Researchers have engineered a collective of small, modular robots capable of shifting between solid and fluid-like states to alter their collective shape, mirroring the advanced technology seen in the iconic T-1000 robotic assassin from “Terminator 2.”
From Science Fiction to Reality
A research team led by Matthew Devlin at UC Santa Barbara detailed these findings in a paper recently published in Science. The authors note that the vision of creating cohesive robotic collectives capable of morphing into virtually any form or adopting specific physical properties has remained a long-standing fascination for both the scientific community and the realm of fiction.
Biologically Inspired Engineering
Otger Campàs, a professor at the Max Planck Institute of Molecular Biology and Genetics, explained to Ars Technica that the development was heavily inspired by the behavior of embryonic tissues. To mimic these biological movements, the robots are equipped with motorized gears for internal navigation, magnets for structural cohesion, and photodetectors.
The photodetectors serve as a communication interface, allowing the units to receive complex instructions sent via a flashlight equipped with a polarization filter.
Overcoming Scaling Hurdles
Despite the breakthrough, Campàs emphasizes that the technology is currently “far from the Terminator thing.” The primary obstacles remain the physical size of the units and power constraints. The current iteration of the robots measures slightly over 5 centimeters in diameter, but the research team has set an ambitious goal to scale these units down to 1 or 2 centimeters—or potentially even smaller in future iterations.
