Abstract
The present disclosure is applicable to robot technology. A method for robot posture detection and a robot are provided. The method includes: obtaining a position parameter of each of nodes of a robot; obtaining a first weighted value of each of the nodes corresponding to the position parameter of the corresponding node; calculating a weighted value of each of body parts of the robot based on the first weighted value of the node of the corresponding body part; and correcting an original parameter of a center of gravity of the robot according to a body gravity center influence factor of each of the body parts, and the weighted value of each of the body parts.
