Some DNA molecules may serve as handy micromachines to convert rotational motion into linear translation, an important function for positioning minuscule parts in microscopic devices. Researchers at ...

Nanomotors are capable of self-propelled directional motion driven by chemical fuels or other energy sources. They are the principal tools for active bottom-up control of motion in the molecular world ...

A cam is a rotating piece that converts rotary motion into reciprocating motion in the follower. Think of it like a spinning shape pushing something up and down. Eccentric/off centre cam: this is the ...
