In this study, we evaluated the suction forces of an elliptical micro suction cup array. The three directional suction forces were compared between the elliptical micro suction cup array and a circler micro suction cup array. In the elliptical micro suction cup array, the ratio of the suction force in the long axis direction to the suction force in the short axis direction was different by 1.7 times when the attaching force was 2 N. In contrast, the ratio in the circular micro suction cup array was almost same. It was confirmed that the suction force of the elliptical micro suction cup array changes depending on the direction of the applied force.
