Currently, the embodied intelligence industry as a whole remains in a transitional phase from laboratory demo validation to small-batch commercial deployment. As the core actuating component enabling compliant physical interaction for humanoid robots, the technological maturity of humanoid force-controlled arms directly dictates the deployment progress of these robots. This field never lacks first movers, but few players can truly demonstrate stable delivery capabilities and pass the stringent validation of leading customers.
Although Rokae Robotics was not among the earliest to deploy humanoid force-controlled arms, it is now becoming the preferred choice for global leading humanoid robot companies advancing towards mass production, backed by its solid accumulation of industrial and force-control technologies.
Statistics show that, to date, cumulative shipments of Rokae's humanoid force-controlled arms have reached nearly 10,000 units. Among the top 20 domestic humanoid robot OEMs, over half have chosen to partner with Rokae.
Without seizing a first-mover advantage, Rokae quickly won the recognition of leading customers and achieved scaled delivery. Behind this "latecomer overtakes the pioneers" story in humanoid force-controlled arms lies an industrial logic often overlooked by many: the commercial deployment of embodied intelligence has never been about the speed of launching single-point concepts, but rather the depth of the underlying technology system and the maturity of the industrialization platform.
While the industry is still debating "who will build it first," the market is already voting with its feet, choosing industrial infrastructure providers that can truly deliver high quality, mature technological accumulation, full-stack in-house R&D, and an open ecosystem.
Why Are More and More Leading Embodied Intelligence Manufacturers Firmly Choosing Rokae's Humanoid Force-Control Solutions?
01. A Decade of Deep Cultivation in Force Control
For an embodied intelligence robot, spanning from algorithms to hardware, the industry chain involves several key aspects: AI algorithms and large models determine its "intelligence," while system integration and product definition dictate its "usability." Meanwhile, underlying capabilities such as joints, force control, and motion control determine its "mobility," as well as the precision of its movements, the safety of its interactions, and the stability of its operations.
Among these, underlying technologies require massive investments, feature slow iteration cycles, and exhibit strong economies of scale. If every team were to develop them from scratch, the industry would forever remain stuck in reinventing the wheel.
For Rokae, force control technology is the core field it has deeply cultivated for nearly a decade, and the company is also a core builder in this field. As early as 2016, when the industry was generally still adopting lower-threshold endpoint force control solutions, Rokae plunged into the more challenging technical route of full-joint force control. The company conducted comprehensive in-house R&D across the board, from underlying control algorithms to mechanical structure design, and from core components to system integration. In 2018, Rokae launched the first generation of flexible collaborative robots equipped with full-joint force control, taking the lead in transitioning this technology from the laboratory to industrial application.
From 2018 to 2026, Rokae has continuously deepened its focus on force-controlled arms. After nearly 10 years of continuous R&D innovation and industrial validation, tens of thousands of collaborative robots equipped with its in-house joint force control technology have been deployed across various industries, including automotive, 3C electronics, new energy, and metal processing. Operating 24/7 with long-term continuous stability, they serve sites including Hyundai, Toyota, Seres, Xiaomi, Valeo, and Foxconn, securing the number one position in shipments for the flexible collaborative force-controlled arm category.
Today, Rokae is building upon a decade of force control R&D achievements, transferring a complete suite of force control technology systems and engineering capabilities—validated in real industrial environments and continuously innovated and iterated—into its humanoid force-controlled arms. This not only supports 24/7 uninterrupted operation to collect massive amounts of high-quality real-world robot data but also withstands the stability tests required for deployment in real-world scenarios.
Within this force control system tempered by industrial scenarios, Rokae's Xuanji HSA Series Integrated Force-Control Joint serves as the underlying core unit.
At the hardware level, the HSA series integrates in-house high-precision torque sensors in each joint. Rokae has chosen to transfer mature, continuously iterated, and innovative solutions—validated in large-scale industrial scenarios—onto humanoid robots, eliminating the need to pay the "early adopter tax" for unproven hardware technologies amidst the industry's rapid development.
While hardware is the foundation of joint force control technology, the more critical aspect lies in closed-loop control at the algorithmic level. Combining over a decade of iterated force control algorithms, the HSA series boosts force control sampling to 16-32kHz at the joint level and maximizes the force control bandwidth to 50-200Hz, thereby achieving full-arm force perception and collision detection. Paired with 32kHz servo force closed-loop control, the underlying force sensor response bandwidth exceeds 500Hz, the joint torque closed-loop bandwidth surpasses 100Hz, and the dynamic force control accuracy is better than 0.5N.
Building on this, Rokae introduced the Taibai AR Series Humanoid Force-Controlled Arm, which fully extends joint-level force control capabilities to the entire system level. This means the robot is no longer limited to perceiving force only at its fingertips; instead, the entire arm possesses a sense of "touch," enabling the robot to serve as the foundational platform for interaction between embodied intelligence and the physical world through its force control capabilities.
Many humanoid force-controlled arms in the industry are customized for specific scenarios, resulting in non-standardized payloads, configurations, and interfaces.
From its initial design, the AR series has been positioned as a standardized actuating unit for embodied intelligence: featuring a 7-DOF humanoid configuration paired with a cross-axis humanoid wrist, built-in torque sensors in all joints, a system-level force control bandwidth exceeding 30Hz, and a force control resolution of less than 0.05N, it is fully capable of covering mainstream embodied scenarios such as precision assembly, flexible interaction, and impedance teleoperation. The entire series covers a payload range from 3kg to 20kg, achieves a payload-to-weight ratio of 1:2 across the lineup, and offers a maximum end-effector speed of 2m/s, complemented by designs such as hollow cable routing and IP54 industrial protection. It can be adapted for fixed dual-arm workstations as well as integrated into wheeled mobile robot platforms. For OEMs and algorithm teams, it functions more like a plug-and-play universal capability module. Without the need for repetitive debugging of underlying parameters, it can be rapidly integrated into their own products, which is also one of the core reasons why leading embodied intelligence users choose Rokae.
