The title is misleading. Calling it a robot is being very generous. It's basically a propeller with magnets attached such that, if you stick it inside an externally generated magnetic field, it can fly. It's completely passive and does not have any onboard sensors.

Robot comes from the word roboto, that is work, no? If it can do autonomous work, it is a robot.

Yeah, so calling this a robot would be incorrect.

It would be more of a robot part with the rest of the robot being the magnet

Technically, maybe. Pretty limited applications, I think, but very cool.
