The configuration of a rigid mobile robot is usually described in 6 variables: his three-dimensional Cartesian coordinate system, and the relative external coordinate system of three Euler angles (RPY roll, pitch, yaw), so in the plane environment generally with three variables can be described, called posture.So in general, the posture information of a robot is a two-dimensional planar coordinate (x, y) of a robot and its azimuth Θ\theta, which is represented by this vector:⎛⎝⎜xyθ⎞⎠⎟\begin{pmat
