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 strain. 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 named “GRIP-tape,” the phrase GRIP standing for “Greedy and Rolling In-Aircraft.” It grasps objects of assorted sizes and styles between two grippy however compliant triangular fingers.
Every of these fingers is made 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 kind 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 Selecting
By various the course wherein every of the 4 reels (two per finger) rotate relative to at least one one other, the fingers will be made longer or shorter, they will rotate an merchandise grasped between them, or they will draw that merchandise in or out, conveyor-belt-style. The complete gripper may also roll backward and forward and tilt up and down, swiveling on its robotic wrist.
It’s hoped that after the expertise is developed additional, it could possibly be utilized in fields akin to agriculture, for selecting vegetables and fruit with out damaging them. In reality, UCLA’s EEWOC (Prolonged-reach Enhanced Wheeled Orb for Climbing) robotic already makes use of a measuring-tape-based magnetic limb for climbing metallic buildings.

”We wish to search for non-traditional, non-intuitive robotic mechanisms,” says Gravish. “The tape measure is such an exquisite construction due to its mixed softness and stiffness collectively.”
A paper on the research was lately printed within the journal Science Advances.
