The quadruped robot controller is a dedicated controller specifically designed for quadruped robots. It integrates 3D SLAM and GNSS RTK tightly coupled algorithms, enabling high-precision positioning and autonomous navigation functions both indoors and outdoors as well as in open spaces. It can precisely control the walking posture and movements of the robot in complex terrains, whether it is climbing, crossing obstacles, or moving in narrow spaces. Through graphical programming, it supports secondary development, quickly integrates gas detection and other sensors, and uploads data to the cloud platform. It is compatible with mainstream quadruped robot bodies such as Yushu and Yun Cui Shen, integrates SDK to achieve quick deployment out of the box, and also supports automatic cross-floor operations.
