This video shows a microbot that, at just 1/4 millimeter wide, is so small that it can swim inside human arteries and help doctors carry out intricate surgeries to save lives. Developed by a research team from Monash University, this microbot has a flagellum powered by a micromotor at its tail end that allows it to swim. It gets its power from piezoelectricity and is also equipped with a camera that allows surgeons to 'see' inside a problematic artery.
