Table of Contents
Researchers at Cornell University have achieved a groundbreaking feat in robotics: the creation of the world’s tiniest walking robot, measuring a mere 2 to 5 microns. This revolutionary device promises to reshape the landscape of microscopy and micro-scale measurement technologies.
The robot’s minuscule size allows for unprecedented interaction with visible light waves,a capability unavailable to larger robots.This opens doors to capturing images and measuring forces on the smallest structures imaginable.
“This robot allows imaging in a way that ordinary microscopes cannot,” explained Paul mceuen, Professor Emeritus of Physical Sciences at Cornell University, in a statement released December 16, 2024. He further added, “this robot can move independently which allows more accurate and effective close-range imaging at the micro scale.”
Microscopic Marvel: How Does It Move?
A study published in Science on November 28, 2024, detailed the robot’s innovative movement mechanism.Utilizing visible light diffraction—the bending of light as it passes through small openings—the robot achieves highly accurate measurements. its minuscule size allows direct interaction with light, a unique advantage over conventional robots.
“These robots are the smallest ever, and we can control them with magnetic fields,” stated Itai Cohen, Professor of Physics at Cornell and a co-author of the study. the robot’s size dwarfs previous record-holders, which ranged from 40 to 70 microns.
The robot’s locomotion is achieved through a controlled magnetic field, creating a pincer-like movement that enables it to walk on surfaces and even “swim.” This autonomous movement capability is a meaningful advancement in robotics.
Furthermore, the researchers employed nanometer-scale magnetic patterns on the robot’s surface, manipulating its movement with magnetic fields. these patterns, either long and thin or short and fat, allow for precise control. ”This way, we can control the robot by using a larger or smaller magnetic field, depending on the shape of the magnet,” cohen explained.
Beyond Movement: High-Resolution Imaging and Force Measurement
The robot’s ability to manipulate light extends beyond movement. Its diffraction properties allow it to function as a microscopic lens, enabling high-resolution imaging at the microscale. Francesco Monticone, Associate Professor of electrical and Computer Engineering at Cornell University, noted, “By manipulating light, these robots not only move but also shape and control light in very detailed ways.”
In addition to imaging, the robot can measure forces. Its pincer movement allows it to squeeze objects, altering the light diffraction pattern. “We can measure these pattern changes with high accuracy. The robot functions like an elastic spring, measuring forces in a very sensitive way,” Cohen clarified.
this miniature marvel represents a significant leap forward in nanotechnology, with potential applications spanning various scientific fields and promising advancements in medical technology and materials science.
