Human hands are extraordinary tools—remarkably flexible and laden with nerves, they represent the peak of anatomical complexity. Everyday tasks that most people perform without a second thought, like tying shoelaces or fastening buttons, necessitate intricate neurological commands and precision movements. Throughout history, no machine has been able to replicate the finesse of human hands, considered the most adept appendages of our anatomy.
However, as advancements in artificial intelligence (AI) accelerate, several companies, particularly in China, are on the verge of overcoming this monumental challenge in the realm of robotics.
A fresh wave of Chinese start-ups is harnessing the nation’s robust manufacturing capabilities and governmental backing for “embodied AI” to create fully dextrous robotic hands. Such technology could transform humanoid robots from mere entertainment into valuable tools for everyday use.
Since the introduction of Unitree's dancing humanoids at the 2025 Spring Gala—an annual variety show broadcast during the Lunar New Year—public interest in robotics has skyrocketed in China. Industry leaders and policymakers view advancements in robotics as a pathway to bolster the country's economic prospects amid an aging and dwindling workforce. Promotional materials from robotic firms highlight their products capable of handling tasks like laundry, cooking, and hairstyling.
In May, a report in Qiushi, the Chinese Communist Party's theoretical journal, underscored the significance of "embodied AI" in China's development strategy, asserting that “embodied-intelligence robots” have the potential to create expansive new markets worth trillions of yuan.
Yet, while China leads the world in robot deployment—over half of newly installed factory robots are situated within its borders—the applications for humanoid robots remain limited. The International Federation of Robotics noted last September that “true multipurpose humanoids are still far off.”
This limitation exists primarily because many of the practical tasks requiring humanoids necessitate human-like dexterity. Crafting such hands poses significant engineering challenges. Elon Musk, founder of Tesla and creator of the Optimus humanoid, remarked last year that robotic hands embody the “majority of the engineering difficulty” involved in building a robot.
Zhou Yong, founder of LinkerBot—a prominent player in the dextrous hand sector—articulates these challenges in a lab filled with a variety of robotic hands. He states that developing a robotic hand is "one hundred times more difficult" than creating a full humanoid, citing that the dexterity of hands far exceeds other body parts, yet occupies a relatively smaller volumetric space.
Zhou, driven by the success of American innovators, decided to dedicate his focus solely to creating robotic hands after a distinguished academic career at Huazhong University of Science and Technology. He founded LinkerBot in 2023, where the company produces around 5,000 hands monthly and aims to double that output, with a goal of reaching a valuation of $6 billion. He sees human hands as essential for replicating various human abilities. Zhou aims to manufacture affordable prosthetic hands for amputees, targeting a price of approximately $1,000, which could drastically reduce current costs.
Creating these robotic appendages involves solving intricate hardware and software challenges. The advantages of China's sophisticated and cost-effective manufacturing ecosystem have enabled numerous firms to advance rapidly in the hardware domain. The boom of China's electric vehicle sector has contributed to the availability of components essential for robotics, from batteries to specialized motors.
Pan Yunzhe, founder of Wuji Technology, a Shenzhen-based company specializing in robotic hands, highlights that the ease of sourcing components influenced his decision to establish his business in China rather than the U.S., where he faced supply chain hurdles.
Despite the burgeoning number of robotic companies in China—now exceeding 1 million with a 40% increase in registrations from the previous year—start-ups focused on hand technology are still a nascent segment. In 2024, the market for dextrous hands in China surpassed 50 billion yuan ($7.4 billion), a significant increase from 13 billion yuan the year before.
Pan emphasizes the importance of manipulative capability over locomotion, insisting that humanoids must grasp tools effectively to be genuinely useful. However, the more daunting challenge lies in developing the software needed to instruct these hands.
Experts like Nathan Lepora, a robotics and AI professor at the University of Bristol, acknowledge that while hardware advancements progress, controlling these dextrous hands is a highly complex challenge yet to be mastered.
Many firms are working on teleoperating these hands to gather large datasets necessary for training spatial intelligence models. Unlike large language models that can leverage vast amounts of textual data, the 3D modeling space lacks such rich sources. Efforts to gather relevant data include having researchers use sensor-equipped gloves to record subtle movements and pressures that contribute to dexterous tasks—skills that remain elusive for machines at present.
To address these challenges, Wuji's flagship product, the Wuji glove, is designed to capture intricate movement data and pressure sensitivity, simulating activities like cracking an egg or handling delicate items—abilities that robotics have not yet mastered.
The journey to replicating human-like manipulation continues to unfold, and many Chinese entrepreneurs remain optimistic about their potential to innovate in this field. Zhou of LinkerBot envisions a future where factories of robotic hands could autonomously produce more robotic hands, forming a self-sustaining system with minimal human intervention. Ultimately, he believes that the goal isn’t to replace human labor but to enhance quality of life and foster prosperity through robotics.
