Research on Rapid Construction Method of Kinematics Coordinate System from a New Kind of Mobile Robot

Abstract

Abstract:

A redundant coordinate system was proposed firstly，and the details about how to construct the redundant coordinate system and how to use the redundant coordinate system were listed effectively, and the results of the analysis process were simulated.The simulated results suggest that the method used above is efficient and correct.To study how to solve the serial robot kinematics quickly, the kinematics coordinate system was transformed by Y axis, and the computed results show that transforming the kinematics coordinate system by Y axis can solve the kinematic model quickly and efficiently. The computed results suggest that constructing the redundant coordinate system and transforming the kinematics coordinate system by Y axis can solve the serial robotic kinematics efficiently.
