Scientists have created a robot that can replicate itself in minutes. The team behind the machine says the experiment shows that self- reproduction is not unique to living organisms. Developed by researchers at Cornell University in Ithaca, New York, the machine was constructed from cube-shaped robotic unitsthat functioned independently. A four-module robot could assemble an exact replica of itself in just two and a half minutes. The researchers add that the ability could be harnessed to drive major advances in nanotechnology, and may even lead to space colonization by robots. More
