Surface-adaptive robotic gripper

Robot gripper with surface-adaptive capability using vacuum suction modules and wire tension control

This technology is a robot gripper mechanism that connects vacuum suction modules via a chain-structured linkage arm and adapts to the surface shape of an object by adjusting the arm's configuration through a wire tension control unit.

In environments such as logistics terminals where the shape, material, and volume of objects are not standardized, fixed-form grippers have struggled to provide stable grasping.

This technology features a structure that varies the gripper's shape to fit an object's surface by controlling the curvature of the arm using multiple gripping modules, chain-structured connecting links, wires, winding rollers, and sliding tension-adjusting pulleys. It can be applied to logistics picking, service robots, and manufacturing automation, allowing for the stable grasping of various objects with different specifications without the need for gripper changes.

Key Features:

• A first upper wire guide member provided in a tube structure, coupled to the top of one of the plurality of first connecting links and having a hole penetrating in the front-to-back direction
• A surface-adaptive robot gripper including a first lower wire guide member provided in a tube structure with a hole penetrating in the front-to-back direction.
• A first adaptive gripping module positioned in front of the main gripping module, designed to suction and grasp objects using negative pressure
• The first connecting arm consists of a plurality of first connecting links connected in a chain structure
