[Diffraction Limited] has been working on a largely 3D-printed micropositioner for some time now, and previously reached a resolution of about 50 nanometers. There was still room for improvement, ...

The synthesis of four‐bar mechanisms and the generation of precise motion have long been central to advancements in mechanical design. Recent progress has integrated advanced optimisation algorithms, ...

There’s seldom anything as joyful and relaxing to watch as a simple marble run. Of course, the thing about letting marbles fall under gravity is that you eventually need to lift them back up again.
