Video.. "Robot" Smiles Like a Human!

In a groundbreaking achievement in the world of technology, Japanese scientists have succeeded in making a robot smile "naturally" by using human cells. Researchers from the University of Tokyo showcased their findings in a study published in the journal "Cell Reports Physical Science," and released a video in which a group of robots displayed a natural yet frightening smile. The scientists developed the "natural smile" by injecting gelatin into human tissues that were inserted into holes in the robot, a method inspired by the actual ligaments in human skin. Experts hope that this technique will provide a better understanding of wrinkle formation and the physiology of facial expressions, and contribute to the development of materials for organ transplantation and cosmetic products.
