Abstract
A motion target direction angle obtaining method and a robot using the same. The method includes: creating an absolute coordinate system, and obtaining an absolute position coordinate of at least one point after the first point in the absolute coordinate system; creating a relative coordinate system with the first point as an origin, and obtaining a relative position coordinate corresponding to the at least one point In the relative coordinate system; calculating matrix parameters of a transformation matrix based on the absolute position coordinate of the at least one point and the relative position coordinate corresponding to the at least one point; and determining a direction angle of the motion target at the first point based on the matrix parameters. Combines an absolute portioning method and a relative positioning method to calculate the direction angle.
