We studied adhesion force of a suction cup which can be changed its rigidity during adhesive process. We figured out suction cup with high Young's modulus can generate high adhesion force, but on the other hand suction cup with high Young's modulus needs high pushing force. Therefore, we designed Young’s modulus of a suction cup to be low during pushing and high during pulling. Shape memory polymer which can change Young's modulus with temperature is used for changing the rigidity of suction cup. Then, we measured adhesion force for different temperature of shape memory polymer at the time of pulling. As a result, we achieved a 22% increase in adhesion force by changing rigidity of suction cup.
