宇树科技机器人多楼层复合导航专利获授权

Core Viewpoint - Yushu Technology Co., Ltd. has recently been granted a patent for a "multi-floor composite navigation method and device for robots," which aims to enhance navigation efficiency in multi-floor environments by improving the preservation of grid map information and optimizing path planning [1] Group 1: Patent Details - The patented invention belongs to the field of robot navigation technology [1] - Existing navigation solutions have low preservation of grid map information during multi-floor navigation, leading to suboptimal path planning [1] - The new method segments 3D point cloud maps by floor, significantly improving information preservation [1] Group 2: Methodology - Each floor's 3D point cloud map undergoes projection and rasterization to create multiple 2D maps for the same level [1] - The method analyzes inter-floor connections and structural features to generate an inter-floor connection map [1] - Topological path searching is conducted based on the inter-floor connection map and 2D same-level maps to derive the optimal planning path [1] Group 3: Application - The invention enables accurate navigation for robots within multi-floor environments of the same building [1]
