Adjusting parameters of a dynamical robot model

摘要

A method, robot arrangement and computer program product for tuning a dynamical model of an industrial robot on a foundation. The parameter determining device includes a model memory with a first dynamical model of the robot, the first dynamical model including first model parameters representing dynamical properties of the robot; and a second dynamical model of a foundation to which the robot is to be attached, the second dynamical model including second model parameters representing dynamical properties of the foundation, and a parameter adjusting unit that obtains information about dynamical properties of the foundation by ordering the actuator to move the robot and by receiving, from the detector, measurements of at least one property affected by the movement; and set at least one of the second model parameters on the basis of the dynamical properties of the foundation.
