Unitree Robotics (宇树科技), officially Hangzhou Unitree Technology Co., Ltd., is a Chinese robotics company headquartered in the Binjiang District of Hangzhou, Zhejiang Province. Founded in August 2016 by Wang Xingxing (王兴兴), the company designs and manufactures quadruped and humanoid robots at price points far below those of Western competitors. Unitree has become one of the world's leading producers of legged robots, accounting for 69.75% of global quadruped robot sales by volume in 2023 according to the Gaogong Robotics Industry Research Institute (GGII). As of March 2026, the company has filed for an initial public offering on the Shanghai Stock Exchange's STAR Market, seeking to raise approximately 4.2 billion yuan (roughly $610 million).
The origins of Unitree trace back to 2013, when Wang Xingxing enrolled at Shanghai University to pursue a master's degree in mechatronics engineering. Born in 1990 in Ningbo, Zhejiang Province, Wang had earned his bachelor's degree from Zhejiang Sci-Tech University. During his postgraduate studies, Wang became captivated by quadruped locomotion and spent approximately 20,000 yuan developing a prototype quadruped robot called XDog for his graduation thesis. The XDog project attracted significant attention from both domestic and international technology media, generating widespread interest in the global robotics community.
After graduating in 2016, Wang briefly joined DJI, the Chinese drone manufacturer. He resigned after only two months when interest in XDog brought potential buyers and investors to his doorstep. On August 26, 2016, Wang registered Hangzhou Unitree Technology Co., Ltd. in a modest 50-square-meter office in Binjiang District, Hangzhou.
In 2017, Unitree released its first commercial product, a quadruped robot called Laikago, named after Laika, the Soviet space dog that became the first animal to orbit the Earth. Compared to the XDog prototype, Laikago featured improved mechanical design, more powerful motors, and better stability. The product attracted attention from universities and research institutions looking for an affordable quadruped platform.
Unitree continued iterating on its quadruped designs with the release of AlienGo in 2019 and the A1 in 2020. However, it was the launch of the Go1 in June 2021 that catapulted the company into mainstream awareness. Priced from just $2,700 for the Go1 Air variant, the Go1 was billed as the world's first intelligent quadruped robot available to consumers for under $3,000. The robot featured five wide-angle stereo depth cameras, ultrasonic sensors, and a 16-core CPU plus GPU processing system. The Go1 could run at speeds up to 4.7 m/s and weighed just 12 kg, making it highly portable.
The Go1 attracted comparisons to Boston Dynamics' Spot, which at the time sold for $74,500. While Spot offered superior ruggedness, payload capacity, and industrial-grade autonomy features, the Go1 delivered surprisingly capable locomotion and sensing at a fraction of the cost. This pricing strategy established Unitree's core competitive identity: bringing advanced legged robotics to mass markets through aggressive cost reduction.
In July 2023, Unitree unveiled the Go2, its next-generation consumer quadruped robot. Starting at $1,600 for the Air variant, the Go2 featured Unitree's self-developed 4D LiDAR L2 sensor with 360-by-96-degree hemispherical recognition, a minimum detection distance of just 0.05 meters, and integration with GPT-based large language models for natural voice interaction. The Go2 weighed 15 kg and could reach speeds of 2.5 m/s while carrying up to 7 kg of payload.
Unitree made its first move into humanoid robots in 2023 with the unveiling of the H1. Standing 180 cm tall and weighing 47 kg, the H1 was a full-size humanoid designed as a research and industrial platform. Priced at approximately $90,000 for the base model, the H1 delivered peak joint torque of 360 N·m at the knee and was powered by an 864 Wh quick-swap battery providing 1.5 to 2 hours of runtime. The robot featured 3D LiDAR with 360-degree spatial mapping and an Intel RealSense D435i depth camera.
The H1 gained global attention when it set a world record for bipedal running speed among full-size humanoid robots, achieving 3.3 m/s (approximately 7.4 mph or 11.9 km/h). This record demonstrated Unitree's rapid progress in bipedal locomotion control.
