Armed with even with the most-sophisticated motion controller, engineers can still find it difficult to attain precise linear motion unless the mechanical components are appropriately designed for the ...

Linear motors and ball-screw drives seem to hog the limelight when it comes to linear motion. Rack-and-pinion drives, another type of linear motion device, get no respect. But they are perfectly ...

Vibrots are tiny devices that convert linear vibrations into rotational motion and are of great interest to scientists studying the collective motions of particles in physics, biology and chemistry.
