A robot made from fully living cells

Artificial Intelligence Development and CreationThe latest robotic systems easily penetrate our lives. Developing medicine will soon be difficult to do without robotic technology, as some operations are already carried out using robots, and the use of robotic prostheses helps people with disabilities live a full life. In addition to medical use, robots have long been used in space exploration, in production and at home, as well as for many types of entertainment. But if earlier robots were a “cocktail” of microchips and cans, then today scientists have managed to create the first robots from living cells.

Using special algorithms, scientists were able to create a robot from living cells.

Live robots

According to an article published on the, scientists have been able to create the world's first robots that are completely composed of living cells. The so-called xenobots are tiny balls that contain from 500 to 1000 cells, while they can even move around the Petri dish, organize themselves and transport the smallest payloads. According to scientists, xenobots are not like any living organism or organ that we are familiar with today.

Experts note that the latest living machinesThere are many opportunities for their implementation and purpose, ranging from targeted drug delivery to environmental restoration. Xenobots cannot yet be accurately classified, since they cannot be fully attributed either to traditional robots or to known species of living organisms. Scientists believe that a new classification is needed, in which there will be a special class called “living, programmable organism”.

When creating a “live” robot, hundreds of frog heart and skin cells were used.

When implementing an unusual experiment, scientists used a supercomputer and a special algorithm with which they could collect several hundred combinations of heart cells and frog skin.

Based on the best combinationscells, scientists collected a “living robot” like a constructor. With the help of skin cells, which were used as connective tissue and frog heart cells, which performed their main ability, muscle contraction, during the experiment, xenobots could move around. Living robots could move in the aquatic environment for a week without the need for additional nutrients, in addition to those that were already in the cells in the form of lipids and proteins.

Living robots have many advantages and opportunities than their predecessors

Xenobots are fully biodegradable. When nutrients run out in xenobots, they turn into a cluster of dead cells, which in turn gives advantages over metal and plastic robots.

Despite the fact that the xenobots have a colossalpotential, scientists are wary of continuing to study their interaction with the nervous system, since there is a risk of xenobots becoming bioweapons. At the same time, experts note that xenobots are capable of large-scale use in various fields: to work with radioactive contaminants and other chemical compounds dangerous to humans, when used to collect microplastics in the oceans, as well as to travel through human arteries, which will help in the treatment of certain diseases.
