Abstract
In a manufacturing plant, the various parts are transported or assembled by industrial robots. Because these robot has a special robotic hand for a part, there are the problems of exchange time of hand and cost of development and storage of hand. These problems are solved by universal hand which can grip the parts with various shape, size and weight. We previously proposed the vacuum gripper imitating octopus sucker. This gripper can absorb the flat, curvature, and uneven surface. The purpose of this study is the fabrication of the gripper with micro protrusions imitating denticles on an octopus sucker, which has the effect of enhancement of absorption force. The diameter and height of denticle were 2 μm and 1 μm, respectively. The adsorption force was improved, since the denticles are arranged on the gripper.
