New robotic 'muscle' is a thousand times stronger than a human's and capable of hurling an object 50 times heavier than itself

If mankind does ever become embroiled in a Terminator-style 'war against the machines', we're really going to have to start doing a few more press-ups.

Researchers have developed a robotic muscle, an incredible thousand times more powerful than that of a human and capable of hurling an object 50 times heavier than itself.

The breakthrough relies on a material called vanadium dioxide which has a unique ability to change its size, shape and structure when heated.

Robo muscle: The 'micro-bimorph dual coil' developed by U.S. scientists that can hurl an object 50 times heavier than itself

A team at the Lawrence Berkeley National Laboratory in U.S. have used vanadium to build a torsional motor which works just like a human muscle, except it is far faster and more powerful.

The vanadium muscle is capable of catapulting extremely heavy objects over five times its own length in just 60 milliseconds.

But there's no need to worry about hoards of Herculean robots rising up and taking over the world just yet, the proto-type robo muscle is only micro-sized.

Study leader, Junqiao Wu told nanowerk.com 'We've created a micro-bimorph dual coil that functions as a powerful torsional muscle, driven thermally or electro-thermally by the phase transition of vanadium dioxide.

'Using a simple design and inorganic materials, we achieve superior performance in power density and speed over the motors and actuators now used in integrated micro-systems.'

What makes Vanadium dioxide so unique is that it is an insulator at low temperatures but becomes a conductor when it hits 67C, a bit like plastic transforming into metal.

The scientists hope that this remarkable ability can be harnessed to create far more energy efficient electronic and optical devices.

When heated, vanadium dioxide crystals change their structural form rapidly, both contracting and expanding at the same time. It is this particular trait that the researchers have harnessed to create the robo-muscle.

Dr Wu explains: 'Multiple micro-muscles can be assembled into a micro-robotic system that simulates an active neuromuscular system.

'The naturally combined functions of proximity sensing and torsional motion allow the device to remotely detect a target and respond by reconfiguring itself to a different shape.

'This simulates living bodies where neurons sense and deliver stimuli to the muscles and the muscles provide motion.

'With its combination of power and multi-functionality, our micro-muscle shows great potential for applications that require a high level of functionality integration in a small space.'

This is actually a very important discovery - for the military!

Scientists created a 'RoboBee':

A winged robot the size of a housefly has taken its first controlled flight.

Dubbed the 'RoboBee', the tiny 80 milligram device has a pair of buzzing fly-like wings that flap 120 times a second.

The robot, developed over 10 years, is the first working model of a flying insect.

Now add the new 'strength' that this discovery would give these Drones, they would have the ability to fly further and carry payloads - a weapon?

Probably some kind of sting - which kills.

Imagine a swarm of these things released against 'enemies' of those that control them?

Good for crowd control.

A major problem was finding a way to move the wings.

'Large robots can run on electromagnetic motors, but at this small scale you have to come up with an alternative, and there wasn't one,' said co-researcher Kevin Ma, from Seas.


Well, no problem now, is there........... :think:

:cheers:

I believe the robotic bees are being developed to replace bees for pollination if/when the time comes.

We all know what happens when bees are no more don't we?

The Bees have more chance of survival than us humans do but that is my opinion

WOW! This Is Going To Change Our Lives In Ways We Can’t Even Imagine! REVOLUTIONARY!!!

Scientists create Terminator-style muscle at 1,000 times human strength

Image

American scientists have developed a robotic muscle 1,000 times more powerful than a human’s – using a revolutionary material that fluidly changes its properties.

The invention gives vanadium dioxide amazing, superhero-style powers. Its most striking property is to change shape and structure whenever differing amounts of heat are applied to it.

This made it perfectly suited for creating a torsional motor muscle, as researchers at the US Department of Energy’s (DOE) Lawrence Berkeley National Laboratory have found, the Lab’s website reported.

Added to this is the material’s capacity for changing size and other physical characteristics. And when made into a robotic muscle, its estimated strength equals to hurling objects 50 times its weight and five times its length at speeds as fast as 60 milliseconds.

Team leader on the study, Junqiao Wu, said in Berkeley Lab’s statement that they have “created a micro-bimorph dual coil that functions as a powerful torsional muscle, driven thermally or electro-thermally by the phase transition of vanadium dioxide.”

Wu, who is a member of both Berkeley Lab and the Berkeley University’s Materials Science and Engineering department, co-authored the research submitted to the journal Advanced Materials, entitled “Powerful, Multifunctional Torsional Micro Muscles Activated by Phase Transition.”

Vanadium dioxide is not a new material to the electronics industry, already receiving praise for its ability to be both an insulator (at low temperatures) and a conductor (whenever the temperature is raised to above 67 degrees) undergoing what scientists call a temperature-driven phase transition. They say that more energy-efficient optical and electronic devices are definitely in the cards.

And that is not all. For when heated, vanadium dioxide’s crystals begin to rapidly contract along one dimension, while expanding along the other two, showing that a structural phase transition effected by temperature changes is also taking place. This physical property means that in future, using the material for anything from artificial muscles to robotic technologies and complex machinery is practically a given.

As Wu explains, “miniaturizing rotary motors is important for integrated micro-systems and has been intensively pursued over the past decades… the power density of our micro-muscle in combination with its multi-functionality distinguishes it from all current macro- or micro-torsional actuators/motors.”

This opens doors for scientific progress being made almost exponentially, as a series of micro-muscles could be used to build a more complex organism – perhaps even simulate an active neuromuscular system, due to the material’s miraculous property of “proximity sensing and torsional motion [which] allow the device to remotely detect a target and respond by reconfiguring itself to a different shape,” Wu says. “This simulates living bodies where neurons sense and deliver stimuli to the muscles and the muscles provide motion.”

However researchers say it is a little too early to start fearing a Terminator-style rise of the machines, as the mechanism in question is currently the size of a microchip.
