DARPA Funded Artificial Muscles Allows Robots to Lift 1,000 Times their Own Weight

The United States’ military’s unrelenting quest to deploy new technologies that make its soldiers stronger and tougher has led to the development of artificial muscles that can carry up to 1,000 times their own weight.

Washington DC, United States (4E) – The United States’ navy’s unrelenting quest to deploy new applied sciences that make its troopers stronger and more durable has led to the event of synthetic muscle tissue that may carry as much as 1,000 occasions their very own weight.

The U.S. Defense Advanced Research Projects Agency (DARPA) is funding a program that has led to the event of an affordable new materials enabling machines to carry out smoother, much less inflexible and extra human-like actions. The program additionally includes the National Science Foundation and the Wyss Institute for Biologically Inspired Engineering at Harvard University.

Experts mentioned the event of those new “artificial muscle-like actuators” is a leap ahead within the area of sentimental robotics. The breakthrough was made by researchers on the Massachusetts Institute of Technology.

The actuators are constructed on a framework of steel coils or plastic sheets. Each muscle prices just some $1 to make.

Inspired by origami (the Japanese artwork of paper folding), the actuators are so robust a synthetic muscle-like actuator weighing simply 2.6 grams can elevate an object weighing three kilograms (6.6 lbs), which is the equal of a duck lifting a automobile.

These synthetic muscle tissue can contract to 10 p.c of their unique dimension however can generate about six occasions extra power per unit space than mammalian skeletal muscle can. They’re additionally extremely light-weight.

The vacuum-based muscle tissue have a decrease danger of rupture, failure, and injury, and so they do not develop once they’re working, to allow them to be built-in into closer-fitting robots on the human physique.

“Artificial muscle-like actuators are some of the necessary grand challenges in all of engineering,’ mentioned Rob Wood, professor of engineering and utilized sciences at Harvard University, and a co-author of the research revealed within the peer-reviewed journal, the Proceedings of the National Academy of Sciences.

“Now that we have created actuators with properties similar to natural muscle, we can imagine building almost any robot for almost any task.”

Their origami inspiration derives from a zig-zag construction that a few of the muscle tissue use. This zig-zag construction permits them to contract and develop as commanded, utilizing vacuum-powered air or water stress.

The skeleton could be an origami-like folded construction, a spring or any strong construction with hinged or elastic voids.

“It’s like giving these robots superpowers,” mentioned senior creator Daniela Rus, a professor engineering and laptop science at MIT.
