Scientists have been trying to make a robot with human qualities for a long time. Although it is still impossible to make such a robot, US scientists have claimed to make the world’s first ‘living’ robot. They named it Xenobots.
This robot is made from the stem cells of the African clawed frog (Xenopus levis). Xenobots, less than one millimeter wide (decimal zero 4 inches), are also named after African frogs. Scientists claim that this robot can cause reproduction. This reproduction occurs in a way that has never been seen before in any plant or animal.
During research last year, scientists found that tiny cells could move. In addition to working together, they can recover on their own. According to a report by Business Insider, the cells contain tiny hairs called cilia. These help to move around. Researchers say the living robots are confined to the laboratory. They blend in easily with the environment and are made in accordance with scientific ethics.
Researchers at the University of Vermont, Tufts University and the Oasis Institute for Biologically Inspired Engineering at Harvard University have worked on the robot. Sam Craigman, a scientist who worked with researchers at the three universities, said: We have tried to figure out what kind of work a small robot can do. We’ve seen that it can clean the dishes.”
Michael Levine, director of the Allen Discovery Center at Tufts University and a biologist, said there are common ways to breed frogs. But when stem cells are separated from embryos and given the opportunity to reproduce in their new environment, they adopt new methods. Josh Bongard, a professor of computer science and robotics expert at the University of Vermont, says stem cells have the ability to develop into a variety of cells.
Genobots are used to separate stem cells from frog embryos to provide a suitable environment for reproduction. But no genetic change is brought. It can work on its own. So on the one hand it is a robot, on the other hand it is a creature. Since it is made up of genetically modified frog cells. This sphere-shaped robot, made using 3,000 cells, can reproduce. However, it happens subject to certain conditions.
However, researchers believe that this technology is still in its infancy. Scientists believe that in the future, artificial intelligence and various methods of molecular biology can be used. However, such technology capable of self-replication can cause concern.
