This Insect-Sized Drone Can Fly Without any Moving Parts. How? Physics.

Researchers from UC Berkeley have built one of the smallest flying robots ever made. Not only does the insect-scale robot boast no moving parts whatsoever, but its atmospheric ion thrusters allow it to move completely silently. Could it be coming soon to a sky near you?

Alissa Goldberg’s insight:
This is incredible technology for surveying animals that are sensitive to noise, but it will be interesting to see how else this technology is used.
