X Square Robot (Chinese: 自变量机器人; pinyin: Zìbiànliàng Jīqìrén) is a robotics and artificial intelligence company headquartered in Shenzhen, China. Founded in December 2023 by Wang Qian, the company develops embodied AI foundation models and robot hardware.[1][2][3] Its products include the WALL series of embodied AI models, the QUANTA series of robots, the ArtiXon dexterous hand, and the QUANXTA Zero data-collection platform.[2][4]

History

X Square Robot was founded in December 2023 in Shenzhen.[1][5][3] In September 2025, the company raised nearly 1 billion yuan (about US$140 million) in a Series A+ round led by Alibaba Cloud, the first investment by Alibaba's cloud unit in embodied intelligence. Other participants included HongShan, Meituan and Legend Capital.[6][7][8] Alongside the round, the company released WALL-OSS, an open-source embodied foundation model, and the QUANTA X2 wheeled humanoid robot.[4][7][9]

In January 2026, X Square Robot completed a 1 billion yuan (about US$140 million) A++ round led by ByteDance, HongShan and Shenzhen Capital Group, alongside other funds.[1][10][11][12]

Between late March and early April 2026, the company closed a Series B round of nearly 2 billion yuan (about US$276 million), led by Xiaomi's strategic investment arm and HongShan.[5][13][14]

In March 2026, X Square Robot co-organised the Embodied AI Developers Conference (EAIDC 2026) and an accompanying hackathon in Nanshan District, Shenzhen. More than 100 teams took part, with 20 reaching the final.[15][16]

In June 2026, the company announced it had closed four consecutive financing rounds culminating in a Series C, bringing its valuation to more than US$2.8 billion (about 20 billion yuan). IDG participated in the Series C round. Combined with earlier lead investments from Meituan, Alibaba, ByteDance and Xiaomi, X Square Robot has become the only embodied AI company in China to secure lead-round backing at different stages from four of the country's leading technology companies.[17][18][19][20]

Technology and products

WALL models

The WALL series is a family of embodied AI foundation models.[2] WALL-OSS, released in September 2025, is an open-source vision-language-action model distributed with model parameters, training and inference code, and toolchains.[4][7][8][21]

In April 2026, the company introduced WALL-B, a foundation model built on its World Unified Model architecture, which trains perception, language, action and physical prediction within a single network rather than as separate modules.[2][17][22][14] The model was unveiled at an event in Beijing.[23]

The company has also open-sourced WALL-OSS-0.5 and WALL-WM, extending its unified approach to robot manipulation and world modeling.[2][17]

Data collection

In 2026, X Square Robot introduced the QUANXTA Zero Series, a hardware and software platform for embodiment-free embodied data production. The family comprises the Zero G1, which uses a headband and dual grippers to capture movement, visual, tactile and audio data; the Zero G0, which supports whole-body mobile collection using a VR headset, dual grippers and a backpack; and the compact Zero E0, equipped with six cameras.[2]

In June 2026, the company open-sourced XRZero-G0 together with the G0-Dataset, a 2,000-hour multimodal dataset for robotics research.[24]

Robots

The company's hardware includes the QUANTA X1 Pro, a wheeled bimanual robot used as a research platform, and the QUANTA X2, a wheeled humanoid robot for service, household and industrial use. The QUANTA X2 has a wheeled chassis, arms with seven degrees of freedom and 20-degree-of-freedom dexterous hands, with up to 62 degrees of freedom in total.[4][2]

Deployments

X Square Robot has tested its robotic systems in household, logistics, manufacturing, hospitality and public-service environments. In March 2026, X Square Robot partnered with the Chinese household-services platform 58.com to launch a cleaning service in Shenzhen in which a wheeled robot works alongside a human cleaner.[25][26][23] The service was later extended to Beijing.[2][17]

The company also runs the "X Family Member Program", under which robots are placed with households for periods of up to one month.[17][2] The company is also working with one of China’s leading logistics companies to introduce embodied AI robots into parcel feeding and sorting operations.[2]
