Does π0 run on ARX5?

Capabilities

Caveats

• Community-reported only (RoboChallenge benchmark by Dexmal/Hugging Face); not documented by Physical Intelligence or maintainer-tested.
• The paper does not name the codebase; openpi is recorded because RoboChallenge maintains an openpi fork and π0 is open-sourced there.
• Per-task fine-tuned π0 succeeded unevenly on ARX5 tasks, e.g. 80% on place shoes on rack but 0% on open the drawer and fold dishcloth.

   RoboChallenge (Table30) real-robot benchmark fleet includes a table-mounted ARX-5 arm; 10 of the 30 tasks run on ARX5.

   π0 is one of the baselines fine-tuned and evaluated on all 30 Table30 tasks, including the ARX5 tasks (results table: Pi0 column).
