Mark Oleynik hopes to change the home kitchen by introducing a robot cook that is as good as a top chef but which can be installed in all houses. It can, in principle, be used to cook more or less anything: a pair of dexterous robotic hands suspended from the ceiling assemble the ingredients, mix them, and cook them in pots and pans as required, on a hob or in an oven. A prototype of the idea, unveiled in Hanover, has been demonstrating its culinary prowess in public, by whipping up an excellent crab bisque. The machine’s finesse comes because its hands, human-sized and with jointed fingers and thumbs, are copying the actions of a particular human chef, who has cooked the recipe specially in order to provide a template for the robot to copy. The plan is to support the automated kitchen with an online library of more than 2,000 recipes.