02. Full-Chain In-House R&D Defining Full-Stack Technical Standards
"Full-stack" is a buzzword in the current force control field, but the true value of many "full-stack" solutions on the market is actually questionable.
Many so-called full-stack solutions follow the route of "outsourcing core components + upper-level integration and packaging": for instance, procuring servo drives externally, with manufacturers only handling system assembly and application-layer algorithm debugging. While this model enables rapid prototyping and low costs, it inevitably falls short in terms of independent control and quality of underlying algorithms. These shortcomings become increasingly apparent during the scaling phase, particularly in responsiveness when facing the customized demands driven by the rapid development of the embodied intelligence industry.
Rokae's full-stack approach, however, ensures end-to-end independent control from the underlying hardware to the upper-level control system. It represents a complete technical architecture of "cerebellum + main body," with every core link firmly in its own hands.
At the main body level, the core force-controlled joint modules are entirely developed in-house, covering the entire process from high-precision torque sensors and high-performance servo drives to mechanical structure design. The hardware and algorithms are natively and deeply coordinated, eliminating the performance loss caused by multi-vendor adaptation, and ensuring precision consistency in mass production right from the foundational level.
At the cerebellum level, the in-house developed Xuanhe iNex Embodied Intelligence Control System builds an industry-oriented open "cerebellum" platform. iNex integrates force control and WBC (Whole-Body Control) capabilities, supporting collaborative operation with the AI "brain," and enabling different actuating units such as robotic arms, the waist, the head, and the mobile chassis to operate synergistically under a single controller.
More importantly, iNex is not a closed control system, but an open control foundation for industry partners. The entire platform provides standard interfaces such as ROS2, DDS, and SDK, enabling flexible adaptation to ecosystem peripherals like dexterous hands. It supports the rapid integration of various algorithm frameworks, computing platforms, and hardware modules, offering a more flexible secondary development environment for OEMs, algorithm teams, and application developers. Based on actual project estimations, this full-stack solution can help partners save 6 to 9 months in the underlying development cycle, boosting overall R&D efficiency by 30% to 50%.
For leading OEMs, this is the true value of a full-stack approach: rather than selling a pile of scattered hardware, it provides an out-of-the-box motion control foundation, eliminating the need to build the underlying system from scratch and allowing them to focus directly on upper-level scenario innovation and AI algorithm iteration.
03. Open Ecosystem Synergy Building Industrialization Infrastructure
The true weight of market validation is never found in press release promotions, but in actual deliveries and customers' votes.
The field is not short of claims like "tens of thousands of orders in hand" or "number one in a certain metric." However, only the actual number of products delivered to customers, passing acceptance tests, and being put into real-world use serves as the hard currency for measuring technological maturity and industrialization capabilities.
The selection process of leading manufacturers has always been the most stringent endorsement in the industry. They must comprehensively evaluate multiple factors, including technological maturity, delivery stability, integration difficulty, and subsequent iteration capabilities, all of which directly impact their own products' market competitiveness. To date, nearly 10,000 actual deliveries and adoption by over 70% of leading manufacturers stand as the most compelling proof of Rokae's technical capabilities.
This recognition is also evident at the industrial level.
Recently, Rokae, together with over 20 core industry chain enterprises including LinkerBot and XYZ Embodied AI, jointly initiated the establishment of the "China Embodied Intelligence Tier 1 Industry Alliance". This alliance brings together enterprises in key segments such as robotic arms, dexterous hands, computing power, and vision, promoting industry chain synergy and accelerating the systematic deployment of embodied intelligence from single-point innovation.
Rokae's role has never been that of a competitor in the end-market for humanoid robots, but rather an infrastructure builder in the era of Physical AI. Rokae has transformed its nearly decade-long accumulation of force control technology, motion control capabilities, and mass production manufacturing expertise into a standardized, open technology platform.
Currently, over 80 leading industry partners have chosen to confidently entrust the arm assembly to Rokae for mass production, with their products being continuously validated in an increasing number of real-world application scenarios. After all, as the core actuating component of the entire system, the fundamental value of the humanoid force-controlled arm has never been single-scenario deployment, but rather the scaled empowerment of the entire industry.
As an increasing number of professional players focus on building underlying capabilities and jointly construct an open and synergistic industrial ecosystem, the true large-scale deployment of the embodied intelligence industry will arrive even sooner.
Conclusion
The embodied intelligence field is never short of first-mover concepts, nor does it lack hype. However, as the industry progresses step by step from concept validation to commercial deployment, all the packaging will gradually fade away, and what ultimately matters is always hard-core strength.
From being a leader in force control during the collaborative robot era, to a core supplier in the humanoid force control field, and now an infrastructure platform builder for embodied intelligence, Rokae has never taken shortcuts to chase trends or grab attention. Time will ultimately prove that every "latecomer overtaking the pioneers" is essentially the result of profound accumulation leading to a powerful breakthrough; and every industry leader ultimately wins through the depth of its technological foundation.
Looking ahead, as the embodied intelligence industry moves into uncharted waters, the open and synergistic platform model will unleash even greater value. Only when underlying capabilities become public infrastructure will upper-level innovation truly explode, and Physical AI will genuinely permeate thousands of industries.
