👾#Robots So Tiny That 100 Can Fit On Chip Smaller Than Fingertip

"Researchers at the University of Pennsylvania and University of Michigan created microscopic machines measuring just 210 to 340 micrometers wide (roughly the size of a paramecium or two human hairs laid side by side) that pack in an onboard computer, temperature sensors, memory, communication systems, and propulsion."
