Technology helps robots look like real people

In research published in the magazine Robotics and Mechatronics, Researcher Hisashi Ishihara and his colleagues developed a vivid facial expression technology that moved “wave movement”, indicating gestures such as breathing, blinking and yawning in the form of a single wave. These waves spread to related facial areas and cover each other to create real -time facial movements. The new method helps eliminate complicated and diverse action data preparation requirements, while avoiding changing movements easily detected. In addition, through the introduction of “wave deformation”, adjust the single wave based on the intrinsic state of the robot, changes as mood can be immediately reflected.

Previously, even if the robot looked special like the human being in the photo, observing it moved directly could cause discomfort. The robot can smile, frown and show many familiar facial expressions, but these expressions often lack emotional basis. This lack of links creates unrealistic emotions, leading to discomfort.

So far, human -shaped robots with a flexible face characteristic based on “patchwork method” to express emotions for a long time. This approach includes many action situations and conversion between them as needed, ensuring maximum reduction in facial movement. However, that method poses many practical challenges, such as preparing complex action situations, minimizing less natural motion easily

According. work with people. This will enrich the emotional communication between people and robots. The development of the system reflects the internal emotional details that can create a “heart” robot.

Through the initiative to adjust and express emotions, new technology will significantly enhance the value of the robot, helping them exchange information with people in a natural and more natural way.
