Robotics Expert Told Filmmaker Kore-eda: Human Clones Will Come First

A robotics expert told Palme d'Or winner Hirokazu Kore-eda, while advising his sci-fi film "Sheep in the Box," that human clones would arrive before convincing humanoid robots. The reason: heat. Bipedal robots generate excess heat their bodies can't shed — a thermal management problem that puts the film's child-sized robotic surrogate premise beyond today's engineering roadmap.
