Metal measuring tape is an attention-grabbing materials, in that it is inflexible sufficient to carry its form when prolonged, however versatile sufficient that it provides means beneath stress. Scientists have taken benefit of that twin nature in a intelligent new robotic gripper designed for dealing with fragile gadgets.Created by Assoc. Prof. Nick Gravish and colleagues at UC San Diego, the mechanical appendage is called “GRIP-tape,” the phrase GRIP standing for “Greedy and Rolling In-Airplane.” It grasps objects of varied sizes and shapes between two grippy however compliant triangular fingers.Every of these fingers is fabricated from a few lengths of measuring tape that are laid lengthwise one on prime of the opposite, and adhesive-taped collectively in that configuration … so that they type a single two-layered ribbon that is bent/buckled on the tip of the finger. Two motorized reels – one at both finish of that ribbon – roll it in and spool it out as wanted.
A New Robotic Gripper Based mostly on Measuring Tape is Sizing Up Fruit and Veggie Choosing
By various the course during which every of the 4 reels (two per finger) rotate relative to at least one one other, the fingers might be made longer or shorter, they’ll rotate an merchandise grasped between them, or they’ll draw that merchandise in or out, conveyor-belt-style. The whole gripper may also roll back and forth and tilt up and down, swiveling on its robotic wrist.It’s hoped that after the know-how is developed additional, it might be utilized in fields similar to agriculture, for selecting vegetables and fruit with out damaging them. Actually, UCLA’s EEWOC (Prolonged-reach Enhanced Wheeled Orb for Climbing) robotic already makes use of a measuring-tape-based magnetic limb for climbing steel buildings.

”We wish to search for non-traditional, non-intuitive robotic mechanisms,” says Gravish. “The tape measure is such a beautiful construction due to its mixed softness and stiffness collectively.”A paper on the research was lately printed within the journal Science Advances.Supply: College of California, San Diego
