Jinki Ittai to Premiere 'Jinki Bilateral Arm (Dual Arm Type)' at SusHi Tech TOKYO 2026

Jinki Ittai Co., Ltd. (Headquarters: Kusatsu City, Shiga Prefecture; President: Dr. Kanaoka, hereinafter 'Jinki Ittai'), a company developing humanoid heavy machinery such as the Type Zero Jinki, will exhibit at the future experience pavilion of the global innovation conference 'SusHi Tech Tokyo 2026', held from Monday, April 27 to Wednesday, April 29 (national holiday). 'SusHi Tech TOKYO' has been held since 2024, making 2026 its third iteration. This will be Jinki Ittai's first time exhibiting. The Jinki Ittai booth will be located in the West Exhibition Hall 1F Atrium. In this exhibition, we will publicly unveil for the first time the 'Dual Arm Type' of the 'Jinki Bilateral Arm,' which was previously introduced at the Advantech Co., Ltd. booth during Japan IT Week Spring 2026. Simultaneously, we are beginning to recruit test users toward the early social implementation of this technology in workplaces struggling with physical drudgery. Background of Exhibition At SusHi Tech TOKYO 2026, the focus areas are AI, Robotics, Resilience, and Entertainment. We were invited to participate under the Robotics category. Resonating with SusHi Tech TOKYO's theme of 'realizing sustainable cities with cutting-edge technology,' we decided to exhibit our robots. Exhibition Details Type Zero Jinki ver.2.0 A general-purpose humanoid heavy machine jointly researched and developed by Jinki Ittai, West Japan Railway Company (JR West), and Nippon Signal Co., Ltd., with the aim of eliminating high-altitude heavy labor in railway maintenance. It incorporates Jinki Ittai's proprietary advanced robotics technologies, such as 'force/torque control technology' and 'power amplification bilateral control technology.' The humanoid heavy machine is mounted on the boom tip of a railway construction vehicle (aerial work platform). By remotely controlling the machine from a safe cockpit, operators can perform heavy labor at high altitudes without the risk of climbing up themselves. Due to space constraints at the exhibition, the Type Zero Jinki will be shown in motion dismounted from the aerial work platform. Type Zero Jinki ver.2.0 [First Public Viewing] Jinki Bilateral Arm (Dual Arm Type) We are unveiling the dual-arm type of a collaborative robot that implements Jinki Ittai's proprietary force control technology, allowing for intuitive human operation. We will conduct a robot piloting demonstration realizing intuitive operability where 'the sense of force is transmitted' utilizing torque sensors on each axis. This robot system uses a total of four collaborative robots—two as worker machines and two as operator machines—enabling the user to freely control the robot (worker machine) as if it were an extension of their own body. This promotes the mechanization of harsh heavy-lifting tasks that are difficult to automate. For more details, please see the related release below.

Previously, enormous R&D investments were required for PoC development. However, by utilizing off-the-shelf collaborative robots, it is now possible to test the practical viability of Jinki's technology at various sites using only the fees required to provide the service. ■ Features of the Jinki Bilateral Arm Because it is operated by a human, it can flexibly adapt to complex tasks and diverse work environments. It can perform work without the prior teaching process traditionally required. There is no need for the complicated pre-adjustments and settings typical of conventional industrial robots. It boots up immediately upon connecting to power, allowing operations to start as soon as it is introduced to the site. Unlike traditional industrial robots, it does not depend on a specific installation location or base. By mounting it on various equipment or frames, it can be flexibly arranged or moved according to the site and task requirements. No special training is needed. With just tens of minutes of familiarization, operators can easily and intuitively handle heavy objects weighing tens of kilograms—which would normally require strenuous physical labor—using very little physical force. Rather than using a mirroring method that exactly replicates human motion, it converts the 'operator's force' into 'robot's force.' Therefore, the structures of the worker machine and operator machine do not need to match, allowing flexible configurations tailored to applications and physical constraints. Additionally, the displacement ratio and force ratio between the operator and worker machines can be freely adjusted.
