About UBTECH Robotics
UBTECH Robotics Corp Ltd (深圳市優必選科技股份有限公司) was formally registered in Shenzhen, Guangdong on 31 March 2012 by founder Zhou Jian — who uses the English name James Zhou — with roughly RMB 10 million in registered capital. Zhou, sometimes described in Chinese media as the "father of robots" in China, famously sold shares in earlier ventures and mortgaged his home to fund the company's foundational research into digital servo actuators, the small, precise motors that sit at every joint of a modern humanoid robot. That servo work — with development dating back to roughly 2008 — remains the technical core that everything else in the company is built on.
UBTECH's public trajectory over the last decade has been unusual for the sector: it built a real business in consumer, education, and service robotics before the current humanoid AI boom, which gave it operating cash flow and manufacturing depth that most humanoid startups still lack. Its first commercial humanoid, the small consumer robot Alpha, arrived in 2014; in 2016, 540 Alpha units performed together on CCTV's Spring Festival Gala, a moment that made the brand a household name in China. The company then expanded into commercial service robotics with Cruzr, into STEM kits with Jimu, and finally into full-size bipedal humanoids with the Walker research platform (2018) and the industrial Walker X, Walker S, Walker S1, and 2025 flagship Walker S2.
On 29 December 2023, UBTECH listed on the Main Board of the Hong Kong Stock Exchange under ticker 9880.HK, becoming the first humanoid-robotics company to list on a stock-exchange main board anywhere in the world. The IPO priced at HK$90 per share — the low end of its indicative range — raising more than HK$1 billion (approximately US$128–130 million) for a listing-day market capitalisation of roughly HK$37.6 billion (about US$4.8 billion). A Walker S humanoid struck the opening gong alongside Zhou Jian, the first time in the exchange's 132-year history that a robot rang the bell. UBTECH's FY2025 results reported revenue of roughly ¥2.0 billion (up 53%) with the humanoid segment growing more than 2,000% year over year to become the company's largest business.
UBTECH's competitive set today includes both other Chinese full-size humanoid makers — Unitree, XPeng Iron, and Agibot — and the leading Western general-purpose robotics companies including Figure AI, Tesla Optimus, 1X, Apptronik, and Boston Dynamics. UBTECH's distinguishing bet is industrial commercialisation: rather than showcase demo videos, it has pushed Walker S-class robots onto real automotive assembly lines at BYD, Geely, and FAW-Volkswagen, and moved Walker S2 into genuine mass production out of its Liuzhou plant in late 2025.
Product lineup: Walker, Cruzr, Alpha, and Jimu
UBTECH sells across four product families: the full-size industrial Walker humanoids that anchor the company's current growth, the Cruzr service robot for retail and reception, the small consumer humanoid Alpha, and the Jimu STEM construction kits used in K-12 robotics education. The Walker line is the one that matters most to the company's public narrative and its FY2025 humanoid revenue surge.
Walker & Walker X (2018–2021) — the research and commercial platform
The original Walker, unveiled in 2018, was China's first commercialised bipedal life-sized humanoid robot. It was followed by Walker X (2021), a redesigned platform used for demonstrations, exhibitions, and early enterprise pilots — including reception, guiding, and light service tasks. Walker X established the mechanical and control baseline that the industrial Walker S series would later build on.
Walker S & Walker S1 (2024) — the industrial pilots
Walker S was UBTECH's first Walker positioned explicitly as an industrial humanoid, with a more human-like configuration, higher-torque actuators, and a control stack tuned for factory tasks. Walker S1 extended that work and served as the platform for the company's first widely publicised automotive assembly-line trials at Chinese automakers, including collaborative multi-robot demonstrations at BYD.
Walker S2 (2025) — the mass-production flagship
Walker S2 is UBTECH's most significant product step to date. Unveiled 17 July 2025 and moved into mass production on 17 November 2025 at the Liuzhou plant, Walker S2 is the world's first humanoid robot capable of autonomous battery swapping — the robot senses low charge, walks to a swap station, and exchanges its own battery pack in roughly three minutes without any human intervention, enabling continuous multi-shift operation. It is also the first industrial humanoid integrated with UBTECH's proprietary Co-Agent intelligent-agent system for closed-loop intention understanding, task planning, tool use, and autonomous anomaly handling. UBTECH shipped 1,079 full-size humanoid units cumulatively in 2025 and holds an order book placed near ¥1.4 billion by December filings, with capacity scaling toward 5,000 units in 2026 and 10,000 in 2027.

Technology stack
UBTECH's platform is a vertically integrated combination of in-house servo actuators, sensor fusion, onboard compute, and — with Walker S2 — the proprietary Co-Agent intelligent-agent system layered over the company's BrainNet 2.0 AI architecture. UBTECH's edge traces back to a decade of internal work on the mechatronic building blocks (servos, gearboxes, controllers) that most other humanoid startups still buy from external suppliers.
