In a major breakthrough, scientists used human cells and created tiny living robots which are able to move around in a lab dish and are likely to heal damaged tissue and wounds someday, as per a new study. 
 
A team, comprising students from Harvard University’s Wyss Institute and Tufts University, have called these creations anthrobots. The research was the follow-up of similar work done by the same scientists. These scientists had earlier made the first living robots, called xenobots, using stem cells sourced from African clawed frog embryos. 
 
“Some people thought that the features of the xenobots relied a lot on the fact that they are embryonic and amphibian,” study author Michael Levin, Vannevar Bush professor of biology at Tufts’ School of Arts &amp; Sciences said, as reported by CNN. 
 
“I don’t think this has anything to do with being an embryo. This has nothing to do with being a frog. I think this is a much more general property of living things. We don’t realize all the competencies that our own body cells have,” he added.

“While alive, the anthrobots were not full-fledged organisms because they didn’t have a full life cycle. It reminds us that these harsh binary categories that we’ve operated with: Is that a robot, is that an animal, is that a machine? These kinds of things don’t serve us very well. We need to get beyond that,” Levin said. 
 
The research was published in the journal Advanced Science on Thursday (Nov 30).

<h2>How were these living robots made?</h2>

Adult human cells, which were taken from the windpipe or trachea of anonymous donors who were from different sexes and ages, were used by the scientists. 
 
This type of cell was selected by the researchers because they are comparatively easy to access due to the work done on COVID-19 and lung disease and, because of a feature which as per scientists will make cells capable of motion, as per study coauthor Gizem Gumuskaya, who is a doctoral student at Tufts.

“Nothing happened on day one, day two, day four or five, but as biology usually does, around day seven, there was a rapid transition. It was like a blossoming flower. By day seven, the cilia had flipped and were on the outside,” Gumuskaya said. 
 
“In our method, each anthrobot grows from a single cell,” she said. 
 
“It’s this self-assembly that makes them unique. Biological robots have been made by other scientists, but they were constructed by hand by making a mould and seeding cells to live on top of it,” said Levin.

Scientists create tiny living robots from human cells which may heal wounds

U.S. scientists who made the world's first computer-designed living robots said that the 'Pac Man' shaped organisms are capable of self-replication.

Xenobots represent new form of biological reproduction

Scientists in the US have developed the world's first living robots that can walk, swim using frogs' stem cells.&nbsp;

The living machines are named&nbsp;as Xenobots, after the African clawed frog (Xenopus laevis) from which they have taken their stem cells, reported CNN. The machines are less than a milimetre&nbsp;in size and look like a moving pink flesh.&nbsp;

Xenobots can swim, walk, survive for days without food and work together in groups.&nbsp;

The scientists scraped living stem cells from frog embryos. They left them to incubate. After this, the cells were cut and reshaped into specific "body forms", said a news release from the University of Vermont.

The cells later started to work on their own. The skin cells combined to form a structure and pulsing heart muscle cells enabled the robot to move on its own.&nbsp;

The robots also have self-healing capabilities.&nbsp;

Joshua Bongard, one of the main researchers of the project, described Xenobots as "novel machines". He also said the new robots are "artfact", "a living, programmable organism".&nbsp;

The study also claimed that robots are more environmental-friendly and safer for human health.&nbsp;

The robots can perform tasks such as cleaning radioactive waste, carrying medicine inside human bodies and collecting microplastics from the oceans, among others. They can be also placed in the arteries to scrape out plaque. &nbsp;&nbsp;
