Afterwards, we propose a new constant coefficients measurement method in dynamic equation of robot manipulators, this measurement method includes three groups of experiments: group one, let each joint of robot manipulator keep static to measure the constant coefficients in gravity term of dynamic equation and Coulomb frictional torque, group two: let only one joint of robot manipulator move at a constant velocity to measure the viscous frictional coefficient and constant coefficients in effective inertia of dynamic equation, group three: let only one joint of robot manipulator move at constant acceleration at a time to measure constant coefficients in Coriolis and centrifugal term and coupling inertia of dynamic equation.

让操作器单个关节恒速运动，在对驱动系统中传动机构，减速装置和电感系数综合考虑的基础上，这组实验对粘滞摩擦系数及有效惯量中常数系数进行测量。这种测量方法只要求旋转关节的驱动电机施加恒定电压，回转关节驱动电机施加正弦波电压。3。让操作器单个关节恒加速运动，这组实验测量动力学方程中哥氏力、离心力项和耦合惯量项中的常数系数，这种测量方法只要求单个关节匀加速运动，而其它各关节保持静止，这种测量方法虽然要求关节匀加速运动，但不必进行关节角加速度检测，而只需进行关节角位移和角速度检测即可，输入量直接给定为输入电压。
