As depicted above, robots will be “born” through the use of 3D manufacturing. We use a new kind of hybrid hardware-software evolutionary architecture for design. That means that every physical robot has a digital clone. Physical robots are performance-tested in real-world environments, while their digital clones enter a software programme, where they undergo rapid simulated evolution. This hybrid system introduces a novel type of evolution: new generations can be produced from a union of the most successful traits from a virtual “mother” and a physical “father”.

As well as being rendered in our simulator, “child” robots produced via our hybrid evolution are also 3D-printed and introduced into a real-world, creche-like environment. The most successful individuals within this physical training centre make their “genetic code” available for reproduction and for the improvement of future generations, while less “fit” robots can simply be hoisted away and recycled into new ones as part of an ongoing evolutionary cycle.
