🔥 Technology is getting pretty insane

Researchers at the University of Pennsylvania and University of Michigan have created the world’s smallest fully programmable, autonomous robots.

"Microscopic swimming machines can independently sense and respond to their surroundings, operate for months and cost just a penny each."

"Barely visible to the naked eye, each robot measures about 200 by 300 by 50 micrometers, smaller than a grain of salt. Operating at the scale of many biological microorganisms, the robots could advance medicine by monitoring the health of individual cells and manufacturing
