POD-RoPE: Rotary Position Encoding over Physical Observation Distributions for V
Overview
POD-RoPE is a new positional encoding method for embodied AI that represents observation footprints as distributions over camera centers, viewing directions, and sampling times. It enables geometry-aware attention by encoding relative relationships between distributions and supports efficient information selection and content aggregation. Evaluated across multiple robot policy architectures and real-world tasks, POD-RoPE improves success rates and achieves significant speedups over existing methods.
