What X Square does

X Square Robot (自变量机器人 / Zìbiànliàng Robot) is a Shenzhen-headquartered embodied-AI company founded in December 2023 that develops self-developed general-purpose embodied intelligence foundation models and the full-stack robot hardware that runs them. The company is among the earliest in China to adopt a fully end-to-end approach to general embodied intelligence, anchored by the proprietary "GreatWall" (WALL) series: WALL-A is a hundreds-of-billions-parameter Vision-Language-Action foundation model enabling autonomous perception, decision-making and high-precision manipulation; WALL-B is a next-generation World Unified Model jointly training vision, language, action and physical prediction; and WALL-OSS-0.5 plus WALL-WM are open-source VLA and World Action Model releases that post state-of-the-art benchmarks (WALL-OSS-0.5 outperforms π0.5 by 17.5pp; WALL-WM ranks #1 on Real-Robot Core15 at 58.3). The XRZero-G0 hardware-software framework for robot-free data collection, with the 2,000-hour G0-Dataset, completes the proprietary AI stack.

The company pairs its foundation models with fully in-house robot hardware: the Quanta X1 (97cm, 20-DOF wheeled dual-arm research robot), the Quanta X2 (164cm, 62-DOF wheeled humanoid with ±0.03mm repeatability, 6kg/25kg payload) and the ArtiXon Hand (20-DOF, 15-active-drive five-finger dexterous hand with fingertip tactile sensors). Go-to-market combines direct enterprise sales of hardware to research institutions and industrial customers, robot-as-a-service home cleaning through a partnership with 58.com / 58 Daojia (149 yuan per 3-hour session, ~200 households booked in Shenzhen and Beijing since March 2025/2026), a joint venture with Holike for home renovation customers, an OEM/embedded channel through D-Robotics' Xuri S600 edge-AI platform (distributed by Hong Kong-listed Ingdan), and a government-aligned ecosystem partnership with Hefei. Open-source releases, the BRIGHT 2026 hackathon, the EAIDC 2026 developers conference, and the CVPR 2026 ManipArena benchmark build a global developer ecosystem on top of the proprietary stack.

X Square is privately held and has completed roughly ten funding rounds in approximately 2.5 years, raising a cumulative ~$590M+ including a ~RMB 2 billion (~$293M) Series B in April 2026 co-led by Xiaomi and HongShan with Meituan, Alibaba and ByteDance. This makes X Square the only Chinese embodied-intelligence company backed by all four major Chinese tech ecosystems. The company employs 101-250 people across R&D and operations centers in Beijing, Shanghai, Shenzhen and Hefei, is led by founder and CEO Wang Qian (王潜) and CTO Wang Hao (王昊), and was named to the Forbes China 2026 AI Tech Enterprises Top 50.

Core offering

X Square develops and sells full-stack embodied AI and humanoid robotics: self-developed GreatWall-series foundation models (WALL-A 100B+ VLA, WALL-B World Unified Model, open-source WALL-OSS and WALL-WM) combined with proprietary robot hardware including the Quanta X1 and Quanta X2 wheeled dual-arm humanoid robots and the ArtiXon Hand 20-DOF dexterous hand. The company also delivers a consumer-facing robot-as-a-service home cleaning offering via its 58.com partnership and open-sources developer tooling (XRZero-G0) plus foundation model weights on GitHub and Hugging Face.

Product overview

X Square Robot (自变量机器人) sells a vertically integrated embodied-AI platform rather than a single product. The center of the platform is the self-developed WALL-A GreatWall operation large model, a hundreds-of-billions-parameter end-to-end embodied foundation model, now joined by the next-generation WALL-B (World Unified Model) and the open-source WALL-OSS / Wall-OSS-0.5 VLA model family as well as the WALL-WM World Action Model. These models run on the company's full-stack robot hardware: the Quanta X1 wheeled dual-arm research robot, the Quanta X2 next-generation wheeled humanoid, and the ArtiXon Hand high-DOF five-finger dexterous hand as the end-effector. The company also publishes open-source tooling, including the XRZero-G0 hardware-software framework for robot-free data collection together with the 2,000-hour G0-Dataset, and operates the BRIGHT 2026 global embodied intelligence hackathon and the EAIDC 2026 developers conference to seed an external ecosystem around its open-source models.

• Galbot (银河通用): Beijing-based embodied-AI humanoid startup founded 2023, also pursuing a foundation-model + hardware approach with G1 wheeled humanoid and large-scale data flywheel. Closely comparable stage, technology stack and target verticals (industrial, retail, home) to X Square.

Emerging players

• Physical Intelligence: San Francisco-based pioneer of the π0/π0.5 VLA foundation models against which X Square benchmarks WALL-OSS-0.5. Software-only model that supplies policies to multiple humanoid OEMs, a model X Square is partially mimicking with its own OEM-licensing push via D-Robotics.
• 1X Technologies: Norway/US humanoid robotics company (Neo) backed by OpenAI and EQT, focused on home service robots. Closest international peer to X Square's home-cleaning robot service concept and WALL-B-powered consumer use case.

Broad incumbents

• Figure AI: US-based humanoid robotics company (Figure 02) targeting industrial deployments with BMW and others. Backed by Microsoft, OpenAI, NVIDIA, Intel. Comparable general-purpose humanoid product positioning and foundation-model investment trajectory, with deeper manufacturing-scale capital.
• Apptronik: Austin-based humanoid robotics company (Apollo) with Google DeepMind partnership for embodied AI. Targets logistics and manufacturing; closely comparable wheeled humanoid product category to X Square's Quanta line.

Others

• D-Robotics (地平线 / 瑞芯微? actually D-Robotics is a robotics compute platform partner): Edge-AI computing platform provider whose Xuri S600 chip hosts X Square's WALL-B model. Listed as a strategic partner in this dataset; treated here as an ecosystem/OEM enabler rather than a direct competitor, comparable to how NVIDIA Jetson enables the broader embodied-AI category.
