| Abstract: | Algorithm and mathematical model of identification for the inertial parameters of the end-effector of manipulator in a robot were analyzed. A new method of identifying inertial parameters which was different from traditional artificial neural network problems was developed, hence the physical meaning can be found from the structure and the weights of the networks. The difficulty of obtaining samples was resolved. General rules and advantages of application of artificial neural network in parameter identification of the system were investigated. This method is simple, direct and less in operation, which can be applied in on line identification of inertial parameters of the end-effector of a robot based on the signals of sensor. Feasibility and effectiveness of the method are proved by the results of experiment in a PUMA562 robot. |
