Croak, Croak! Here Comes Living Robots Made of Frog Cells

Scientists have now created tiny robots from cells scraped from frog embryos which has the potential for several interesting applications in medicine. 
These tiny 'xenobots' can be used to deliver medicine to a specific place inside a patients’ body and heal themselves after being cut. These living organisms were designed on a super computer at UVM and then assembled and tested by biologists at Tufts University. It can have other applications such as searching for nasty compounds or radioactive contamination, gathering microplastic in the ocean, travelling to scrape out plaque. This is the first time a biological machine is being designed completely from ground up, according to scientists at Center for Regenerative and Developmental Biology at Tufts University. The stem cells for the biological machine were taken from the embryos of African frogs, the species Xenopus laevis (Hence the name 'Xenobots')

Compared to similar technologies made using steel, concrete or plastic, the 'xenobots' are fully degradable and capable of regenerating when required.The 'xenobots' were cut several times only to regenerate itself which is not possible with any other objects.
