About Jizai Arms Sistem prekobrojnih robotskih udova

Jizai Arms je sistem prekobrojnih robotskih udova koji se nosi na tijelu. Sistem se sastoji od nosive bazne jedinice sa šest terminala i odvojivih robotskih ruku, od kojih svaka ima pet stepeni slobode. Ruke se mogu brzo pričvrstiti i skinuti, tako da korisnici mogu međusobno razmjenjivati ruke. Vanjski dijelovi proizvedeni su trodimenzionalnim štampanjem, što omogućava složene oblike i smanjuje težinu. Rukama se upravlja pomoću modela u pola veličine koji se pomjera rukom, a položaj modela se direktno prenosi na robotske ruke.

Unique Properties: 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.
Dimensions & Packaging: Width 900mm x Depth 400mm x Height 1000mm

*A system contains attachable/detachable robotic limb and wearable base unit, dimensions changes up to layout and posture of arms.

Production 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.
Design 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.
Research: 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.
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.
Project Duration: 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.
Operation Flow: 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.
