"SmartWing" is a compact 5-axis multi-joint robot characterized by its slim structure and the elimination of the need for teaching. In developing the vertical multi-joint robot, FUJI aimed to achieve a design that stands out from competitors with a smart form. The design features lines with organic curves and sharp edges, proposing that the structural components be part of the design without full coverage. The design was well-received as being perfectly suited to the product name SmartWing, and our prompt response also satisfied the client. [Case Overview] ■Challenge - To achieve a design that stands out from competitors with a smart form. ■Proposal - We proposed a design characterized by lines with organic curves and sharp edges. *For more details, please refer to the PDF materials or feel free to contact us.

We received a request from Panasonic Corporation to manufacture a model of an EV commuter for their 100th anniversary event. Due to the high difficulty and short timeline (approximately 4 months), we appointed a main person in charge for each process and formed a team to address the project. The fact that we manufactured the seats to move electrically in accordance with the customer's content also paid off, and despite the high difficulty of the project, we successfully completed a commuter that meets the customer's requirements. [Case Overview] <Challenge> - To create a performance that allows general visitors to experience unmanned driving both forward and backward, we focused on manufacturing with unprecedented safety and durability. <Result> - Despite the high difficulty of the project, we successfully completed a commuter that meets the customer's requirements. *For more details, please refer to the PDF document or feel free to contact us.

At Ark, we have supported the development of SENSOFAR for many years, handling various projects from the production of a single prototype part to small-scale production of final products. In this project, by participating from the early stages of development, we proposed and adopted a casting method for the small-scale production of several hundred units. We also made proposals for DFM (Design for Manufacturability) during the development process, assisting the company’s project to progress as smoothly and effectively as possible. [Customer Requirements] - Since SENSOFAR's products are high-value premium products, high-quality finishing of the appearance is the most important. - Due to the small production volume, we want to keep initial costs, such as molds, low. - We want to be flexible in responding to minor changes in specifications. - Additionally, we aim to meet appearance quality standards and achieve a zero-defect quality target. *For more details, please refer to the PDF document or feel free to contact us.

The "Korokoro Checker" is a robot that travels along the cables of a cable-stayed bridge, capturing and recording images of the outer circumference in 360° for exterior inspection. Arc was responsible for the renewal design of the current machine. While ensuring the inspection performance of the existing machine, we proposed solutions to challenges and achieved a balance that made development costs feasible, leading to manufacturing. We conducted wireless communication surveys and high-temperature and low-temperature evaluations, and upon design changes, we revised the instruction manual and confirmed compatibility with the app before delivery. [Proposals for Problem Solving] - We proposed improvements to enhance reliability, such as preventing damage to the brake mechanism and encoder mechanical parts. - We implemented design improvements to shorten the attachment and detachment time. - We redesigned wiring arrangements and circuit boards, taking into account reliability improvements. - To enable replacement of consumable parts, mechanical and electrical designers collaborated on enhancements. *For more details, please refer to the PDF document or feel free to contact us.*
