Scientists are making skin that can morph into various facial expressions for humanoid robots, inspired by skin ligaments. The method involves pouring a gel with skin cells into drilled holes in the robot's skeleton, solidifying it into 'ligaments' that attach the artificial skin to the robotic 'face.'
The attached skin retains flexibility and can be shaped into various expressions, such as smiling. By enveloping a 3D human-like face mould and creating a flat skin layer, researchers are progressing towards more human-like robot faces.
Despite advancements, there's still a long journey ahead for robots to resemble humans convincingly. The study highlights the complexity in achieving natural human expressions in robots, emphasizing the ongoing challenges in this field.
