Fantastic Voyage, but with robots
This robotic submarine, designed by scientists in Israel, has a diameter of 1mm. Using magnetic induction as a power source, it can crawl through blood veins. At the moment, that’s about all it can do — it’s still in the design phases. And it seems that the design doesn’t allow for a great deal of control, as of yet. But it’s a promising development. And for some reason the linked article concludes with an oddly in-depth synopsis of
Fantastic Voyage.
