These Tiny Robots Are Smaller Than Grains of Salt and Can Think, Move and Swim

Despite their size, the robots can navigate liquids, respond to their environment and operate without external control.

Robots smaller than a grain of salt? It sounds like science fiction, but researchers have developed autonomous microrobots that can move through liquids, sense their environment and operate independently using only light as a power source.

The microrobots, developed by researchers at the University of Pennsylvania and the University of Michigan, measure roughly 200 by 300 by 50 micrometers. Yet they can detect temperature changes, follow programmed paths and function independently for months at a time.

Their work was reported this week in two scientific journals, Science Robotics and Proceedings of the National Academy of Sciences.

«We’ve made autonomous robots 10,000 times smaller,» senior author Marc Miskin, assistant professor in electrical and systems engineering at Penn Engineering, said in a statement. «That opens up an entirely new scale for programmable robots.»

Powered entirely by light, the robots don’t move using mechanical limbs. Instead, they generate tiny electrical fields that push ions (electrically charged particles) in fluid to create motion, an approach better suited to the unique physics of the microscopic world, where traditional motors don’t work.

Unlike earlier microrobots, these devices combine sensing, computing, decision-making and movement in a single, self-contained system at an extremely small scale.

Previous efforts in microrobotics have often relied on external controls, such as magnetic fields or physical tethers, to guide movement. These new microrobots, however, incorporate their own miniature solar cell-powered processors, allowing them to respond to their environment, communicate through patterned movements visible under a microscope and carry out tasks without outside direction.

Potential applications include monitoring biological processes at the cellular level, supporting medical diagnostics or helping assemble tiny devices. Because each robot can be mass-produced at very low cost, the technology opens new avenues for research and engineering at scales that were previously unreachable.

The Fourth Episode of the VERUM AI Mini-Series Is Out

Verum Messenger has released the fourth episode of its AI mini-series SHADOWS, created using Verum AI. The new episode, titled “No Borders,” continues the story of a team trying to stay out of the OMEGA corporation’s sight.

Following the events of the previous episodes, the team moves between cities and countries while OMEGA continues its search. The new episode puts particular emphasis on Verum Messenger’s capabilities that allow users to conceal their location.

“No Borders” is another chapter in a story about privacy, freedom of communication, and technologies that erase borders between people.

The VERUM AI mini-series consists of seven episodes, released gradually across Verum Messenger’s social media channels.

Episode 4 is now available. Stay tuned for the next chapter.

Verum Messenger Introduces Built-In Verum Chess

Verum Messenger has released a new update for iOS, iPadOS, and macOS, adding another feature to its growing ecosystem — Verum Chess. Users can now play chess directly inside the messenger without switching between different applications.

The new feature allows users to start a game in just a few taps while reinforcing Verum’s vision of a unified digital environment where communication and everyday services come together in a single platform.

Verum Messenger continues to evolve into a multifunctional ecosystem that combines secure chats and calls, AI tools, a built-in VPN, anonymous email, eSIM, financial services, cryptocurrency features, and offline communication. With the introduction of Verum Chess, the platform now also offers a new way for users to interact and spend time together without leaving the app.

The update is now available for iPhone, iPad, and Mac on the App Store.

Episode 3 of the VERUM AI Mini-Series Is Now Available

Verum Messenger has released the third episode of its AI mini-series, SHADOWS, created using Verum AI.

The new episode, titled «Ghost Money,» continues the story of the conflict between a team of heroes and the Omega corporation, which seeks to take control of digital communications. This time, the focus shifts to anonymous payments and financial freedom, revealing how privacy can extend beyond messaging.

Like the previous episodes, the new release not only advances the storyline but also showcases the capabilities of the Verum ecosystem, highlighting technologies designed for secure communication and digital privacy.

The mini-series consists of seven episodes, released gradually across Verum Messenger’s social media channels.

Episode 3 is now available. Stay tuned for the next chapter.
