arXiv:2510. 18348v2 Announce Type: replace-cross Abstract: State-of-the-art perceptive Reinforcement Learning controllers for legged robots typically either (i) impose oscillator-or IK-based gait priors that constrain the action space, bias policy optimization, and limit adaptability across robot morphologies, or (ii) operate "blind," making them unable to anticipate hind-leg terrain and brittle to observation noise.

arXiv:2606. 15896v1 Announce Type: cross Abstract: Learning-based quadrupedal locomotion typically relies on complex reward formulations that entangle task specification, operational limits, gait preference, and terrain adaptation within a single optimization objective.

FootQuery is a perceptive locomotion framework that retrieves depth information from a robot’s own history by querying each foot’s predicted next touchdown. The policy uses proprioceptive predictions of touchdown locations and uncertainties to sample relevant historical depth frames, fuses these per‑foot features with global visual memory, and generates control actions. In simulation and on a real Unitree G1 robot, FootQuery enables continuous traversal of complex outdoor stairs, indoor routes, platforms, and gaps, outperforming component ablations.
