HODAgent Paper Withdrawn Before Public Review

By Sophia ChenAUG 22, 20261 min read

Single-source brief: The work describes a humanoid service-agent system, but its paper is withdrawn and its claims remain unconfirmed.

What changed

arXiv shows the HODAgent paper was withdrawn on August 20.

The listing says a company directive required internal review before public release.

No PDF is available from the withdrawn listing.

That blocks outside review of the method, tests, and reported results.

The abstract described HODAgent as a “System-2” agent for service humanoids.

It aimed to handle user intent, task changes, action execution, and outcome checks.

Its design included an Env-Interactor, Planner, Executor, and hierarchical Memory.

The system was meant to accept new requests while a robot moved.

It also claimed a shared interface for simulation and Unitree G1 robots.

The work appears to be a research claim, not a confirmed product deployment.

The abstract reported simulation results across 164 cases.

It also reported physical-robot pass rates for atomic, composite, and complete tasks.

Those figures cannot be checked from the withdrawn paper’s available materials.

No independent confirmation was supplied.

The key question is not the headline score.

It is whether task revision works safely during real service work.

Runtime behavior, fault handling, and long-shift reliability are not established here.

The paper may return after review. Until then, HODAgent remains an unverified research report.
