Recently, Ruisong Technology, through its subsidiary Guangzhou Ruisong Robotics Technology Co., Ltd., has officially launched the production of its innovative high-precision high-speed robot (PLR robot). This marks a significant milestone for Ruisong Technology in overcoming core technologies in the high-end robotics sector, providing essential equipment for strategic fields such as semiconductors and ultra-precision manufacturing.
The production ceremony was witnessed by technical experts from Panasonic, including Mr. Mitsumura and Mr. Takano from the Circuit Formation Division. Ruisong Technology’s breakthroughs in high-end robotics have not been achieved in isolation but through a solid path of “introduction, digestion, absorption, and re-innovation.” By successfully understanding and transforming the core technologies of the PLR parallel robot, the company has mastered critical technologies such as high-precision motion control algorithms and modular design. This has allowed Ruisong Technology to establish a fully autonomous R&D system and production capacity, achieving comprehensive control over the entire technology chain from core algorithms to embedded controllers and precision machinery.
Achieving a “0-1 breakthrough” and gaining international market recognition is a strong testament to the product’s value. In May 2025, the first PLR robot was delivered to a leading global display panel company for stringent on-site testing. With its exceptional stability and precision, the robot successfully passed the client’s rigorous process validation. Currently, it has gained recognition from several top-tier companies in the 3C industry, securing initial cooperation orders, demonstrating its capability to meet the demands of high-end precision manufacturing.
Notably, in the field of optical communication, which requires extreme precision, Ruisong Technology’s high-precision optical fiber assembly solution has successfully passed process validation from leading international companies. This innovative application of the high-precision high-speed robot has revolutionized the optical fiber manufacturing industry, which has long relied on manual assembly.
The PLR robot features a multi-link parallel mechanical structure and real-time embedded coordination control technology, enabling control of complex poses with six degrees of freedom. It boasts outstanding advantages such as high rigidity, high speed, and micron-level repeatability. The parallel structure ensures balanced force distribution, while lightweight moving parts combined with powerful actuators allow speeds of up to 2.2 m/s and achieve a repeat positioning accuracy of 0.8 μm.
Furthermore, the robot is equipped with an intelligent control system that supports intuitive programming and adjustment of complex motion paths. Its expandable parallel rod structure accommodates various configurations such as 3-axis, 4-axis, and 6-axis setups, adapting to different tasks, including Delta structures and Stewart platforms. The standardized interface design facilitates quick integration into various solutions.
In November 2025, the PLR robot successfully passed comprehensive testing and technical certification from an authoritative robotics testing institution. Its multiple core precision indicators have reached leading industry levels: the trajectory repeat positioning accuracy is 0.8 μm over a 1 cm working linear path, and the same accuracy holds for a distance of 20 cm. The robot’s repeat positioning accuracy in a working space distance of 10 cm exceeds 1 μm. This authoritative testing report not only quantifies the PLR robot’s “micron-level precision” but also provides robust data support and confidence for its large-scale application in ultra-precision operational scenarios.
Ruisong Technology’s high-precision high-speed robot is designed to break through bottlenecks in ultra-high-speed and ultra-precision operations in fields such as semiconductor packaging and precision electronic assembly. In the future, the company will continue to delve into core strategic areas such as semiconductors and ultra-precision manufacturing, expanding into high-growth markets like precision electronic manufacturing, flexible FPC assembly, optical fiber manufacturing, and wafer probe card manufacturing. The official launch of the PLR robot represents an important milestone in Ruisong Technology’s journey toward the localization of robotics and high-end manufacturing equipment. The company will continue to drive technological innovation, aiming to provide more efficient and reliable high-end robotic intelligent manufacturing solutions for global customers, supporting the advancement of Chinese manufacturing into higher segments of the global value chain.
