| DESIGN NAME: Jizai Arms PRIMARY FUNCTION: Supernumerary Robotic Limb System INSPIRATION: In “One Arm”, Nobel Prize-winning author Yasunari Kawabata wrote a weird scene that a girl gives her arm to a man and a man stay a night with it. He vividly described a man’s experience at the night with his wide-ranging emotional changing. After a half a century, emerging human-machine integration technologies have begun to allow us to physically experience Kawabata’s world. “JIZAI ARMS” are designed to explore possible interactions between digital cyborgs in a cyborg society. UNIQUE PROPERTIES / PROJECT DESCRIPTION: JIZAI ARMS is a supernumerary robotic limb system. It was designed to enable social interaction between multiple JIZAI ARMS wearers such as an exchange of arms.JIZAI ARMS is a supernumerary robotic limb system consisting of a wearable base unit with detachable robotic arms. The system has been designed to enable social interaction between multiple wearers, such as exchanging arms, and to explore possible interactions between digital cyborgs in a cyborg society. OPERATION / FLOW / INTERACTION: JIZAI ARMS is a system contains wearable base unit and detachable robotic arms. Robotic arms which connected to base unit are controlled by computer. In current prototype, robotic arms are controlled using a 1/2 scale model as a controller, operator can control arms with moving a model like puppet. Using this controller, operator controll robotic arms intuitively since a posture which operators made with model is directly applied to actual robotic arms. PROJECT DURATION AND LOCATION: The project started in Nov 2021 in part of JST INAMI JIZAI BODY PROJECT and completed production in September 2022. JIZAI ARMS has firstly used and shown in dance performances in JIZAI Collection held at Tokyo in Novenber 2022. |
PRODUCTION / REALIZATION TECHNOLOGY: This system contains a wearable base unit which has six terminal to attach arms and board to communication, and robotic arms with 5 DOF. Exterior parts are designed with organic and complex shape to cover only necessory part and make it lighter, 3D printing enabled these complex shape. We designers worked from considering basic engineering specification like motor layout and geometry of arms, to finalize exterior design. This process made sophisticated design. SPECIFICATIONS / TECHNICAL PROPERTIES: Width 900mm x Depth 400mm x Height 1000mm *A system contains attachable/detachabl TAGS: Cyborg, Digital Cyborg, Social Digital Cyborg, Supernumerary Robotic Limb System, Robotic Limbs, Wearable Robotic Limbs, Human-Machine Integration, Human-Computer Integration, Robotics, Human-Robot Integration RESEARCH ABSTRACT: JIZAI ARMS is a prototype to explore possible social interactions between digital cyborgs in a cyborg society, such as gifting body parts or exchanging arms. In existing research in human augmentation, interesting changes of embodiment happened through using wearable robotics has reported. We focused not only individual wearer but also embodied experience happen between multiple digital cyborgs, and made JIZAI ARMS as a prototype to make such experiences real. CHALLENGE: Enabling quick and free attach/detach of arms is a core concept of JIZAI ARMS and system design for this feature was one of a hard point. Production team invented connection system enables easy attach/detach and connect both electrically and physically, but stiff enough as a base of robotic arms. From styling perspective, achieving a beautiful fusion of human body and machine was a challenging point. We designed this robotic system rationally but tried designing it visually fit to human body.

NAME: The University of Tokyo PROFILE: For the Inami JIZAI body project, we aim to establish a technological foundation for building a "freeing body" that can adapt to the super smart society. Technology development that is positioned as "freeing" is thought to support human beings acting with robots and AIs "unity with human beings" while maintaining sense of self-awareness, and widening the possibility of human actions significantly. In order to realize the JIZAI body concept, we use assistive robotics, wearable computing, brain information decoding, machine learning, virtual reality, etc. We will establish the design guidelines and elucidation of the fundamental knowledge on "body editing”. Furthermore, we will examine the the mind and society changes on the JIZAI body in real and virtual societies. |
