DAWN (Denoising and Alignment in World models for Noise-robustness) is a perception framework that builds noise robustness directly into a world model for vision-based legged locomotion. It achieves this by feeding noisy depth to the encoder while reconstructing clean depth, and by using contrastive learning to align latent states of noisy and clean depth. The method requires no manual filter tuning, incurs no extra inference cost, and enables zero‑shot quadruped parkour on a Unitree Go1, successfully traversing stairs, gaps, and steps from raw depth observations.

DAVIO is a dense monocular‑inertial SLAM system that leverages a single multi‑view depth model (Depth Anything 3) for both initialization and mapping. It starts up quickly by solving a feature‑free linear system from a five‑image window and IMU pre‑integration, then uses a VIO filter whose metric poses condition the depth model during tracking. The system corrects residual scale along viewing rays, preserves metric baselines, and refines the map with a gravity‑preserving sub‑map graph, achieving earlier start‑up, lower localization error, and more accurate dense maps than state‑of‑the‑art feed‑forward mappers on both EuRoC and building‑scale ORI datasets.

DefVINS is a visual‑inertial odometry pipeline tailored for deformable scenes, breaking the rigidity assumption of traditional VIO. It decomposes the odometry state into a rigid, IMU‑anchored component and a non‑rigid scene warp using an embedded deformation graph. The authors also introduce VIMandala, the first real‑world benchmark with ground‑truth camera poses for deformable VIO, and extend the synthetic Drunkard’s benchmark with inertial data, demonstrating that DefVINS outperforms both rigid and non‑rigid baselines.
