Tiny robots building their own tools

SRI International has updated their tiny dime sized robots that can how build their own tools. The SRI unveiled their tiny robots last year, but since then they have updated and improved their robots. There is hope that the tiny robots could be improved by making the robots move through magnetic levitation. The applications for these robots will only grow as the technology improves. One day it could even be possible to have tiny robots inside a larger one repairing and carrying out small tasks. Complete building could be constructed by a swarm of thousands of them and could vastly expand the reach of human potential. Maybe even one day, we could have nano sized robots inside us fighting off viruses along side our immune system.
