Abstract
We proposed a gripper imitating the octopus sucker for universal gripper which can grip the various parts in production site. This paper described the gripper imitating a funnel structure of octopus in order to improvement of shape followability. The imitated structures were necking, radial trench and slope of sucker. We evaluated the pressing force for absorption, which the shape followability is high when the pressing force is low. The necking structure has an effect of decrease of the pressing force, since the sucker with neck was flexible. The radial trench has effect of increase of maximum absorption force of gripper, since the absorption area is increased.
