A dynamics model of a Six Degree of Freedom (6-DOF) sanitary ceramics glazing robot by using Newton-Euler method is established in order to improve the robot’s system stability.The influence of the end effector’s varied loading on moment of all articulated joints of a glazing robot was researched. The result of simulation shows changes of the end effector’s loading values and directions influence substantially on moment of three wrist joints, but influence slightly moment of the shoulder joint, the loin joint and the elbow joint. Moment of the shoulder joint, the loin joint and the elbow joint mostly depend on their own architecture. When the end effector’s loading is opposite direction of gravity, moment of wrist joint is reduced.
