Androids and Robots

Yui

An android avatar that reflects the operator’s gaze, facial expressions, and full-body movements in real time. The name Yui comes from the Japanese term for “connecting” and expresses the idea of connecting everyone around the world, opening up new doors for communication. Yui’s clothing, made from Kaga-Yuzen paste-resist-dyed silk, as well as Yui’s head and sash, decorated with Wajima-nuri lacquerware, are an expression of support and respect for the Noto region. By dressing Yui in a kimono and styling Yui’s hair in a traditional bun, the design expresses the spirit of omotenashi (hospitality) and tradition.

Role within the Pavilion
Stationed at the pavilion’s exit, Yui serves to visualize the connection point between the future and the present, conveying that a society coexisting with robots and androids is already in motion, and to offer a final “thank you” to visitors.

Specifications
  • Developed based on the mobile Cybernetic Avatar (CA) Teleco, developed as part of the Moonshot Research and Development Program* Goal 1 project: Realization of an Avatar-Symbiotic Society where Everyone Can Perform Active Roles without Constraint.
  • 60 actuation points (excluding locomotion wheels)
    -Facial skin: 22 actuation points driven by 15 motors
    -Eyeballs: 3 degrees of freedom (independent left/right movement; synchronized up/down movement)
    -Below the neck: 35 degrees of freedom
  • Electric motors
  • Skin material: Silicone
  • Head: 3D printed part finished with a coat of lacquer A three-dimensional structure that resembles hair is achieved using a parametric design based on triangles. The same pattern is applied to the sash.

 

* The Moonshot Research and Development Program

This government-led program sets forth ambitious “moonshot” goals aimed at solving major societal challenges, such as super-aging populations and climate change, and supports bold R&D efforts. Goal 1 of the program is overseen by the Japan Science and Technology Agency (JST). ISHIGURO Hiroshi serves as one of the project managers for Goal 1 and leads the project titled “Realization of an Avatar-Symbiotic Society where Everyone Can Perform Active Roles without Constraint.” This project promotes R&D to expand human physical, cognitive, and sensory capabilities through a Cybernetic Avatar (CA) platform, leveraging diverse forms of avatars including robots and CG, to realize daily life supported by CAs.

Functional Features
(1) Large number of actuation points

Excluding the locomotion wheels, 60 points across the body are capable of motion. The head, including the neck, has 28 actuation points, enabling expressive facial gestures like smiling.

(2) Extremely quiet motor operation

By minimizing mechanical noise during movement, Yui achieves a more humanlike, natural presence.

(3) Remote operation via the internet

With wide-angle cameras embedded in the eyes and microphones in the ears, operators can control Yui from remote locations as if present on site, seeing and hearing from Yui’s perspective.

(4) Auto mode that replicates human movement

In auto mode, expressions and gestures are generated based on recordings of actual human movement, enabling more natural behavior.

(5) Genderless design incorporating traditional craftsmanship

Kaga-Yuzen paste-resist-dyed silk is used for Yui’s garments, and Wajima-nuri lacquering is used for Yui’s head and sash. Yui’s outfit combines a somewhat feminine kimono with traditionally male hakama pants, resulting in a genderless appearance.
