Inflatable deployable netted grab with ejection function

By designing an inflatable, deployable rope net gripper, and utilizing a combination of a base, finger rods, an elastomer for extending the fingers, and an active control rope, the problem of damage when gripping irregularly shaped or fragile objects by traditional grippers is solved. This enables rapid adaptation to gripping different objects, improving gripping efficiency and flexibility.

Abstract

The application discloses an inflatable and deployable rope net gripper with a shooting function and belongs to the technical field of robot grippers. The gripper comprises a base, elastic body folding and unfolding fingers fixed on the fingers rods around the base, head clamps fixed on the heads of the four elastic body folding and unfolding fingers, elastic belts installed between the opposite two elastic body folding and unfolding fingers, clamps fixed at the middle positions of the elastic belts, first active control ropes capable of being tightened or released fixed at the lower ends of the clamps, second active control ropes connected between the four elastic body folding and unfolding fingers, the second active control ropes penetrating through the through holes at the ends of the elastic body folding and unfolding fingers and the through holes on the fingers rods to form a net structure, and the opening width and depth of the rope net gripper are controlled by adjusting the inflation pressure combination of the first and second active control ropes and the four elastic body folding and unfolding fingers, so that objects with different shapes and sizes are gripped, released and shot.
