Below you will find ten different options for controlling linear actuators. This list is intended to give you an overview of what's possible for linear actuator control. It's not exhaustive, there are other options, but these are the ones that will work for most people.
Rutgers University-New Brunswick engineers have discovered a simple, economical way to make a nano-sized device that can match the friendly neighborhood Avenger, on a much smaller scale. Their creation weighs 1.6 milligrams (about as much as five poppy seeds) and can lift 265 milligrams (the weight of about 825 poppy seeds) hundreds of times in a row.
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™ Solution eliminates downtime, loss of revenue, expensive cable and hose replacement costs, maintenance labor 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.
REIKU is committed to providing the most modular, effective options for ensuring your robotic components operate without downtime due to cable management.
