Panasonic Corporation asked us to manufacture a model of an EV commuter for their 100th-anniversary event. While they had a concept to propose a new form of mobility to society, we initially felt that the customer's requirements were very challenging for us, as we did not have extensive experience in manufacturing actual commuting vehicles. We started the project with concerns about whether we could meet the vehicle design requirements considering weight restrictions and whether we could complete it by the delivery date. We were also worried about the possibility of operational issues at the event. However, with high morale among our team members, we aimed to leverage our ideas and technical expertise to deliver a service that exceeded our customer's expectations.

The hand, motor, and controller are integrated into one unit, allowing for gripping force, operating speed, and position control using a servo system with a stepper motor. This product achieves a firm and precise grip on a variety of objects.

We worked on the exterior design, engineering, and prototyping of the air purifier conceived by Hitachi, Ltd. Research and Development Group.

ARRK was responsible for the exterior cover design of the show model of Fuji Corporation's multi-joint robot SmartWing. Later, the design evolved into a production model.

We assisted in the design for the mass production of the lightweight power assist suit "J-PAS fleairy," which is designed to reduce the strain on the lower back during caregiving tasks. This suit detects movements and adjusts the assistive force, providing a strong sense of assistance. It features a belt winding system for weight reduction.

ARRK assisted with the design of FUJI Corporation's transfer support robot, Hug L1. This robot is designed to support movements between seated positions, such as transferring from a bed to a wheelchair or a wheelchair to the restroom, as well as assisting with standing in dressing rooms in caregiving settings.

ARRK collaborated with Hitachi's Research and Development Group to incorporate UV functionality into their air purifier. This innovative air purifier can effectively disinfect even hard-to-reach areas like the undersides of desks and chairs by irradiating them with UV light. Its compact size allows it to maneuver easily in tight spaces, providing thorough air purification.

ARRK provided total support, from redesigning existing products to design, prototyping, and mass production, for J-TEKT's power assist suit "J-PAS LUMBUS." This suit is designed to reduce the burden on the lower back in various work environments and features control technology developed by J-TEKT in electric power steering, along with a mechanism that can harmonize with human movement, allowing it to adapt to a wide range of tasks.

This is a self-propelled training robot designed with the aim of improving walking ability and extending healthy lifespan. It offers three modes「Arm Swing Training」「Resistance Training」「Assisted Walking」allowing users to choose the most suitable training based on their level of independence and daily physical condition. We assisted in the design, engineering, and prototyping of this product.
