    > Both robots are magnetic and guided wirelessly by an external electromagnetic coil system

    That’s so cool. It reminds me of being a kid and playing with magnets beneath a sheet of cardboard, using them to invisibly move metal objects on the surface. Is that sort of the principle here?

    Sounds like great weapon to assassinate someone.

    Jokes apart, can anyone well versed actually tell of this is just a paper for publishing sake or is there any truth to this story ?

      > The researchers successfully tested the robots on phantom heart models that closely mimic a human heart, and on real porcine heart tissue. The robots traveled smoothly and autonomously, even against simulated blood flow.

      “In mice” - actually not even.

        I think the researchers and I (and probably most other people) have a different definition of “autonomously”.

      Not really, as your victim would also need to be in an MRI-like machine for fifteen minutes to an hour.

      I do hope this is serious research as well. It’s hard to tell from the outside.

    if they manage to drive small robots, they could probably also drive magnetotactic bacteria...!

    I for one welcome our magnetic millirobot overlords into my beating heart.
