Will it be handling small batch products? Does the gripper need to have strength or a delicate touch? Does the gripper have to be certified food safe? Your choice of gripper should be guided primarily by the application you have in mind for your automation. When selecting a gripper, there are a few key considerations: In this article, we'll take a look at the some of the most common grippers. Robots from Universal Robots are compatible with virtually every gripper type, including those listed above. But for packaging and palletizing operations, where you need to stack boxes of product, a bulky gripper with large suction cups is probably the better choice. For direct handling of delicate foodstuffs, for example, a small, soft gripper is likely to be the best choice. The incredible variety of gripper types is due to the massive variety of objects robots can handle, from textiles to electronics components and automotive parts. And grippers receive their power in different ways, from electrical to pneumatic (air) and hydraulic (hydraulic fluid). Some grippers look like a soft round ball. Other grippers come with giant suction cups. Some grippers don't look like hands at all they look more like robot claws. Some grippers look just like hands, while others look like a hand with two or three fingers. Robot grippers don't get tired even when assigned tasks 24/7. Human hands are prone to error, especially when assigned to repetitive tasks. Grippers are also known as 'end-effectors' or 'manipulators.' And, at the end of the arm, robots are often fitted with what are called grippers – special devices designed to help robots handle objects in the real world. Industrial robot 'arms', as they are called, do have elbows and wrists. If you think of a simple industrial robot as consisting of an arm, with an 'elbow' and a 'wrist' for motion and a 'hand' for picking things up, you're not being childish –in fact, you're thinking like a roboticist.
