Abstract: Disclosed herein is a shape compliant electroadhesive gripper for picking up an atypical object. The shape compliant electroadhesive gripper comprises a body, and an electroadhesive module disposed on the body and including an electrorheological elastomer, wherein, when a voltage is not applied, a shape of the electroadhesive module is deformed according to a shape of an external object coming into contact with the electroadhesive module, and when the voltage is applied, rigidity of the electrorheological elastomer is increased to maintain the shape of the electroadhesive module, and when the voltage is applied to the electroadhesive module, electroadhesion is made due to an electrostatic force generated between the electrorheological elastomer and the adjacent external object.
