The short version

The problem
Robots often choose their next move from what they see right now, so they can lose track of earlier steps or repeat a motion back and forth. Meanwhile, many powerful robot models are difficult to reproduce because their training data or methods are not public.
The idea
The paper presents a robot-control model trained using public data and releases its full pipeline. It also gives the model a small, reusable memory: instead of reprocessing old camera images, it stores compact summaries of recent moments, like brief notes a person keeps while following a multi-step instruction.
What it got
The model is a leading public-data system on two robustness tests and performs competitively on other robot tasks. With memory, back-and-forth motion episodes were about four times less common.

Modules from this paper

REKI: Registering Knowledge in VLAs

REKI pairs a vision-language backbone with a flow-matching action expert and a single-stage pretraining recipe over curated public robot, human, and vision-language data.

REKI: Register Memory for History-Aware Robot Control

A robot action expert needs recent visual history without repeatedly processing old frames; REKI summarizes each frame in learned registers and carries their attention keys and values through a rolling cache.
