EXCERPTS: It’s been suggested that an advance party of robots will be needed if humans are ever to settle on other planets. Sent ahead to create conditions favourable for humankind, these robots will need to be tough, adaptable and recyclable if they’re to survive within the inhospitable cosmic climates that await them.
Collaborating with roboticists and computer scientists, my team and I have been working on just such a set of robots. Produced via 3D printer – and assembled autonomously – the robots we’re creating continually evolve in order to rapidly optimise for the conditions they find themselves in.
[...] designing robots to work in unknown or inhospitable environments – like exoplanets or deep ocean trenches – still poses a considerable challenge for scientists and engineers. Out in the cosmos, what shape and size should the ideal robot be? Should it crawl or walk? What tools will it need to manipulate its environment – and how will it survive extremes of pressure, temperature and chemical corrosion?
An impossible brainteaser for humans, nature has already solved this problem. Darwinian evolution has resulted in millions of species that are perfectly adapted to their environment. Although biological evolution takes millions of years, artificial evolution – modelling evolutionary processes inside a computer – can take place in hours, or even minutes. Computer scientists have been harnessing its power for decades, resulting in gas nozzles to satellite antennas that are ideally suited to their function, for instance.
But current artificial evolution of moving, physical objects still requires a great deal of human oversight, requiring a tight feedback loop between robot and human. If artificial evolution is to design a useful robot for exoplanetary exploration, we’ll need to remove the human from the loop. In essence, evolved robot designs must manufacture, assemble and test themselves autonomously – untethered from human oversight... (MORE - details)
