Scientists at the University of Tokyo have achieved a major breakthrough in robotics by growing living skin in a lab and attaching it to a robotic face to create rudimentary facial expressions. This development could lead to robots with new capabilities such as self-healing and an advanced sense of touch, bringing them closer to a more human-like appearance. The lead researcher, professor Shoji Takeuchi, is focused on creating robots that combine the strengths of both machines and biology. The ultimate goal is to replicate human appearance and movements, integrating features like sweat glands, blood vessels, and nerves. This research opens up a world of possibilities for the future of robotics, but also raises ethical questions about the implications of creating robots that closely resemble humans.
