Abstract: Millimeter-scale mechanisms, from novel actuators and sensors to insect-inspired flying vehicles, have applications in medical devices, infrastructure inspection, small satellites, and more.

DARPA recognizes that insect-scale flying robots have immense military potential. In laboratories around the world, engineers are racing to shrink robotics into microscopic proportions, many examples ...

While that scale B-52 might be the biggest, it’s far from the only model airplane taking advantage of those tiny jet engines for modelers. This beautiful Concorde model (with working subsonic nose ...
