A spiral air gripper is a pneumatic robot gripper that coils an expandable tube around objects of variable shapes. The elastic tube is covered by an extensible fabric, which restricts the expansion of the diameter when the elastic tube elongates due to the inside air pressure. The expandable tube of the coil-shaped gripper is enlarged by approximately three times the diameter of the coil when the inside air pressure of the tube is increased. By releasing the inside air, the diameter of the coil is reduced, and it wraps itself around objects tightly. This simple structure makes it easy to develop grippers that can hold large objects, such as furniture.
