Super-stretchy wormlike robots susceptible of 'feeling' their surroundings could find applications successful manufacture and prosthetics, scientists say.
A squad of engineers from the University of Glasgow person developed robots with forms of question inspired by the movements of inchworms and earthworms.
The soft, wiggly roboworms tin agelong up to 9 times their ain magnitude and are susceptible of a signifier of proprioception—the method by which biologic organisms similar worms comprehend their presumption successful space. That ability, not demonstrated earlier successful the tract of brushed robotics, allows the robot worms to compression into choky spots that their conventionally rigid robot counterparts cannot reach.
The researchers anticipation that their breakthrough could pb to a caller procreation of robots susceptible of autonomously exploring difficult-to-reach places. They could find applications successful mining, operation oregon adjacent successful disaster relief to hunt for survivors trapped successful rubble.
Their exertion could besides beryllium utilized successful processing much lifelike prosthetics, oregon equipping robots with the quality to wrapper astir and assistance irregularly-shaped dense objects.
The improvement builds connected erstwhile probe from the University of Glasgow's Bendable Electronics and Sensing Technologies (BEST) group, which has recovered caller ways to embed flexible electronics into deformable surfaces.

That expertise has allowed them to physique intrinsic strain sensors into the wormlike robots, which astir 4.5 centimetres long. They are covered successful 'skin' made from a signifier of stretchy integrative called Ecoflex and a graphite paste developed by the team.
Tiny permanent magnets attached astatine either extremity of the robots' tubular bodies assistance them to determination on a metallic surface. The sensors successful their tegument assistance them 'sense' their movements successful narration to their bodies by measuring the electrical absorption of the graphite paste, which changes arsenic the robots' bodies expand. When the absorption reaches a preset maximum value, the assemblage contracts again, moving it forward.
Professor Ravinder Dahiya of the University of Glasgow's James Watt School of Engineering leads the BEST group, which developed the system.
Professor Dahiya said: "Proprioception is simply a captious diagnostic of galore forms of biologic life, and scientists person agelong been inspired to effort and make engineered systems which mimic this ability.
"Our bioinspired robots are a measurement towards creating soft, flexible robot systems susceptible of the infinite directions of question that quality has created successful inchworms and earthworms.
"The quality of brushed robots similar these to accommodate to their surroundings done seamlessly embedded stretchable sensors could assistance autonomous robots much efficaciously navigate done adjacent the astir challenging environments."
The team's paper, titled "Bioinspired Inchworm and Earthworm similar Soft Robots with Intrinsic Strain Sensing," is published successful Advanced Intelligent Systems.
