Insect-size drones are too small to lug around complex navigation systems. To help tiny autonomous fliers find their way home ...

Photon-driven nanorobots can steer, capture, and move bacteria with precision, enabling controlled manipulation in microscopic environments and offering new tools for microbiology.

The newest generation of microrobots is so small that a single unit can perch on the ridge of a fingerprint and practically vanish from sight. Built at a scale that rivals grains of salt and human ...

For decades, microscopic robots lived mostly in our imagination. Movies like "Fantastic Voyage" convinced us that tiny machines would one day cruise through the human body, fixing problems from the ...

Researchers in Finland have developed small, fairy-like robots that can fly, which could help to pollinate vital crops across the globe. Created at Tampere University, these tiny robots are made of ...

Tiny magnetic bots that are activated by light can clear bacterial infections deep in the sinus cavities, then be expelled by blowing out the nose. Sinusitis is a common respiratory condition often ...

Scientists turned simple knots into tiny robots that jump, spin, and plant seeds, offering a new tool for ecosystem restoration.

Tiny surgical robots are learning to make decisions inside the human body, using AI to interpret complex biological environments in real time. Unlike traditional minimally invasive procedures, where ...

Most robots depend on controlled environments, because the real world is hard to get around in. The smaller the robot, the bigger this problem because little wheels (or legs) can take only little ...

Scientists have created what they say is the world's smallest untethered flying robot, by taking a unique approach to its design. To minimize size and weight, they've moved the bot's power and control ...
