Grippers are mechanical devices designed to grasp and hold objects securely. They are commonly used in robotics and automation to enable machines to pick up, manipulate, and release items. Grippers can vary in design, including parallel grippers, which move two fingers in parallel, and angular grippers, which open and close at an angle. These devices can be powered by different mechanisms, such as electric motors, pneumatics, or hydraulics. Grippers are essential in various industries, including manufacturing, packaging, and logistics, where they enhance efficiency and precision in handling materials.
