Researchers reveal new pink patch of moving skin

RResearchers looking for more complex humanoid robots have found a new way to make an artificial face move, in the form of a small pink blob with glass eyes.

The invention, led by Professor Shoji Takeuchi of the University of Tokyo, is arguably frightening at first glance. But scientists say the new technique could bring benefits such as “increased mobility, self-healing capabilities, built-in sensing capabilities and an increasingly realistic appearance” to robots. according to a press release. The newly designed face could also be useful for training plastic surgeons, cosmetic research and possibly even drug development.

To bring the robot’s face to life, the researchers made small special perforations inspired by the ligaments in the skin. The team of scientists used a special collagen gel to adhere to the fake skin tissue.

“By mimicking ligamentous structures of human skin and using V-shaped perforations specially made in solid materials, we have found a way to attach skin to complex structures. The skin’s natural flexibility and strong adhesion method mean the skin can move with the robot’s mechanical components without tearing or peeling,” said Takeuchi. Wednesday.

Takeuchi has been at the forefront of innovation in his field. His laboratory, the Biohybrid Systems Laboratory, has already worked with 3D printed laboratory-grown meat and “living” robot skin, which led him to research the subject further.

Others, like The British company Engineered Arts, are also trying to make robots more human-like, like Americawhich they describe as the “most advanced” humanoid robot in the world.

In future developments of this project, Takeychi’s team hopes to create more realistic skin by adding sweat glands, pores, blood vessels and more.

“Of course, movement is also a crucial factor, not just material, so another important challenge is creating human-like expressions by integrating sophisticated actuators, or muscles, inside the robot,” Takeuchi added. “Creating robots that can heal themselves, sense the environment more accurately, and perform tasks with human dexterity is incredibly motivating.”
