The current method of scallop fishing is mainly Scallop Dredge. When sand at sea bottom enters a scallop during harvesting, none of the scallops can be sold for raw. Additionally, Scallop Dredge harvests a scallop with marine sources such as other shells. To avoid these problems, this study proposes a new harvesting method using a robot arm. The new method can catch the only scallop without entering sand in a scallop. the new method needs a gripper to attach a gripper to a robot arm. This study focuses on the phenomenon of adsorption by negative pressure and tries to develop a negative pressure adsorption gripper for scallop harvesting. an experiment gripping a scallop with the gripper of this study was successful.
