Beijing Robotics Startup Linkerbot Raises Funds to Scale Dexterous Hand Production
Linkerbot has completed a Series A+ financing round raising several hundred million yuan (tens of millions of dollars) to accelerate the mass production of dexterous robotic hands. The funding serves as a critical endorsement of the company’s role in the supply chain for embodied artificial intelligence and humanoid robotics.
The investment round attracted a consortium of backers, including Zhejiang Innovation Investment, Deqing Industrial Investment, Leju Robot, CDH Investments, Smith New Material Technology, Dongfang Precision, AUX, Huafu Investment, Hongyi Fund, Hongshan Capital, and Xiangyuan New Material. The capital injection aims to consolidate the company’s manufacturing capabilities as it addresses the growing demand for high-performance end-effectors in the robotics sector.
Linkerbot reports that it has become the sole entity globally to achieve mass production of high-degree-of-freedom (DOF) dexterous hands at a scale of 1,000 units. The company claims to hold over 80% of the global market share for high-DOF hands, covering tendon, direct drive, and linkage technologies, with monthly orders now exceeding 1,000 units.
The financing comes as the humanoid robot industry experiences rapid expansion, driving the need for reliable, cost-effective components. By scaling its production capacity, Linkerbot intends to mitigate the high costs typically associated with dexterous manipulation hardware, aiming to support broader industrial and commercial application scenarios.
Scaling Manufacturing Capabilities
The company’s flagship product, the Linker Hand L20, features 21 degrees of freedom and is available in both general and industrial versions. It is designed to meet the full range of industry requirements, from algorithm development to practical application. To further complement its industrial portfolio, the company has introduced the Linker Hand L6, completing its “Industrial Master” product line.
Central to these products is the company’s proprietary “Super Electric Cylinder” technology. This drive system utilizes a “brushless motor + ball screw” scheme, achieving a drive efficiency of 90%—twice the level of traditional industry products. The system delivers a screw end thrust of 200N and has a tested lifespan exceeding one million cycles.
Product Diversification and Efficiency
Responding to the surge in mid-sized robot development, Linkerbot has released the Linker Hand O6. Weighing only 370 grams, it is currently the lightest dexterous hand globally, designed to redefine lightweight limits and significantly reduce end-effector load. The product aims to disrupt traditional cost structures through high performance-to-price ratios. A "Lite" version of the Linker Hand O6 has also been launched to make the technology more accessible across the industry.
Software and Data Ecosystem
Beyond hardware, the company is building a comprehensive software ecosystem to support robotic learning. Linkerbot introduced the Open TeleDex modular teleoperation system, which employs a “TripleAny” architecture compatible with any external device, robotic arm, or dexterous hand. This open system aims to lower the costs associated with setting up dexterous operation data collection.
Furthermore, the company has developed the LinkerSkillNet multi-modal data collection system to build a global library of dexterous operation skills. Complementing this is the Dex-Serl real-machine reinforcement learning framework, which integrates end-effector force perception and automated auxiliary motion algorithms to enhance the automation of model training.
Strategic Roadmap and 2026 Targets
Looking ahead, Linkerbot is advancing its "Lingchuang Qiaojie" strategy, which extends the concept of robots manufacturing robots to "self-evolution." This entails creating an ecosystem where robots can continuously learn and create new skills independently.
The company has outlined aggressive delivery targets, planning to deliver between 50,000 and 100,000 dexterous hands in 2026. This scaling targets the full implementation of dexterous manipulation in the global robotics industry, positioning the company as a key enabler of next-generation robotic capabilities.
