The versatile “fingers” on the tip of an elephant’s trunk have offered the inspiration for a flexible robotic gripper able to selecting up and holding onto quite a lot of objects each massive and small – from an acupuncture needle to a skinny metallic ruler to a big packaging field.
A bit like an enormous slinky coated in robust pores and skin and jam-packed with muscle tissues 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 dust, and familiarize yourself with different-shaped objects. It has 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 Equipment and Supplies (KIMM) seems to be one of the crucial 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 kind grabber, the machine is ready to pinch and grasp objects by way of smooth buildings on the tip.
Wires pushed by a pneumatic cylinder are fed throughout the middle of this smooth 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 power as mandatory.

This primarily signifies that the gripper can decide up objects of various shapes, sizes and weights – which the KIMM workforce demonstrated by grabbing a 0.25-mm-diameter needle plus a packing field that was 10 occasions its measurement. Different duties included gift-wrapping a doll, plonking candles on a cake earlier than lighting them utilizing matches and even participating in a spot of flower arranging.
“After contacting the smooth gripper to the ground after which making a vacuum whereas conducting a pinching movement, the gripper can grip objects as when you have been strongly pinching the ground along with your fingers,” mentioned the workforce’s Dr. Sung-hyuk Track. “On this manner, even very skinny objects may be simply gripped and be lifted from the ground.”
The researchers reckon that the system operates with no need a fancy sensors or controls, and the smooth gripper should not pose an damage danger when operated round folks. As such, future purposes for the know-how embody meeting bots on manufacturing strains and repair robots across the house.
“Not solely can it deal with objects of varied sizes, from tremendous components to containers, with out advanced mechanical buildings or sensors, but in addition it may be dealt with simply, which suggests it may be utilized to numerous industries in addition to each day life,” mentioned Dr. Chanhun Park, Director of the AI Robotic Analysis Division. “I count on it to be of nice assist to the event of service robots in each day life and corporations that produce quite a lot of completely different objects.”
