The versatile “fingers” on the tip of an elephant’s trunk have offered the inspiration for a flexible robotic gripper able to choosing up and holding onto a wide range of objects each massive and small – from an acupuncture needle to a skinny steel ruler to a big packaging field.
A bit like an enormous slinky coated in powerful pores and skin and jam-packed with muscle groups and nerves, an elephant’s trunk has many makes use of – packing a strong sense of scent, in a position to suck up water or grime, and become familiar with different-shaped objects. It’s been a supply of inspiration in robotics for a variety of years, having apparent purposes in pick-and-place operations, and the newest growth from researchers on the Korea Institute of Machinery and Materials (KIMM) appears to be like to be one of the vital succesful but.
Pitched because the “world’s first elephant-trunk-mimetic robotic hand,” and mixing the capabilities of a claw-type gripper with a suction sort grabber, the gadget is ready to pinch and grasp objects by way of tender constructions on the tip.
Wires pushed by a pneumatic cylinder are fed throughout the middle of this tender construction and alter the gripper’s form when activated, permitting its claws to partially fold in on themselves to pinch and seize objects, whereas embedded micro-channels create a vacuum seal to extend the gripping pressure as vital.

This basically implies that the gripper can choose up objects of various shapes, sizes and weights – which the KIMM crew demonstrated by grabbing a 0.25-mm-diameter needle plus a packing field that was 10 instances its measurement. Other duties included gift-wrapping a doll, plonking candles on a cake earlier than lighting them utilizing matches and even partaking in a spot of flower arranging.
“After contacting the tender gripper to the ground after which making a vacuum whereas conducting a pinching movement, the gripper can grip objects as should you had been strongly pinching the ground along with your fingers,” mentioned the crew’s Dr. Sung-hyuk Song. “In this fashion, even very skinny objects will be simply gripped and be lifted from the ground.”
The researchers reckon that the system operates without having a fancy sensors or controls, and the tender gripper should not pose an damage danger when operated round folks. As such, future purposes for the know-how embody meeting bots on manufacturing traces and repair robots across the dwelling.
“Not solely can it deal with objects of assorted sizes, from wonderful elements to containers, with out advanced mechanical constructions or sensors, but additionally it may be dealt with simply, which implies it may be utilized to varied industries in addition to each day life,” mentioned Dr. Chanhun Park, Director of the AI Robot Research Division. “I count on it to be of nice assist to the event of service robots in each day life and corporations that produce a wide range of totally different objects.”
