Zero Err Funding Boosts Robotics Component Innovation

Shenzhen-based robotics innovator, Zero Err, has successfully closed a significant Series C extension funding round, injecting tens of millions of yuan into its operations. The capital infusion was led by prominent investment firms TH Capital and CDF Capital, signaling strong confidence in the company's trajectory within the rapidly evolving robotics sector. This strategic funding is earmarked for accelerating research and development initiatives, bolstering manufacturing capabilities, and expanding its international market presence.

Established in 2016, Zero Err has carved a niche by specializing in the design and production of high-precision, standardized robotic components. Its product portfolio prominently features the eRob series of robotic joint modules and the eCoder series of magnetic encoders. These advanced components are integral to a diverse range of robotic applications, including sophisticated industrial automation, cutting-edge surgical systems, and next-generation humanoid robots, underscoring the company's versatility and technological prowess.

The company's commitment to technological advancement is evident in its flagship eRob series. These modules boast a dual-encoder configuration, incorporating absolute encoders on both the motor and reducer output sides. This design achieves exceptional repeatable positioning accuracy of ±7 arc-seconds and absolute positioning accuracy of ±15 arc-seconds. Crucially, this closed-loop control system allows for real-time compensation of mechanical deviations, such as backlash and wear, ensuring sustained precision throughout the lifespan of robotic systems.

Zero Err's innovative approach is also demonstrated by its recent design breakthroughs, which have dramatically simplified the construction of complex robotic arms. For a 7-degree-of-freedom robotic arm, the company has reduced the component count from approximately 40 parts to just 10. This simplification not only streamlines assembly processes but also significantly lowers production costs, paving the way for the cost-effective mass production of humanoid robots, a key growth area for the industry.

The financial performance of Zero Err reflects its growing market traction. In 2025, the company experienced a more than doubling of its year-over-year revenue. While industrial and medical robotics currently form the bedrock of its sales, emerging applications in humanoid and AI-driven robots now contribute over 30 percent of revenue. These newer segments are anticipated to be the primary engines of growth in 2026, highlighting a strategic pivot towards future-facing robotic technologies.

This funding comes at a pivotal moment for the Chinese robotics market. Industry projections from Gongyan Industry Research Institute forecast a substantial expansion in demand for robotic joint modules, anticipating a rise from 2.24 million units in 2024 to 4.82 million units by 2030, potentially valuing the market segment at over 68.9 billion yuan (approximately $16 billion USD). Zero Err, already a leader in domestic robotic joint module sales with over 2,000 clients, is well-positioned to capitalize on this burgeoning demand.

Founder Jia Xiqing emphasizes a philosophy centered on delivering long-term value and reliability rather than engaging in price wars. The company's strategic preference for harmonic drive reducers in humanoid applications stems from their inherent advantages: compact form factor, reduced weight, high reduction ratios, and superior precision. This focus on quality and performance aligns with the broader industry trend towards more sophisticated and capable robotic solutions.
