The current scallop fishing has some problems. The fishing can not harvest the natural scallops for raw consumption by the problems. To solve the problems, this study proposes a new method using a robot arm. The new method needs a gripper attaching a robot arm. From some demands that meet for scallops gripping, this research judge a suction gripper gripping with negative pressure is suitable to harvest the scallops. However, a suction gripper has disadvantages for gripping the scallops. Therefore, we develop a new gripper with a built-in spring to improve the disadvantages. Additionally, this study experiments with the developed gripper and evaluates the developed gripper.
