Researchers have successfully created the world's smallest fully autonomous robot, measuring a mere 200 micrometers in size. The device is small enough to be held on the tip of a human finger and can swim underwater for months using only light as its power source.
The breakthrough was achieved by a team of researchers from the University of Pennsylvania and the University of Michigan who developed a novel propulsion system that exploits the phenomenon of moving charged particles in liquid. By generating an electric field around itself, the robot creates a water current that carries it through the water without the need for arms or legs.
This technology has significant implications for various fields such as medicine, where it could be used to monitor individual cells, and engineering, where it could be employed to assemble tiny devices. The robot's ability to operate autonomously and make decisions on its own means it can work independently of external controls, reducing the need for complex infrastructure.
At the heart of this technology is a highly miniaturized computer that packs all the necessary components into a space smaller than 1 mm. This includes a processor, memory, and sensors, making it one of the smallest computers ever built.
The researchers also developed an electronic sensor that can detect minute temperature changes in its surroundings. It translates these readings into "dance moves," which are unique to each robot, allowing them to communicate with each other and perform complex tasks collaboratively.
While still a relatively new technology, this innovation holds great promise for various applications and could pave the way for even smaller robots in the future.
