When we think of robots, we think of these huge and rigid metal machines. However, a group of scientists is challenging the way we see the robots, as they have developed what is described as the world’s first live and self-healing robot that they made using the stem cells of a frog.
Nicknamed the xenobots (named after the frog with African claws whose stem cells used), these are live robots that are less than a millimeter wide, which makes them small enough where they can enter a human’s body. They are also able to walk, swim, work together in groups and survive without food for weeks.
According to Joshua Bongard, one of the principal researchers at the University of Vermont, “These are novel living machines. They are not a traditional robot or a known animal species. It is a new class of artifacts: a living and programmable organism. “ One of the benefits of this design is that they are greener and safer for human health.
This is because, according to researchers, traditional robots tend to degrade over time and will produce harmful side effects to health and the environment. At this time, there are several potential uses for xenobots, such as cleaning radioactive waste, collecting microplastics in the oceans, administering medications inside our bodies or even scraping our plaque arteries.
