Inspire Robots: Dual-Engine Growth with Dexterous Hands and Miniature Servo Cylinders Breaks Bottlenecks in Precision Motion Control

In recent years, robots have been accelerating their penetration into industries such as manufacturing, healthcare, and services, driving a continuous rise in demand for high-precision motion control. According to data from QY Research, the global market size for precision motion systems was approximately USD 801 million in 2024 and is projected to reach USD 1.309 billion by 2031, representing a compound annual growth rate (CAGR) of 6.8% from 2025 to 2031. Driven by applications in humanoid robots and high-end medical devices, the market exhibits significant growth potential; however, in scenarios such as micron-level assembly and millimeter-level surgical procedures,Low domestic production rates, reliance on imports, and high costs have become the “chokepoint” bottlenecks hindering the large-scale development of the robotics industry.

In 2016, Beijing Inspire Robots Technology Co., Ltd. (hereinafter referred to as “Inspire Robots”) was officially established,Betting on the R&D and manufacturing of micro-precision motion components characterized by "miniaturization, integration, and flexibility," as well as breakthrough innovations in servo control technology. Facts have proven this direction to be correct: data from the International Federation of Robotics (IFR) shows that global industrial robot installations decreased by 3% year-on-year in 2024,China, however, saw a 5% growth against the trend,The installed base has reached 290,000 units, accounting for 54% of the global total. The demand for localization of precision components has become one of the key drivers propelling industry development.

Ten years later,INSPIRE-ROBOTS, leveraging its independently developed core technologies of miniature servo electric cylinders and five-fingered dexterous hands, has not only pioneered the commercial mass production of five-fingered dexterous hands but also broken import monopolies in high-precision scenarios such as semiconductors and new energy.The product has entered the supply chains of leading companies such as CATL, Zhiyuan, and Unitree.Annual Shipments Exceed 10,000 UnitsFrom laboratory prototypes to industry benchmarks, INSPIRE-ROBOTS is steadily advancing China’s intelligent manufacturing in the field of precision motion control through micron-level innovations.

INSPIRE-ROBOTS’ breakthrough began with a reverse selection.

In 2016, amidst the domestic robotics industry’s fervor for complete robot development, the company dedicated its full efforts to the research and development of robotic components such as micro servo electric cylinders and dexterous hands. The team keenly recognized that as rotary joint technology matured,Linear Actuators Remain the Industry’s Invisible Weak Link, and miniaturized moving components will become the key foundation for next-generation robots.

As of now,INSPIRE-ROBOTS Has Completed Multiple Rounds of Financing, with investors including well-known institutions in the hard-tech sector such as Fortune Capital, Shenzhen Capital Group, and CICC Capital, whose substantial financial commitments validate its value in “filling industrial gaps.”

Previously, INSPIRE-ROBOTS had publicly stated that,In 2024, its overseas business grew 20-fold, with a compound annual growth rate (CAGR) in revenue exceeding 100%., North America, Japan, and South Korea have become key markets.“Price wars are inevitable, but the ultimate competition still hinges on product strength.”As the team stated, INSPIRE-ROBOTS’ ten-year growth has validated this logic: capital will ultimately flow toward technological innovations that address real industrial pain points.

Starting from a laboratory in Zhongguancun and entering the global supply chain, INSPIRE-ROBOTS has precisely seized the critical juncture of the robotics industry’s upgrade from “complete machine integration” to “core components,” becoming a microcosm of the positive interaction between hard-tech entrepreneurship and capital.

“Miniaturization, integration, and flexibility” are gradually becoming industry consensus. Integrated actuators, sensors, and dexterous hands have replaced the traditional “big three” (motors, reducers, and servo drive control) as the core standard configuration for robots. This trend is inseparable from the persistence of early explorers.

INSPIRE-ROBOTS is a prime example. Since 2016, the team has been firmly committed to this direction,Focusing on Two Core Products: Micro Servo Electric Cylinders and Humanoid Five-Fingered Dexterous Hands, filling market gaps through independent R&D and driving the industry from “discrete solutions” toward “integrated precision execution.”

The miniature servo electric cylinder is a product that fills a gap in the market; even the name “miniature servo electric cylinder” was coined by INSPIRE-ROBOTS.As a brand-new all-in-one linear actuator product, it integrates a coreless motor, high-precision planetary gearbox, miniature planetary roller screw, sensors (position and force sensors), and a servo drive controller. It achieves integrated drive and control in a more compact form factor, featuring technical advantages such as small size, high precision, and high load capacity, enabling precise servo control at any position within the stroke range.

Compared with traditional linear actuation solutions, its advantages are particularly prominent: INSPIRE-ROBOTS has achieved structural innovation in miniature servo electric cylinders by adopting an “integrated drive-and-control” design, which compactly integrates the motor, reducer, sensors, and controller into a miniature module with a diameter of only ten-plus millimeters—akin to stuffing an “elephant” into a “matchbox.” The BLA series products offer a repeatable positioning accuracy of up to ±2 µm (approximately 1/30 the diameter of a human hair) and feature hybrid position-force control, enabling real-time adjustment of pushing and pulling forces during applications.Addresses the industry pain points of traditional solutions: “bulky size and difficult precision control.”

Currently,Micro servo electric cylinders have formed a product matrix combining standardization and customization, covering five major series: LA, LAS, LAF, LASF, and BLA., with the lightest model weighing only 21g and capable of delivering approximately 100N of push-pull force. The BLA series is specifically designed for high-precision industrial equipment, achieving an accuracy of ±2μm, and has been widely applied in equipment and processes such as closed-loop coating for new energy lithium batteries, battery testing, and tab welding.

