Abstract: A method of payload estimation and a robot arm system and an electronic device using the same are disclosed for acquiring inertial parameters of a payload. The method comprises calculating a payload mass, merely rotating a forth joint of the robot arm system to calculate an equivalent moment of inertia of the payload, merely rotating a second joint to measure data for dynamic equations of a fourth joint, repeating at least two times to obtain at least two sets of the dynamic parameters to calculate a center of mass of the payload, and substituting the payload mass, the equivalent moment of inertia and the center of mass into an equation of parallel axis theorem to obtain a moment of inertia of the payload. The center of mass is calculated by solving two dynamic equations associated with the fourth joint, thus the computation complexity of the payload inertial parameters is reduced.
