Abstract: A method and a damping device for absorbing an undesired vibration, in particular, a tremor or an oscillation, in which a base is decoupled from the vibration by a positioning actuator. A control unit registers a relative displacement of the foot and a mass caused by the vibration as a deflection of a spring element that links the foot to the mass.
