Depending on the application scenario, robotic grippers are designed in various ways to meet specific needs. Existing robotic grippers generally include two-finger grippers, three-finger grippers, vacuum suction cups, and magnetic grippers. However, when dealing with large or complex materials, existing robotic grippers cannot hold the materials securely, and accidents such as material tilting, damage, or detachment can easily occur during material handling. This makes them inconvenient to use and unsuitable for automated production. Utility Model Content
