Patent number: 10981316Abstract: A control device for a handling device includes a storage medium, a processing unit, an output for outputting signals, and an input for receiving signals from the handling device. A waiting phase is conducted before an actuation of an end-of-arm tool mounted to an end-of-arm of a handling arm.
