Researchers Consider The Advantages of 'Swarm Robotics' (msn.com) 29

The Wall Street Journal looks at swarm robotics, where no single robot is in charge, robots interact only with nearby robots — and the swarm accomplishes complex tasks through simple interactions.

"Researchers say this approach could excel where traditional robots fail, like situations where central control is impractical or impossible due to distance, scale or communication barriers." For instance, a swarm of drones might one day monitor vast areas to detect early-stage wildfires that current monitoring systems sometimes miss... A human operator might set parameters like where to search, but the drones would independently share information like which areas have been searched, adjust search patterns based on wind and other weather data from other drones in the swarm, and converge for more complete coverage of a particular area when one detects smoke. In another potential application, a swarm of robots could make deliveries across wide areas more efficient by alerting each other to changing traffic conditions or redistributing packages among themselves if one breaks down. Robot swarms could also manage agricultural operations in places without reliable internet service. And disaster-response teams see potential for swarms in hurricane and tsunami zones where communication infrastructure has been destroyed.

At the microscopic scale, researchers are developing tiny robots that could work together to navigate the human body to deliver medication or clear blockages without surgery... In recent demonstrations, teams of tiny magnetic robots — each about the size of a grain of sand — cleared blockages in artificial blood vessels by forming chains to push through the obstructions. The robots navigate individually through blood vessels to reach a clog, guided by doctors or technicians using magnetic fields to steer them, says researcher J.J. Wie, a professor of organic and nano engineering at Hanyang University in South Korea. When they reach an obstruction, the robots coordinate with each other to team up and break through. Wie's group is developing versions of these robots that biodegrade after use, eliminating the need for surgical removal, and coatings that make the robots compatible with human tissue. And while robots the size of sand grains work for some applications, Wie says that they will need to be shrunk to nano scale to cross biological barriers, such as cell membranes, or bind to specific molecular targets, like surface proteins or receptors on cancer cells.

Some researchers are even exploring emergent intelligence — "when simple machines, following only a few local cues, begin to organize and act as if they share a mind...beyond human-designed coordination."

  • just keep them away from the stargate and any military system

    • My first thought was the Borg from Star Trek. However, yes, I think a swarm of small helicopters could overtake any aircraft carrier, any warship, could take down any airplane. In my thought experiments, this is an incredibly powerful weapon.
      • Earlier than that. Don't forget about the swam ships seen on Enterprise.

        They're run by...the Suluban (sp?) I think.

        • Also on Strange New Worlds, the Gorn Hemogeny run those.

        • I thought the Enterprise .. the Suluban .. was kind of lame. I had mixed feelings. Not that I matter. I am now glad that they are part of the Star Trek Universe. They showed that a woman Vulcan can be hot as hell!!
    • Too late surely. I heard a Ukrainian robot nerd on a CBC interview just after the war broke out. It was a fairly terrifying vision of how swarms of drones can target weaknesses on enemy hardware and take out supposedly superior weapons. The Russians are getting great mileage out of cheaper drone style munitions as are the Ukrainians.
      • Against the real military because a real military will very quickly have air superiority and can fly planes that drop bombs at altitudes that most drones can't reach. If you have the kind of drones that can reach those planes then you also have enough of a military to maintain some semblance of air superiority.

        Russia doesn't have a modern military. They probably should but they don't because of rampant corruption. That's why I ride tag group of drones can drag them to their knees.

        • That's hilarious, they don't have a *real* military?

          I don't know what you consider a real military, but assuming that you think the US has a real military by your standards, I'll point to Afghanistan, where a rag tag of AK-47 wielding militiamen just kicked their ass out of the country. Same in Iraq, which caused a 10-year trauma in the US population as evidenced by the amount of movies produced about the conflict aiming to heal the psychological wound and the political impact. Same in Vietnam, where the t

          • I don't know what you consider a real military

            One example is Israel and we have seen very clearly in Gaza that Hamas prepared for and in fact started with drone warfare. On October 7th drones were used for the initial attacks on the wall. From that point on, there has been almost no mention of and no serious effect from Hamas drones and even Hezbollah drones have been largely ineffective. Iran's drone attack also largely failed and they had to revert to traditional ballistic missile attacks to cause any damage to Israel.

            Needless to say, Chinese or Amer

    Swarms of robots are going to make the world a better place, how?

      Would be good in search and rescue applications.

      Lost at sea, lost in the desert, etc.

      That would be a guess at this point, but they could be good at construction, at search .... ask what ants and termites are good at, and they could be good at that list and more.

      There was a story on Slashdot the other day about building windmills with blades so large that they can't be transported on the highways. The solution being explored was to build the largest airplane ever to carry them, then create a temporary landing strip for it. A better solution might be a drone swarm could attach to the blade and cooperatively carry the thing to the site. Package too large for a single Amazon drone to deliver? Add more drones.

  • The best thing for the environment, in the long run, is to let the wildfires burn themselves out. Sure, try to stop the fires from burning down homes, but grassland and forests should be fair game.

    Kilobot [wikipedia.org] 2012

    The Kilobot is a 3.3 cm tall low-cost swarm robot developed by Radhika Nagpal and Michael Rubenstein at Harvard University. They can act in groups (over a thousand), to execute commands programmed by users that could not be executed by individual robots. A problem with research on robot collectives is that the cost of individual units is high. The Kilobot's total cost of parts is under $15. In addition to low cost, it has applications such as collective transport, human-swarm interaction, and shape self-assembly.

    The power source is a rechargeable lithium-ion battery that can power the robot for up to 3–12 hours depending upon how active the robot is. They are equipped with a three color (red, green, and blue) LED which displays information to the user. While wheels are effective at movement, they are expensive, which substantially increases the cost of each unit. One way the cost was lowered was using two vibrators for movement. When either is activated, the Kilobot turns at about 45 per second. When both are activated, the robot moves forward at about 1 cm/s. The robot stands on 3 rigid legs, which elevates the robot 2 cm above the surface. The individual robots are equipped with an infrared transmitter and receiver so that they can communicate with each other. The transmitter of a robot sends light toward the surface which reflects up to the receiver of another nearby robot, which then executes a command based on the program. Some drawbacks of these methods of communication and movement are: the area on which the Kilobot works is limited to flat surfaces and the inability to move precisely over long distances or over an extended period of time.

    Obviously only useful in a lab setting, but still a physically realized example of swarm robotics over 12 years ago.

    There is a reason they are so successful.

  • Reminded me of that Asimov story about such robots and the problems.

  • Elon Musk is building a robot army.
    Given that he has already turned Twitter into fascist X and his Grok AI is programmed to spout Nazi fascist ideals, I can't wait for his robot army to swarm my town.
