X Square Robot is a Chinese robotics company based in [[Shenzhen]], [[China]], focused on general-purpose embodied intelligence and full-size [[humanoid robot]]s. Founded in December 2023, the company develops humanoid robots and embodied AI foundation models for service, household, and industrial applications. X Square Robot's flagship products include the [[QUANTA X2]] wheeled humanoid robot and the WALL-OSS open-source foundation model. The company has attracted significant investment, including a $100 million funding round led by [[Alibaba Cloud]].
X Square Robot was founded in December 2023 in Shenzhen, China, with a focus on developing both humanoid robot hardware and the AI foundation models needed to control them. The company's approach of building a "full stack" of hardware and software differentiated it from companies that focused on either hardware or software alone.[1]
In October 2024, X Square Robot trained WALL-A, an early version of its foundation model. Demonstrations showed robots performing a diverse range of tasks, including hanging laundry, preparing shaved ice, winding cables around pegs, and sorting parcels of arbitrary shape, all controlled by a single model without task-specific reprogramming.[2]
In August 2025, X Square Robot released the [[QUANTA X2]], a fully in-house developed wheeled dual-arm humanoid robot. Remarkably, the company independently developed a complete technology stack in less than six months, including the robot hardware, high-degree-of-freedom dexterous hands, and exoskeleton teleoperation and data acquisition equipment.[3]
In September 2025, X Square Robot announced it had secured approximately $100 million in a funding round led by [[Alibaba Cloud]], marking Alibaba's first investment in the embodied AI sector. This was the startup's eighth round of financing since its founding less than two years earlier.[1]
In a follow-up round, X Square Robot completed nearly 1 billion yuan in Series A+ funding, again led by Alibaba Cloud, to fuel the company's full-stack development from foundational models to hardware.[4]
The [[QUANTA X2]] is X Square Robot's flagship humanoid robot.
| Specification | Details |
|---|---|
| Height | 172 cm |
| Weight | 95 kg |
| Total DOF | 62 |
| Arm DOF | 7 per arm |
| Hand DOF | 20 per hand (dexterous) |
| Chassis | 6-DOF omnidirectional |
| Top Speed | ~3.6 km/h |
| Payload | ~6 kg per arm |
| Runtime | ~2 hours per charge |
The QUANTA X2 combines embodied AI with a robust mechanical design to enable applications across service, household, and industrial environments. The robot features a wheeled chassis for stable indoor navigation and dual arms, each equipped with a 20-DOF dexterous hand capable of fine manipulation tasks.[5]
Demonstrated capabilities include 360-degree cleaning with attached mop heads, subtle pressure sensing in the hands, and general-purpose object manipulation.
X Square Robot developed WALL-OSS, a proprietary open-source foundation model for robotic platforms.
| Model Version | Key Capabilities |
|---|---|
| WALL-A (Oct 2024) | Multi-task manipulation: laundry, food prep, cable winding, parcel sorting |
| WALL-OSS | Open-source release for broader community use |
The WALL model family enables robots to perform diverse tasks from a single model without task-specific programming. This "generalist" approach to robot control represents a significant departure from traditional robotics, where each task requires dedicated programming.[2]
X Square Robot's technology encompasses several key areas:
X Square Robot began generating revenue from commercial sales before its major funding rounds. The company's robots are deployed in:
The company plans to expand internationally to markets including [[Japan]] and [[Singapore]].[1]
| Round | Amount | Lead Investor | Date |
|---|---|---|---|
| Series A | ~$100 million | Alibaba Cloud | September 2025 |
| Series A+ | ~1 billion yuan | Alibaba Cloud | 2025 |
X Square Robot completed eight funding rounds in less than two years since its December 2023 founding, reflecting strong investor interest in the embodied AI sector.[1]
