This has gotta be the 10th "We have invented Nano-Bots!!! (That are really just shapes controlled by a big magnet outside the body) That I have seen in the past decade or 2)

It's the equivalent of moving around a mini sailboat in a pool using a leaf blower. Just because you found ways to make it move in incredible ways, doesn't make it a robot.

None of them are ever robots and none of them are ever Nano-Bots. Yes, they are useful advances in medicine, but every article, (and seemingly the researchers too,) love to sensationalize them to high heaven.

If Trump was a worm and a few tens of micrometers long, then yes

They're made by a laser 3D printer and they only move in an externally applied electric field. I don't think we have to worry about anything like that anytime soon :)