As the smallest micro precision servo motion component on the market, the micro servo electric cylinder can also be applied in fields such as high-end medical care, new energy, and 3C semiconductors, facilitating the intelligent upgrading of instruments, equipment, and tooling fixtures.

In the fields of healthcare and medical aesthetics,Team Introduction: The technology has been applied in gold microneedling, hair transplantation, minimally invasive surgery, and injection devices, significantly optimizing needle puncture precision, hair follicle survival rate, and thrust error. With their compact size, lightweight design, and precise controllability of position and speed, miniature servo electric cylinders naturally meet the component requirements of medical devices and have been widely used in minimally invasive surgical instruments, surgical robots, IVD equipment, and other medical devices.

The humanoid five-fingered dexterous hand developed by INSPIRE-ROBOTS uses miniature servo electric cylinders as motion actuators (integrated linear joints), featuring 6 active degrees of freedom and 12 motion joints, capable of performing fine movements such as grasping and twisting., has launched five series including RH56F1, RH56E2, and RH56DFX, which are applied in fields such as humanoid robots, scientific research, and prosthetics.

Prior to 2020, China's dexterous hand market relied heavily on imported products such as those from Shadow Robot Company. These devices were generally heavy and priced as high as one million yuan, limiting their use to scientific research applications.INSPIRE-ROBOTS’ five-fingered dexterous hand weighs a mere 540 grams, approximately 80% lighter than imported products, and is priced at only one-tenth that of comparable international offerings., it can simulate human hands to perform complex actions and precise grasping, such as playing the piano, brewing tea, and playing rock-paper-scissors, breaking the import monopoly.

“We aim to develop a dexterous hand capable of operating in real-world scenarios,” said Fang Hainan, CMO of INSPIRE-ROBOTS. The single-arm payload capacity of humanoid robots typically does not exceed 5 kg, and a 3 kg dexterous hand accounts for nearly 60% of this limit, making it difficult to perform high-payload tasks. Furthermore, the gripping force and precision of the dexterous hand significantly impact its performance. Gripping force, analogous to human hand strength, correlates with greater manipulation capability. Meanwhile, integrated force and position sensors ensure execution precision and controlled gripping force, enabling the delicate handling of fragile items such as eggs and strawberries without damage.

Furthermore, the use of miniature servo electric cylinders as the core actuation source for dexterous hands has significantly simplified their mechanical complexity."Independent replacement of each joint can be achieved."“Customers can simply open the casing and replace the electric cylinder, restoring it to like-new condition,” significantly reducing after-sales maintenance costs for dexterous hands.

Leveraging its lightweight design and high adaptability, INSPIRE-ROBOTS’ dexterous hands are transitioning from “niche experiments” to “widespread adoption.” Initially, they primarily served academic research and prosthetic applications, addressing the challenges of high costs and procurement difficulties associated with imported products. Today, they have become a long-term partner for leading enterprises in the humanoid robotics industry.In medical and healthcare settings, it will be applied in hospital navigation and elderly care, with plans to further expand into disability care., to alleviate the increasingly severe shortage of nursing staff.

According to INSPIRE-ROBOTS, annual sales of dexterous hands were only in the hundreds during the initial commercialization phase, but with the explosive growth in demand for humanoid robots,Order volume surged significantly in 2024, with annual deliveries nearing 2,000 units, while sales in the first half of 2025 alone exceeded 4,000 units.Since achieving commercialization in 2020, sales of miniature servo electric cylinders have continued to grow, with volume expected to exceed 100,000 units in 2026.

Overall, from micro servo electric cylinders to humanoid five-fingered dexterous hands, INSPIRE-ROBOTS has always been grounded in “in-house R&D of core components,” breaking through the “zero-to-one” technological gaps in products such as miniaturized linear actuators and lightweight dexterous hands.

As mentioned by the CMO in the interview,INSPIRE-ROBOTS’ commercialization process has always been closely aligned with “addressing customers’ real needs.”, from entering medical scenarios to providing modular components for humanoid robot companies, and further expanding into new energy and precision manufacturing, INSPIRE-ROBOTS continuously drives product iteration based on real-world demands,Gradually building out four major application sectors: healthcare, robotics, new energy, and precision manufacturing, and form a virtuous cycle of “technology R&D – scenario implementation – large-scale mass production.”

Despite rapid market growth, the industry continues to face challenges from low-price competition and overseas certification barriers. INSPIRE-ROBOTS has chosen to mitigate these risks through sustained R&D investment, continuously iterating its two core product lines: electric cylinders and dexterous hands. Its offerings have evolved from the BLA series with ±2μm precision to high-load electric cylinders exceeding 500N, and from lightweight dexterous hands to upcoming high-degree-of-freedom new models, thereby steadily expanding into application scenarios such as healthcare and elderly care.

“The key to the industry is to jointly expand the demand pie.”CMO Fang Hainan’s perspective articulates INSPIRE-ROBOTS’ ecosystem logic: reducing the production and maintenance costs of dexterous hands through modular design, spreading R&D and manufacturing expenses via the scaled mass production and application of miniature servo electric cylinders, and driving the industry from “zero-sum competition” toward “value co-creation.” This open stance is attracting more upstream and downstream enterprises to join in building the precision motion control ecosystem.

The story of INSPIRE-ROBOTS is a microcosm of China’s hard-tech entrepreneurship: starting from a niche sector, it has gradually leveraged deep technological expertise and market insights to penetrate the global market. As Fang Hainan stated, “We do not build robots for the sake of building them; we do so to solve real-world problems.”

In the era of intelligence, mastering precision control technology for core components is a critical pathway to advancing robotics technology. INSPIRE-ROBOTS is steadily progressing along this path.
