Artificial muscle for soft robotics: Low voltage, high hopes

Phys.org:  Soft robots do a lot of things well but they're not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are slow to respond and difficult to store.

Dielectric elastomers, soft materials that have good insulating properties, could offer an alternative to pneumatic actuators but they currently require complex and inefficient circuitry to deliver high voltage as well as rigid components to maintain their form—both of which defeat the purpose of a soft robot.

Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a dielectric elastomer with a broad range of motion that requires relatively low voltage and no rigid components. They published their work recently in Advanced Materials.  Cont'd...

REIKU's Cable Saver™ - The Most Versatile Modular Robotic Cable Management Solution

REIKU's Cable Saver™ - The Most Versatile Modular Robotic Cable Management Solution

REIKU's Cable Saver™ Solution eliminates downtime, loss of revenue, expensive cable and hose replacement costs, maintenance labour costs. It's available in three sizes 36, 52 and 70 mm. All of the robots cables and hoses are protected when routed through the Cable Saver™ corrugated tubing. The Cable Saver™ uses a spring retraction system housed inside the Energy Tube™ to keep this service loop out of harms way in safe location at the rear of the Robot when not required. The Cable Saver™ is a COMPLETE solution for any make or model of robot. It installs quickly-on either side of the robot and has been tested to resist over 15 million repetitive cycles.
