Tech-Crunch:-World’s first microrobot for surgery, wide as two human hairs

In August, we looked at a micromotor powered by bacteria created by researchers in Japan. This new microrobot will also based on bacteria, and will use flagella as power to move through the human bodies.

Guided by remote control, it will swim to a site within the body to perform a series of tasks, then return to the point of entry where it can be extracted, again by syringe.”

The prototype for this microrobot (image above, video below) is as small as a grain of salt. Amazing…
