Science News: 'Burlington (USA) About two years ago, Scientists from the University of Vermont (UVM) introduced the so-called xenobots. At that time, they still had to be assembled by hand from frog cells according to the blueprints of an AI.
'The team has now taken a huge step forward by allowing the tiny robots to reproduce themselves, as explained in the research journal PNAS (DOI: 10.1073/pnas.2112672118). This represents a groundbreaking breakthrough that will allow robots to be used in humans in the future.
'They initially consisted of around 500 to 1000 skin and heart muscle cells from frogs. A computer algorithm, which was supposed to build machines for very specific tasks, had previously delivered the blueprint for the bots. This resulted in mini-robots that crawled independently on four little legs through a Petri dish. Some of the less than a millimeter small specimens were even able to transport tiny objects. The mini-robots use the reserves of the cells as fuel, which can supply energy for several days.'
