The variable stiffness suction pad can deform around the object. A few researches showed the grasping the rigid objects using the pad. The flexible pads became rigid on vacuum suction. We proposed the relationship between suction sequence and suction performance. We tested five suction sequences; the stiffness of pad is 1) harden before press on object, 2) harden after press, 3) harden with suction, 4) harden after suction, and, 5) flexible during operation. When the fabricated pad was the low stiffness in suction, the pad can grasp the uneven metal objects. The suction force of the sequence 5) was lowest in five suction sequences. In the sequence 3) and 4), the grasping performance was almost same. We have shown that the variable stiffness suction pad has the suitable suction sequence for the shape of object.
