Researchers have developed RingNav, a novel visual heading estimator designed for tiny robots with limited computational resources. This model constrains its memory to a circular manifold (S^1), learning only the turn between consecutive images to estimate heading. In tests on the TartanAir Visual SLAM Challenge, RingNav demonstrated a 27% reduction in mean absolute turn error and a 15% decrease in accumulated heading error over 4 seconds compared to a similarly sized learned-memory model. The system is capable of running at 27.3Hz on a Raspberry Pi Zero 2W and can achieve 33.4Hz on an ultra-low power GAP8 processor. AI
