Abstract
The present application provides a kinematics modeling method, apparatus and device for a multi-degree-of-freedom mechanism and a storage medium. The method includes: constructing a point coordinate system, and constructing the transformation matrix; constructing transformation matrices of two rotating axes and the transformation matrix; constructing the forward kinematics model based on the transformation matrices of the point coordinate system, the two rotating axes and the workpiece coordinate system; solving the motor value of the rotating axis through the rotation matrix of the end-effector, using the translation matrix of the end-effector as a non-homogeneous linear equation set, solving the motor value of linear axis. Thus solving the technical problem in the prior arts that the redundant parameters are introduced as a cost to separate the linear axis and the rotating axis for step-by-step kinematics calibration, which affects the error calibration precision of the overall end-effector movement of the mechanism.
