About this project

G1 Free Kick. 1 neural network controls all 29 joints of a Unitree G1 for the whole play: it walks up to a futsal ball, lines up, kicks it into a 3 x 2 m goal with its right foot, and then stands still. There is no motion capture and no scripted kick.

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.

Fix my G1 package

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.

Loading builder feedback…

Original diagnostic: Model files were found, but no supported controller interface was identified. Export using a supported G1 interface and declare its safety_adapter in arena-policy.json; see /docs/g1-policy-checks. Preserve the exact observation order, joint order, scaling, normalization and timing. Do not relabel an incompatible checkpoint.

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.

Limitations

This project is shared by its builder. Simulation results do not establish real-world safety. Review the source, dependencies, licensing, and hardware requirements before use.
