Researchers created a system that enables makers to incorporate sensors directly into rotational mechanisms with only one pass in a 3D printer. This gives rotational mechanisms like gearboxes the ...

Consider the mechanism shown below made up of a continuously-rotating input drive centered at C (shown on the right) and an output drive centered on O (shown on the left). A pin P is attached to the ...

Kaleidocycles are flexible polyhedral structures composed of rigid tetrahedra connected along their edges to form rotating ...

Consider the mechanism shown below made up of moveable links AB, BD and slider D. Link AB is rotating CCW at a constant rate. Point C is the center of rotation for BD, where point C is at the ...

Integrating sensors into rotational mechanisms could make it possible for engineers to build smart hinges that know when a door has been opened, or gears inside a motor that tell a mechanic how fast ...
