According to Katia Bertoldi, professor of applied mechanics and senior researcher of the paper, "these all-terrain soft robots could one day travel across hard environments for exploration, inspection, monitoring and search and rescue missions or perform complex, laparoscopic medical procedures".
Robots take on all forms these days, and now, there's a robot that takes cues from snake skin.
Kirigami is a three-dimensional paper cutting method. The SEAS team applied the principles of kirigami to locomotion to enable their robot to move.
"We designed highly stretchable kirigami surfaces in which mechanical instabilities induce a transformation from flat sheets to 3D-textured surfaces akin to the scaled skin of snakes", the study published on Robotics Science magazine read.Читайте также: DPRK general plans to attend Pyeongchang closing event
To build their robot, the researchers started from scratch with a basic sheet of plastic. It was used to cover a tube-like actuator made out of rubber-like material which can expand like a balloon.
When switched on, the robot is able to crawl forward by expanding and contracting, and the tiny cuts on its skin pop out and then grip the ground to propel it forward each time the actuator expands. Of all the shapes they tried, the researchers found that the trapezoid-shaped cuts were the most effective because they gave the robot the greatest stride.
Robots come in all shapes and sizes, and while robotics experts are often inspired by nature when designing new bots, you probably wouldn't think a snake would provide much inspiration. Snake skin is covered with tons of interlocking scales, and the special scales beneath them cling to the ground and push the animal forwards or backwards through friction as muscles expand and contract.При любом использовании материалов сайта и дочерних проектов, гиперссылка на обязательна.
