks model structure up to 16 MB; it does not run the model.
