HardcoreKr has learned that Shenzhen Nuoshi Robot Co., Ltd. (hereinafter referred to as "Nuoshi Robot") recently completed an angel round of financing of tens of millions of yuan. This round of financing is jointly led by Chengwei Capital, K2VC, and Plug and Play China. Fenghe Capital serves as the long-term strategic financial advisor. The funds will be used for product delivery, business expansion, and talent recruitment.

"Nuoshi Robot" was established in July 2023. The company focuses on the design, production, and manufacturing of planetary roller screws and supporting actuator modules. It has set up a research and development center in Shenzhen and has a production and manufacturing base in Shanghai.

The founder, Xu Yang, graduated with a master's degree in Mechanical Manufacturing from Tongji University. Together with the co-founder, Wang Xiaobin, who used to work in a Fortune 500 automotive parts company, they possess a world-class enterprise management perspective and experience. The co-founder, Wang Xiaobin, is a successive successful entrepreneur who once led a start-up team from scratch to the Pre-IPO stage. The core technical member of the founding team and the well-known expert in the thread technology field, Professor Xu Genlin, used to be a professor at Shanghai University. He has been deeply engaged in the field of mechanical manufacturing technology for nearly 50 years, with both theoretical and practical production experience.

Nuoshi Robot's Shanghai Production Base

The planetary roller screw is a high-precision and high-performance transmission device that adopts a compact planetary gear structure. The overall device is small in size and is convenient to be integrated into equipment with limited space.

Due to the load-bearing distribution of the planetary gears, the planetary roller screw can withstand a large axial force and is suitable for heavy-duty working conditions. Compared with the ordinary roller screw, the suitable load of the planetary roller screw is about 3 to 5 times that of the ordinary roller screw, and its service life is also as high as 15 times. It is mostly applied in various precision machinery and automated equipment in the fields of industrial manufacturing, aerospace, medical equipment, and military.

However, due to the relatively high manufacturing process and technical requirements of the planetary roller screw, involving multiple complex links such as high and low temperature aging treatment and quenching, the cost is also relatively high. In the past, companies such as Rollvis, GSA, and Ewellix occupied the main market in China, and there is a broad space for domestic substitution.

Noticing this market, "Nuoshi Robot" has developed the world's smallest planetary roller screw based on innovative technology and the underlying mold design and production capacity. Its screw diameter is only 2mm, and the nut diameter is 6mm, which can greatly increase the space utilization rate of the linear actuator, providing a linear actuator solution for precise control in narrow spaces such as dexterous hands, and solving problems such as poor rope drive life, low trapezoidal screw efficiency, and insufficient connecting rod load.

Nuoshi Initiates the World's Smallest Planetary Roller Screw

"Nuoshi Robot" adopts a unique high-precision metal forming process, which can meet the G5 precision of the planetary roller screw for stable mass production, achieve the production and delivery of high-strength, high-durability, and high-precision products at low cost, and provide a reliable solution for the mass production of the embodied robot industry, the automotive and intelligent manufacturing industry.

Taking the humanoid robot scene as an example, the planetary roller screw plays a key role in its joint transmission. By converting rotary motion into linear motion, it can provide stable and precise power transmission for the joints of the humanoid robot, complete more accurate and smooth joint movements, thereby simulating various human actions such as walking, running, and jumping.

Humanoid Robot Using Inverse Planetary Roller

In the field of intelligent driving, the planetary roller screw can be used to achieve high-precision positioning and steering control. Through the transmission of the planetary roller screw, it helps the autonomous driving system accurately control the driving direction and position of the vehicle to ensure that the vehicle can travel according to the predetermined route and speed; at the same time, the planetary roller screw is also widely used in sensors and actuators in intelligent driving. For example, it ensures that sensors such as lidar and cameras can accurately point to the target area and capture clear image data.

At present, the commercialization of "Nuoshi Robot" is progressing steadily. It has completed the landing and batch shipments in multiple xifen fields, covering humanoid robot dexterous hands and limb linear actuators, lithium battery coating equipment, medical equipment, welding manipulators, automotive brake EMB systems, high-precision optical equipment positioning, and industrial machine tools. The company's products have been affirmed by industry-leading customers.

Planetary Roller Screw Linear Actuator Humanoid Application Scenario

Investor's Perspective:

Chengwei Capital The project leader said that Chengwei Capital continues to focus on the targets of core components of intelligent manufacturing and continuously explores and assists the growth of a new generation of core component enterprises in this field. The planetary roller screw has a wide application space in multiple fields, and the local supply market has a large space and clear demand. But at the same time, the domestic planetary roller screw relies on imports, and the related processing equipment also faces the risk of being stuck. With years of technical accumulation, the Nuoshi team provides an efficient and large-scale processing method for the industry, which is an important breakthrough in the independent and controllable industrial chain. From the perspective of the trend of localization of core devices and the demands of emerging industry support, we firmly believe in the development and growth of Nuoshi and the new generation of domestic core component enterprises, and continue to promote the upgrading of the domestic manufacturing industry, becoming an important engine to promote the development of new-quality productive forces.

K2VC Partner Zhao Yang said that K2VC firmly believes in the big wave of the replacement of oil cylinders with electric cylinders. The Nuoshi Robot team has decades of accumulation and inheritance of high-precision cold forming technology, and has made significant breakthroughs in the production cost, efficiency, and precision of the planetary roller screw. It is one of the few experts in the industry that truly has mass production capacity. Its roller screw and electric cylinder products have been verified and batch-shipped in front of many industry-leading customers in lithium battery equipment, precision medical devices, automobiles, humanoid robots, and other industries. We expect Nuoshi Robot to further consolidate its market position and accelerate the electrification and intelligent transformation and upgrading of actuators with its technical product advantages.

Plug and Play China Fund Partner Zhu Xiaowen said that the Nuoshi team is a rare team with both a deep theoretical foundation and rich engineering experience. Their various types of planetary roller screws make up for the lack of domestic supply in the domestic high-end screw market, and are expected to change the current situation where the market is dominated by German and Japanese enterprises; in the past, due to the limitations of factors such as precision, cost, and processing efficiency, the development has been restricted. The Nuoshi team has successfully overcome technical difficulties through unique process research and development, material processing, and mold design. With Plug and Play's in-depth understanding of the industrial equipment, automotive braking, and humanoid robot industries, we have found that there is a huge development potential in the downstream application market of the planetary roller screw. We believe that the Nuoshi team can lead this xifen industry into the fast lane.
