RingNav: Task-Shaped Circular Memory for Visual Heading
RingNav: Task-Shaped Circular Memory for Visual Heading
It reduces mean absolute turn error by 27% and accumulated heading error by 15% on the TartanAir Visual SLAM Challenge. RingNav operates at 27.3Hz on Raspberry Pi Zero 2W and can be deployed on ultra-low power GAP8 processors at 33.4Hz.

arXiv:2610.19044v1 Announce Type: new Abstract: Tiny robots have limited computation and memory, yet visual navigation systems often maintain more state than a task requires. We ask whether persistent memory can instead be shaped by the task. We present \textbf{RingNav}, a \(10.6\)k--parameter visual heading estimator that constrains its memory to the circular manifold \(S^1\). RingNav learns only the turn between co

On the TartanAir Visual SLAM Challenge, RingNav reduces mean absolute turn error by \(27\%\) and accumulated heading error over $4$ sec by \(15\%\) relative to a similarly sized learned-memory model. The structured update also gives exactly zero turn for identical frames and exact cancellation under sequence reversal. Without fine-tuning, RingNav tra
