A new linear/rotary dual-motion actuator has been designed to provide incremental rotational and linear movement of the output shaft. The Size 14 actuator has two degrees of freedom of movement that ...

For a motor to power machinery, the local motion has to be translated into the ordered movement of other parts of the system. Organic chemists have now produced a light driven rotary motor in which ...

Consider a world composed of nanometre-sized factories and self-repairing molecular machines where complex and responsive processes operate under exquisite control; where translational and rotational ...

Biological rotary motors can alter their mechanical function by changing the direction of rotary motion. Achieving a similar reversal of direction of rotation in artificial molecular motors presents a ...

Light-driven molecular motors were first developed nearly 25 years ago at the University of Groningen, the Netherlands. This resulted in a shared Nobel Prize for Chemistry for Professor Ben Feringa in ...

Motion-control or industrial automation system designers who need to measure the rotation of shafts or other mechanical components can typically choose from two types of rotary encoders. Encoders ...

RC servos are handy when you need to rotate something. You can even modify them to rotate continuously if that’s what you need. However, [Roger Rabbit] needed linear motion, but wanted the simple ...

On Jan. 28, 1919, 25 men gathered in the St. Charles Hotel in downtown Cape Girardeau to be initiated into a brand-new Rotary Club -- the first such club in Southeast Missouri. The Rotary movement had ...

Researchers have developed a prosthetic joint that connects directly to the forearm bones of an amputee, allowing them to use a prosthesis with a wrist-like rotary movement. Use of the new joint could ...