In August 2024, Unitree launched the G1, a compact humanoid robot that began at a starting price of $16,000 and quickly went viral across social media. Standing between 127 and 132 cm tall and weighing 35 to 47 kg depending on the configuration, the G1 was dramatically more affordable than any comparable humanoid on the market. The base model offered 23 degrees of freedom, while the top-tier EDU Ultimate configuration expanded to 43 degrees of freedom through the addition of dexterous hands (7 DOF per hand), extra waist axes, and wrist joints. The G1 could walk at 2 m/s, produced joint torques up to 120 N·m, and carried a battery providing roughly 2 hours of operation.
Unitree manufactures both quadruped and humanoid robots across consumer, research, and industrial segments. The following table summarizes the company's major product lines.

The G1 became Unitree's breakthrough product and arguably the most talked-about humanoid robot of 2024 and 2025. Its combination of low price, compact form factor, and impressive physical capabilities made it a sensation on social media platforms worldwide.
The G1 is available in 14 configurations, ranging from the G1 Basic at around $21,600 to the G1 EDU Ultimate D at approximately $73,900. (The initial promotional starting price of $16,000 was later adjusted as production models reached the market, with the base price settling at approximately $13,500 by early 2026.) The robot can be optioned with articulating, force-controlled three-fingered hands that include tactile feedback. It processes sensor data through an 8-core high-performance CPU and features 3D LiDAR alongside Intel RealSense D435 cameras.
Unitree's G1 robots starred in the 2026 Spring Festival Gala, one of the most-watched television broadcasts in the world. During the performance, dozens of G1 units executed a fully autonomous kung fu routine that included Drunken Fist movements, nunchaku techniques, and parkour sequences. The performance set multiple world firsts for humanoid robots, including continuous freestyle table-vaulting parkour, aerial flips reaching approximately 3 meters in height, and a two-step wall-assisted backflip. The robots ran at speeds up to 4 m/s (roughly 14 km/h) during the routine. The performance went viral on Weibo and WeChat, pushing "Humanoid Robots" to the top of trending lists, and the broadcast attracted an estimated 23 billion views across platforms.
Following the Spring Festival Gala appearance, Unitree saw a surge in orders. CEO Wang Xingxing announced targets of between 10,000 and 20,000 humanoid robot shipments for 2026, up from the approximately 5,500 humanoid units delivered in 2025.
A key element of Unitree's strategy is vertical integration of the robotics supply chain. The company designs and manufactures its own core components, including motors, reducers (gearboxes), controllers, and perception and motion control algorithms. This vertical integration allows Unitree to reduce costs dramatically compared to competitors who source individual components from specialized suppliers. By controlling the full stack from actuators to software, Unitree can optimize the interactions between hardware and software in ways that third-party component users cannot.
Unitree relies heavily on reinforcement learning (RL) for locomotion control. The company trains locomotion policies in simulation environments and then transfers them to physical robots through a process known as sim-to-real transfer. In December 2024, Unitree open-sourced portions of its RL training framework along with sim-to-sim and sim-to-real migration code, a move the company said could shorten R&D cycles by up to 30%.
The company maintains open-source repositories on GitHub supporting RL training for the Go2, H1, and G1 platforms. These repositories use physics simulators including MuJoCo and NVIDIA Isaac Sim. Researchers at various institutions have built on Unitree's platforms to develop advanced locomotion behaviors, including robust motion tracking under real-world disturbances with zero-shot sim-to-real transfer on the G1.
Unitree's robots use proprietary electric actuators rather than the hydraulic systems favored by some competitors. Electric actuation provides advantages in cost, weight, energy efficiency, and noise levels, though it traditionally offers less raw power than hydraulics. Unitree has pushed the boundaries of electric actuation performance, as demonstrated by the H1's 360 N·m knee torque and the B2's ability to leap over 1.6-meter obstacles. The G1's actuators deliver up to 120 N·m of joint torque in a compact, lightweight package.
