As robots gradually move from research labs into real-world tasks, a key question emerges: how do machines learn to handle complex, delicate work? At a Beijing robotics company, engineers are hand-training robotic hands, translating human experience into digital skills that can be replicated at scale. CGTN's Yang Xinmeng explores this emerging profession, speaking with the people who teach machines to cook, care and manipulate objects with precision. Their work offers a rare glimpse into the intersection of human ingenuity and artificial intelligence, as well as into the ways humans and robots may collaborate in everyday life.
