Researchers from the Mbadachusetts Institute of Technology (MIT)) created artificial and cheap muscles for robots -as seen in this illustration- that give them the power to lift up to 1,000 times their own weight

Inspired by the technique of folded origami, US researchers UU They said on Monday that they created cheap and artificial muscles for robots that give them the ability to lift up to 1,000 times their own weight.

The breakthrough offers a leap forward in the field of soft robotics, which is rapidly replacing a previous generation of robots that were abrupt and rigid in their movements, the researchers say.

"It's like giving these robots superpowers," said lead author Daniela Rus, professor of electrical engineering and computer science at the Mbadachusetts Institute of Technology (MIT). 19659008] The muscles, known as actuators, are built on a frame of metal coils or plastic sheets, and each muscle costs about $ 1, said the report in the Proceedings of the National Academy of Sciences, a US journal reviewed by couple

Its origami inspiration is derived from a zig-zag structure that employs some of the muscles, which allows them to contract and expand as ordered, using air or pressure water pressure.

"The skeleton can be a spring, folded origami type structure, or any solid structure with articulated or elastic holes," says the report.

Possible uses include habitats of expandable space on Mars, miniature surgical devices, wearable robotic exoskeletons, offshore exploration development, or even transformable architecture.

"Artificial muscle-like actuators are one of the most important challenges in all engineering," said co-author Rob Wood, professor of engineering and applied sciences at Harvard University.

Now that we've created actuators with properties similar to those of natural muscle, we can imagine building almost any robot for almost any task. "

Researchers constructed dozens of muscles using metal springs, foam or plastic in a variety of ways. shapes and sizes

They created "muscles that can contract up to 10 percent of their original size, lift a delicate flower from the ground and coil into a spiral, all simply sucking the air from them," the report said. [19659008] Artificial muscles "can generate about six times as much force per unit area as the skeletal muscles of mammals and are also incredibly light," he added.

A .09-ounce muscle (2.6 grams) can lift an object that weighs 6.6 pounds (three kilos) ams) "which is the equivalent of a mallard raising a car."

According to co-author Daniel Vogt, an engineer Research at the Wyss Institute, vacuum-based muscles "have a lower risk of rupture, failure and damage, and do not expand when they are functioning, so you can integrate them into tighter robots in the human body."

The research was funded by the Defense Advanced Research Projects Agency (DARPA), the Science Foundation and the Wyss Inspired Biological Engineering Institute.
