Abstract
A method assesses a state of at least one axial joint of an industrial robot, on the basis of data of a mechanical backlash present at the axial joint of the industrial robot, a state of wear of the axial joint being determined. On the basis of data of a torque profile, a first loading state of the axial joint is determined at the axial joint during at a first working cycle of the industrial robot. On a basis of data of a movement sequence at the axial joint during a second working cycle of the industrial robot, a second loading state of the axial joint is determined. An assessment of the state is carried out by pre-assessing the state of wear, the first loading state and the second loading state and a subsequent comparison with an empirically obtained comparison value matrix.
