What they did and found
A rolling window approach divides the work of cleaning up predictions across planning cycles. It keeps a moving block of near-term and farther actions, fully refining the first block while slowly improving the rest as new data arrives.
Why it matters
This can cut decision time in live robot control, but gains depend on task speed, hardware limits, and how fast data arrives.
The rolling window keeps several future actions in view and updates plans quickly as new data arrives, helping faster, smoother control.
In a warehouse, a robot could replan faster if a worker moves, but accuracy may lag if scenes change rapidly or longer horizons are needed.

What remains uncertain
Predictions may lag when scenes change quickly; benefits depend on hardware, task dynamics, data throughput, and real-world conditions.
