Remote control Schematic showing (top panel) how microfibrebots can anchor to a blood vessel, navigate via helical propulsion, elongate to pass through narrow regions and aggregate to block blood flow ...

Researchers have created magnetically-controlled "sperm bots" that they can pilot around and monitor in real time. These tiny microrobots are bull sperm cells coated in magnetic nanoparticles.

New swarms of “ant-like” robots are able to lift heavy objects and hurl themselves over obstacles. The tiny magnetic automatons, developed by scientists in South Korea, work together like insects to ...

In one of the most surprising innovations in medical technology, scientists have created tiny, remote-controlled “sperm-bots” that could one day swim through the human body to deliver drugs, diagnose ...

Researchers have developed a bubble microrobot capable of being guided around the tiny complex blood vessels of the brain using ultrasound. Successfully tested in mice, the ‘microvehicle’ holds ...