Unitree has experienced rapid revenue growth, particularly as humanoid robots have entered its product lineup. According to the company's IPO filing with the Shanghai Stock Exchange in March 2026:
| Year | Revenue (RMB) | Notes |
|---|---|---|
| 2022 | 123 million yuan | Early commercial phase |
| 2023 | 159 million yuan | Quadruped-dominated revenue |
| 2024 | 392 million yuan | Humanoids 27.6% of main business revenue |
| 2025 | 1.71 billion yuan | 335% YoY growth; humanoids 51.5% of revenue (Jan-Sep) |
The company's gross margins have improved consistently, rising from 44.2% in 2023 to 56.4% in 2024 and 60.3% in 2025. Net income reached 105 million yuan in 2025 on an unadjusted basis, while adjusted net profit soared to approximately 600 million yuan, representing a 674% increase year-over-year. The company was unprofitable in 2022 and 2023 before turning profitable in 2024.
Domestic sales in China became the majority of revenue for the first time in 2025, with overseas markets contributing 39.2%.
Unitree has raised a total of approximately $155 million across multiple funding rounds. Notable investors include some of China's largest technology and investment firms:
The company's most recent funding round in June 2025 valued Unitree at 12.7 billion yuan (approximately $1.7 billion), making it a unicorn. Secondary market transactions reportedly valued shares at over 15 billion yuan in the first half of 2025.
On March 20, 2026, Unitree filed an IPO application with the Shanghai Stock Exchange's STAR Market, seeking to raise 4.2 billion yuan (approximately $610 million). The filing was formally accepted following a preliminary review. According to the prospectus, the proceeds will fund research into AI models for robotics, development of new products, and expansion of manufacturing facilities.
Between 2022 and September 2025, Unitree shipped over 30,000 quadruped robots and more than 4,000 humanoid robots. Total humanoid deliveries for the full year 2025 reached approximately 5,500 units, which Unitree claims represents a leading position in the global humanoid robot market.
The most frequently drawn comparison is between Unitree and Boston Dynamics, the American robotics company owned by Hyundai. Boston Dynamics' Spot quadruped robot sells for $74,500, while Unitree's Go2 starts at $1,600. This represents a price difference of over 95%. Over a three-year period, the total cost of ownership for a Go2 (including maintenance and parts) is estimated at approximately $5,000, compared to over $95,000 for a Spot (including the robot cost and three years of annual support at roughly $7,000 per year).
However, the two companies target different markets. Spot is designed for industrial inspection, construction sites, public safety, and enterprise deployment, with IP54-rated ruggedness, higher payload capacity, and certified autonomous navigation. The Go2 is primarily aimed at consumers, hobbyists, educators, and researchers who need an affordable platform for learning and experimentation. Unitree's industrial B2 model competes more directly with Spot, though at a higher price point than its consumer products.
Unitree operates within a rapidly growing Chinese humanoid robotics ecosystem. Other major Chinese competitors include:
Chinese companies collectively controlled approximately 90% of the global humanoid robot market in 2025 by shipment volume. Industry analysts consider AgiBot, Figure AI, Tesla (Optimus), UBTECH, and Unitree to be the first-tier players globally.
Beyond China, Unitree faces competition from several well-funded Western and international companies:
Unitree's central business thesis is that robotics will follow the trajectory of smartphones and personal computers: performance will improve while costs drop, eventually making robots accessible to ordinary consumers and small businesses. Wang Xingxing has stated publicly that his goal is to make robots as common as household appliances.
This strategy manifests in several ways:
The period from 2025 into early 2026 has been transformative for Unitree:
Wang Xingxing (born 1990, Ningbo, Zhejiang) is the founder and CEO of Unitree Robotics. A member of the post-1990s generation of Chinese entrepreneurs, Wang earned his bachelor's degree from Zhejiang Sci-Tech University before completing his master's in mechatronics engineering at Shanghai University. His XDog quadruped project, developed during his graduate studies, became the technical foundation for Unitree.
Wang briefly worked at DJI in 2016 before leaving to found Unitree. His approach to robotics has been compared to the strategies of consumer electronics companies: focusing on cost reduction and mass production rather than building the most capable (and most expensive) robots possible. Wang has been recognized as one of China's leading young technology entrepreneurs, and he attended a symposium with Chinese President Xi Jinping in 2025, reflecting the government's growing interest in humanoid robotics as a strategic industry.
As of early 2026, Unitree operates with a lean team. Reports indicate the company had approximately 61 employees as of late February 2026, though this figure may undercount contract and manufacturing staff.
Unitree's rise reflects several broader trends in robotics and technology:
