Systems and methods for computing capture-point–aware footstep sequences for a legged robot so the body stays within a recoverable balance envelope while traversing planned terrain.

Claims

Independent claims cover generating a step path from robot state and terrain maps, adjusting footholds using capture-point constraints, and updating the path when perception detects deviations.

Technical analysis

This is foundational locomotion IP for Spot-class platforms: instead of open-loop gait tables, the controller continuously recomputes footholds against a capture-point model. That is what lets quadrupeds recover from slips and replan mid-stride without freezing. Competitors without equivalent planning depth tend to fall back to slower, more conservative gaits on cluttered floors.

Commercial impact

Protects core stair/uneven-terrain behavior that industrial inspection customers buy Spot for. Licensing or design-around pressure shows up whenever a new quadruped claims autonomous stair traversal in facilities.
