What do you think of when it comes to AI? Robot, computer chip, voice assistant or driverless? Recently, scientists from the University of Vermont and tufts have taken AI technology to a whole new level. < / P > < p > let’s meet xenobots, the first living robot that can repair itself with skin and heart cells from frog embryonic stem cells. It differs from most robots in that it is not made of plastic or metal, but is made entirely of organic cellular materials. < / P > < p > because the cells used are from the early embryos of Xenopus laevis, they are named “xenobots” after Xenopus laevis. Xenobots are about 0.04 inches wide, less than a millimeter small enough to walk through the human body, work, swim, walk, and even survive for weeks without food. < / P > < p > researchers said: “over time, traditional robots will degenerate, which may have harmful ecological and health side effects.” Compared with traditional robots, xenobots are more environment-friendly and safer to human health, which is an effective way to solve the problem of robot degradation. < / P > < p > Joshua Bongard, one of the leading researchers at the University of Vermont, said: “these novel living robots are neither traditional robots nor known animal species. They are a new kind of artifact: a living programmable creature!” < / P > < p > as mentioned earlier, xenobots are composed of skin cells and heart cells in frog stem cells. Stem cells are non-specific cells that can differentiate into different types of cells. But this brings us more questions – are they made by hand? Are super precise robots used? Are they 3D printed? The answer to these questions is yes. The manufacturing method of xenobots uses both precise technology and human intervention. First, the researchers extracted live stem cells from frog embryos and then allowed them to hatch. Next, a supercomputer will design a specific “body shape” for the cells and do it many times to determine which model works best. According to UVM, these models are “forms never seen in nature.”. The researchers then used these computer-generated designs to simulate real cells. Technicians go through a very intense process of modeling each cell one by one and connecting it to other cells. < / P > < p > xenobots are shaped into various forms, each of which is used for different purposes. For example, xenobots with a snow sweeper like attachment can remove loose particles like those in a Petri dish at night and pile them up; some have leg like appendages that can be dragged around the floor of the Petri dish; and some can swim by spinning hairs. < / P > < p > these xenobots are pre loaded with lipids and proteins, enabling them to survive for about a week, but they cannot reproduce or evolve. In a nutritious environment, its life span can be extended to several weeks. The organic structure and appearance of xenobots are not the high-tech robots we can see on TV. According to the report, a robot is “any kind of automatic machine that replaces human efforts, although it may not look like human beings or perform functions like human beings.” < / P > < p > however, there is no Bluetooth chip inside xenobots, and there is no remote control device for scientists to command them. How do scientists make robots entirely from organic materials? < / P > < p > this is also the question researchers want to answer: can they get real cells and manipulate them to operate in the way researchers want them to operate OK, like a robot made of plastic or metal? < / P > < p > we know the structure of xenobots is composed of frog heart and skin cells. What does that mean? Heart cells contract naturally, but skin cells don’t. So the idea is that they can put skin cells and heart cells in a specific structure, model or location and use them as a functional “living robot” that can move around and repair itself. < / P > < p > xenobots can move in different ways depending on the location of non contractile skin cells and contractile heart cells. In the picture, we can see a computer-generated model with skin cells on the top and heart cells on the bottom, which enables xenobots to swing with leg like attachments. According to the computer-generated structure, xenobots can also perform certain actions, such as hobbling, swimming, and even spinning. < / P > < p > in theory, xenobots means a big step forward in artificial intelligence, but in reality, what can it do for the world? It’s only as wide as a pencil lead. How can it change the lives of so many people in the world? < / P > < p > xenobots are very small. If we want, we can let xenobots carry drugs into the human body, or even scrape plaques out of arteries; they can also self replicate to correct genetic defects or replace DNA molecules; they can act as micro surgeons to repair damaged arteries Damaged cells or completely replaced intracellular structures. < / P > < p > over the years, the content of plastics in the ocean has increased significantly, and there is even a garbage belt as big as Texas in the Pacific Ocean. Solving this problem will be extremely beneficial to aquatic species and the quality of our water supply. If xenobots were sent to the ocean to collect plastic particles, it would benefit everyone. < p > < p > the growth of plant and animal wastes will cause many genetic problems. Nuclear energy is very important, we must find more effective solutions to clean up nuclear waste. Xenobots have the potential to solve the dangerous problem of nuclear waste. If they are put in areas prone to nuclear waste, they will play a huge role. < / P > < p > xenobots can also help researchers learn more about cell biology, and open the door for the future development of human health and longevity. < / P > < p > the researchers wrote on their website: “if we can create 3D biological forms on demand, we can repair birth defects, reprogram tumors into normal tissues, regenerate after traumatic injury or degenerative diseases, and overcome aging.” < / P > < p > the amazing xenobots may sound like the plot of a science fiction movie, and people will inevitably have concerns. But researchers say there’s no need to worry too much. Although supercomputers, a powerful artificial intelligence, play an important role in making these robots, they are unlikely to produce malicious effects. < / P > < p > xenobots have great potential in the future. Scientists have been challenging the boundaries between biology and numbers. The progress that mankind can make in the future will definitely change the fields of medicine, biology and artificial intelligence forever, and will also make the world cleaner and save more lives. gather and watch!
