Vacuum (or active) suction cups with the clingfish-effect can adhere to even rougher, more structured, and more uneven surfaces than the passive suction cups with the clingfish effect. In industrial processing, they can extend the range of surfaces that can be transported. Moreover, these materials transported can be somewhat porous or permeable.
Items of all kinds of shapes and surfaces. Aside from all surfaces listed for the passive suction cups, for example, fruits such as oranges, apples, plums, lemons, peaches or pears (image 1-6), eggs (image 7), bottles (image 8), heavily structured metal (image 9), all kinds of wood (image 10), double-structured surfaces (image 11).
