Abstract in brief

This text explains how scientists use DNA origami to create tiny, nanoscale machines that can move in controlled and reversible ways, much like macroscopic mechanical devices.
They designed specific flexible and stiff DNA components to create joints that allow precise 1D motions, such as rotation and linear movement, which can be adjusted for flexibility and range.
By integrating multiple joints, they built complex mechanisms like a crankslider and a Bennett linkage that can change shape or position in 3D, which can be controlled and reversed by adding DNA input strands within minutes.
