Artificial Muscles

Shanghai robotics startup DroidUp has launched what it calls "a beautifully designed and expressive bionic robot" that is touted as "the world's first highly bionic robot that deeply integrates human aesthetics and advanced humanoid movement."

Engineers at MIT have devised an ingenious new way to produce artificial muscles for soft robots that can flex in more than one direction, similar to the complex muscles in the human body. It could soon unlock new capabilities for squishy bots.

Combining lab-grown muscle tissue with a series of flexible mechanical joints has led to the development of an artificial hand that can grip and make gestures. The breakthrough shows the way forward for a new kind of robotics.

While multi-material 3D printers do already exist, the filament they extrude is all one material at any one point in the printing process. A new system produces actual multi-material filaments, however, and they boast a very useful helical design.

We've been hearing a lot about "artificial muscles," which allow robotic devices to perform human-like motions. And while most of them have been produced in labs utilizing high-tech materials, a new type could be made by hobbyists using a 3D printer.

Researchers at ETH Zurich have developed a lightweight, wearable textile exomuscle that uses sensors embedded in its fabric to detect a user's movement intentions and chip in extra force as needed. Initial tests show a significant boost in endurance.

Researchers have developed a new type of artificial muscle that’s entirely made out of natural proteins. Responding to changes in its environment allows the muscle to flex on demand, which could make it useful for implants, prosthetics or robots.

"Muscle shirt" may soon take on a whole new meaning. A team has found a way to use bacteria to produce synthetic muscle proteins, which can then be spun into fibers to make clothing, protective gear and biomedical implants and prosthetics.

Soft-bodied robots move via pneumatic "muscles" that are selectively inflated or deflated. And while the muscles themselves may be soft and squishy, they're usually hooked up to hard, unwieldy pumps. A new pump, however, is both small and flexible.

If swarms of tiny robots are ever going to be used for purposes such as exploring disaster sites, then they'd better be rugged. A bot created at the EPFL research institute seems to fit the bill, as it can withstand being squished by a fly swatter.

We've watched with interest as subsequent developments have allowed RoboBee to fly, swim, hover, perch and lose its tether. Now it's become the first microrobot to achieve controlled flight using soft artificial muscles.

Researchers from the Department of Mechanical Science and Engineering at the University of Illinois have developed an artificial muscle made of carbon fiber and rubber that can lift over 12,000 times its own weight.
