The world of humanoid robotics is rapidly transitioning from the realm of science fiction into reality. As pioneers like Tesla unveil extraordinary prototypes, such as their Optimus robot—which recently showcased impressive dexterity by catching a thrown tennis ball—the anticipation surrounding humanoid robots continues to build. Manufacturers, including emerging startups like MagicLab, have already begun training their humanoid robots in factory environments, signaling a significant step toward mass production and application in a variety of sectors. Experts project that by 2025, humanoid robots may reach their performance maturity, reshaping industries in ways we can only imagine.

One of the key features of humanoid robots is their dexterous hands, which mimic the intricate movements of human fingers. This precision is essential for tasks requiring fine motor skills. The anatomical design of these robotic appendages is inspired by the kinematics of the human hand, although various manufacturers have opted for simplified models to ease manufacturing complexity. For instance, while a single human hand comprises 21 degrees of freedom, Tesla's design limits this to just 11. This simplification helps to streamline production processes while still allowing for considerable functionality.

A crucial component in the development of these humanoid robots is the hollow cup motor, known for its lightweight, low energy consumption, and precise control capabilities. Leading companies in the electric motor industry, such as Mingzhi Electric and Zhaowei Electro-Mechanical, are capitalizing on these advantages by integrating hollow cup motors into their dexterous hand models. By successfully coupling these motors with precision gearboxes, encoders, and sensors, they produce robotic hands that exhibit remarkable flexibility.

From a global market perspective, the humanoid robotics sector represents a multi-billion dollar opportunity. Major international players like Switzerland’s Maxon, Germany’s Faulhaber, and Switzerland’s Portescap dominate the hollow cup motor market, holding a substantial 70-80% share. As the demand for humanoid robots rises, projections indicate that the market for hollow cup motors could burgeon to between 2.9 billion to 12 billion yuan depending on sales figures. Domestic firms are also pushing to exploit this growth by entering the humanoid robotics space.

Mingzhi Electric, known for its micro-control motor technology, is one of the frontrunners in this industry. Despite achieving a revenue of 2.96 billion yuan in 2022, the company has faced challenges over the past two years as growth has stalled. By the end of the first three quarters of 2024, the company reported revenues of 1.83 billion yuan—a decline of 4.51% year-over-year. However, its strong position in the micro motor sector, particularly as a leading producer of stepper motors, positions it favorably in the competitive landscape. The company has broken the stronghold held by Japanese manufacturers and gained recognition from over 220 institutions as a leading provider of hollow cup motors, crucial for humanoid robot hands.

Furthermore, as a supplier to Tesla, Mingzhi Electric is on the cusp of receiving production orders, potentially elevating it to a primary supplier for this pioneering technology.

In contrast, Zhaowei Electro-Mechanical showcases a different path to success. With a focus on the micro-drive sector, the company has developed an integrated product system encompassing precision molds and micro-drive systems tailored for a wide range of applications, including automotive electronics and industrial automation. It enjoys strong collaborations with major automotive brands such as BYD and Bosch, helping ensure consistent revenue growth from this sector.

Since 2020, Zhaowei has consistently reported yearly revenues of around 1.2 billion yuan, with projections for the first three quarters of 2024 revealing a remarkable growth trajectory—a 29.99% increase year-over-year to 1.057 billion yuan. Their competence in the market and the ongoing shift towards electric vehicles are expected to further bolster their automotive electronics division, ensuring more than 30% revenue expansion annually.

Notably, while Zhaowei's net profit margins are improving—recording 15.05% in 2024—Mingzhi's margins have been in decline, falling to just 2.62%. Financially, Zhaowei appears to be in an advantageous position for investments into humanoid robot development.

Looking ahead, Zhaowei has also continued to innovate in micro motor technology, recently launching several models suitable for humanoid robotics, including micro brushless hollow cup motors. Their ability to combine core components like gearboxes, high-performance motors, and electronic control systems already resulted in successful development of bionic robotic hands.

Both Mingzhi Electric and Zhaowei Electro-Mechanical demonstrate the rapid evolution and potential in the humanoid robotics sector. With major enterprises like Tesla, Huawei, and Xiaomi vying for dominance, the landscape is competitive yet ripe for innovation and investment. Domestic manufacturers are poised to leverage their technological advancements and market positioning, providing the backbone necessary for the growth of the humanoid robot industry within China.

The advancements in humanoid robotics mark a significant turning point in technological development, promising to revolutionize not only factories and industries but also everyday life. As we advance further into this realm, the implications extend beyond mere commercial success; they touch upon the very nature of work and interaction in human society. Thus, the path towards a world where robots can effectively take on human-like roles in labor and daily tasks becomes increasingly plausible.
