World’s smallest autonomous robots developed by scientists
Scientists have created the world's smallest robots that can move and think on their own.
These tiny robots are so small that you can barely see them with your eyes.
They can swim, sense their surroundings, and even work together like a school of fish.
The robots were made by combining two big ideas: one for making them move, and another for giving them a tiny brain.
Each robot costs about one penny, and they can work for months without stopping.
This is a big step forward in making very small robots that can do useful things.
Researchers at the University of Pennsylvania and the University of Michigan have developed the world’s smallest fully programmable, autonomous robots.
Each robot measures around 0.2 by 0.3 by 0.05 mm, making them barely visible to the naked eye.
The robots can sense their surroundings, move in complex patterns, and operate independently for months.
The propulsion system was developed at the University of Pennsylvania, while the ultra-low-power 'brain' was created at the University of Michigan.
The robots can swim through liquid environments, respond to temperature changes, and coordinate their movements in groups.
