The Humanoid Lowers Itself From a Walk Into a Crawl
REACH links variable-height bipedal motion, contact-rich crawling and LiDAR planning so a Unitree G1 can traverse tested confined spaces.
Summary
REACH links variable-height bipedal motion, contact-rich crawling and LiDAR planning so a Unitree G1 can traverse tested confined spaces.
Crouched walking alone cannot fit a humanoid through every low-clearance route. REACH divides the problem into variable-height bipedal locomotion from 1.27 to 0.50 meters, crawling from 0.50 to 0.20 meters and a bidirectional transition policy between the two. A history-conditioned latent state captures proprioceptive terrain and contact context during crawling, while a LiDAR planner converts point clouds into three-dimensional paths and proactive height commands. The authors report real-world height and velocity tracking, mode transitions and confined-space traversal on a Unitree G1. These demonstrations concern the tested robot and environments; they do not establish unsupervised operation in arbitrary confined or hazardous spaces.
