Choose and recover within a budget
A router uses earlier measured policy success to choose an action policy. A judge checks when a policy returns, and recovery shares a limited budget. A running policy does not wait for the reasoning model.
Compare the experiments carefully
The authors report 95.9% success over 3,000 LIBERO-Pro episodes versus 94.7% for the best single-agent baseline in their policy pool. The separate RoboTwin comparison used different execution windows and a separate host for MEDex; its small differences should not be treated as a general advantage.

What you can do

Where the evidence stops
No simulator or robot run. Calibration, reset-state separation and transfer beyond the compared tasks need independent checking.

The record over time (1)
Dated source checks and published explanations. An observation date can differ from the original release date.
- · Added to Current
REA studies how a robot can keep executing a fast control policy while a slower reasoning model plans or checks at selected boundaries.