Perception
Walker S-series robots use dual RGB stereo cameras for full situational awareness, supplemented by time-of-flight depth sensing, IMUs for whole-body balance and gait control, and six-axis force-torque sensing at the wrists for contact-rich manipulation. This mix of vision, depth, inertial, and tactile signals is what allows Walker S2 to perform assembly-line tasks like inserting parts, gripping deformable objects, and reacting to unexpected contact in unstructured factory environments.
Co-Agent, BrainNet 2.0, and whole-body control
Co-Agent, unveiled with Walker S2, is UBTECH's proprietary intelligent-agent system providing closed-loop intention understanding, task planning, tool usage, and autonomous anomaly detection and handling. It sits on top of the company's BrainNet 2.0 AI architecture, which coordinates the robot's multiple neural components and drives real-time whole-body control. Because Co-Agent runs on the robot itself, Walker S2 does not require cloud connectivity for real-time factory tasks.
Actuators, power, and compute
UBTECH uses electric brushless DC (BLDC) servo actuators throughout the body — no hydraulics — with the actuator modules, gearboxes, and drive electronics developed in-house from the company's original servo research. Walker S2 has 52 degrees of freedom overall (22 in the hands), a top speed of 7.2 km/h, and a 15 kg payload rated up to a 1.8 m workspace. The onboard compute stack runs the Co-Agent and BrainNet 2.0 models locally, and the battery pack is engineered specifically for the industrial autonomous-swap workflow that gives Walker S2 its multi-shift uptime.
Power management is a particularly demanding subsystem for a humanoid of this class. Each joint's servo controller must deliver hundreds of watts of instantaneous torque without thermally throttling, which drives the use of high-efficiency wide-bandgap semiconductors — SiC and GaN — in the motor-driver stages and requires tightly matched precision passives on every gate-drive and current-sense channel. The onboard battery pack integrates cell balancing, thermal management, and multi-stage protection ICs, along with the MLCC capacitors and precision resistors that condition every power and signal rail — subsystems whose reliability is often the practical ceiling on how long an industrial humanoid platform can run between battery swaps.
Applications and commercial deployments
UBTECH's stated market is industrial commercialisation — factory work, logistics, and, more recently, high-security public-safety deployments. The company has been unusually specific about naming customer sites, and by late 2025 was reporting hundreds of Walker S2 units in live operation across multiple industrial scenarios.
- BYD. Walker S1 and Walker S2 robots have been trialed on BYD's electric-vehicle assembly lines, including collaborative multi-robot demonstrations of vehicle-body handling and quality-inspection tasks.
- Geely (Zeekr). UBTECH ran Walker S trials at Geely's Zeekr smart factory, part of a broader wave of Chinese automotive assembly-line humanoid pilots throughout 2024 and 2025.
- FAW-Volkswagen. Walker S has been evaluated at FAW-Volkswagen production sites, one of several joint-venture automaker pilots that helped establish Walker as a serious industrial platform rather than a demo robot.
- Airbus (January 2026). Walker S2 units entered aviation manufacturing pilots at Airbus, extending UBTECH's industrial footprint beyond automotive.
- Additional deployments. UBTECH has publicly disclosed Walker S2 use in logistics and border-security scenarios, alongside a Walker S2 order book that December 2025 filings placed near ¥1.4 billion, with capacity guidance of 5,000 units in 2026 and 10,000 in 2027.
The robotics supply chain — where Hybrid Electronics fits in
A modern humanoid robot is one of the most component-dense products ever built. A single Walker S-class platform depends on thousands of individual electronic components: precision BLDC motor drivers, high-torque servo modules, IMUs and 6-DoF force-torque sensors, LiDAR and time-of-flight modules, GPU compute boards, battery-management ICs, wide-bandgap SiC/GaN power semiconductors, high-speed board-to-board connectors, precision resistors, and thousands of MLCC capacitors distributed across every power and signal rail.
Building that kind of hardware puts enormous pressure on the electronic-components supply chain. Prototype pilots and low-volume production runs frequently hit allocation, EOL notices, and long lead times on the exact parts they need, and R&D and field teams routinely have to support older platforms that use semiconductors no longer in mainstream distribution. During the current humanoid robotics and general-purpose robot AI boom, this pressure is amplified: dozens of well-funded teams are chasing the same short list of high-torque BLDC drivers, precision IMUs, GPU compute modules, and automotive-grade power semiconductors, and franchise stock on many key parts is now measured in months of lead time rather than weeks.
Hybrid Electronics has been sourcing electronic components for industrial and embedded systems since 1995. For robotics teams — humanoid, mobile, industrial, and research — we specialize in finding the parts you need when mainstream distribution can't:
Obsolete and end-of-life parts
Legacy semiconductors, sensors, connectors, and passives that are no longer in mainstream distribution — the parts that keep older platforms running during transitions to newer hardware, and the long-tail items that block a BOM from closing.
Allocated and hard-to-find active parts
High-torque BLDC motor drivers, IMUs and MEMS sensors, SiC/GaN power devices, GPU compute modules, precision resistors, and MLCC capacitors caught in allocation or long-lead times. Send us a BOM or a shortage list — we'll confirm what we can source and at what lead time.
