Scientists from Tufts and Vermont Universities in the United States have created a kind of “living robot“, which have the ability to reproduce. They are called Xenobots and has a pac-man-like appearance.

These xenobots release their “babies” through the “mouth”, creating copies of themselves. They arose from cells taken from the embryo of a frog (species xenopus levis, hence the name xenobo) to create small automata. Under controlled laboratory conditions, cells self-assembled into small, circular structures that could then move singly or in groups, swim in liquids, and even work together to pick up particles and stack them into each other.

The first generation of these little robots was already capable of putting particles together, while the second and current generation have developed the ability to recognize and assemble cells and put them together to form another organism just like the original.

The new xenobots are naturally prone to breeding. Left in a saline solution, the cells naturally stick together and become spheres of the epidermis, covered in a layer of tiny hair-like protrusions that rotate and allow the spheres to move across the surface.

Moreover, it is interesting to note that this form of replication does not exist in any other animal or plant in nature., but it works on these molecules. According to the paper Kinematic Self-Reproduction in Reconfigurable Organisms, it is likely that simple self-replicating molecules played a central role in the origin of life.

As you might expect, scientists hope to go beyond the frog. The research is currently focused on creating bots with mammalian cells and determining their potential compatibility with medical applications. After much human research, the goal in the future is to create biological insulin-producing robots controlled by built-in sensors to measure glucose levels.

“We could also place bots on a patient to focus on areas of damaged tissue, such as a spinal cord injury, and release regenerating compounds to aid in the recovery process. These bots are destroyed and destroyed by the immune system or fuse. in the area to become part of the forests that heal the wound.” – Professor Douglas Blakiston.
