About X Square

Independent Variable Robot Technology (also known as X Square Robot) is a developer of general-purpose embodied intelligent large models, established in December 2023 and headquartered in Ningbo, China, with additional research and operational centers in Beijing, Shanghai, and Shenzhen. The company focuses on creating general-purpose robots with fine manipulation capabilities, utilizing an end-to-end model that processes real-world data from perception to action. The core team includes researchers from globally recognized AI and robotics labs, one of the original proponents of the Attention mechanism (a core component of Transformer models), the algorithm leader for one of China's first trillion-parameter large models, and entrepreneurs from the robotics hardware sector.

The firm's primary offering is its self-developed "GreatWall" operation large model series, specifically the WALL-A model, which enables robots to perform tasks with high precision and autonomy in complex environments without relying on traditional rule-based programming. This technology is integrated into their proprietary robot platforms, the Quantum 1 (Quanta X2) and Quantum 2, which are designed for soft-hardware co-evolution. These robots feature a high degree of freedom, including a five-fingered dexterous hand, and are built to be adaptable for various applications. The Quantum 2 model stands 172cm tall, weighs 95kg, and has a single-arm payload capacity of 6kg.

Independent Variable Robot Technology serves clients across multiple sectors, including scientific research, education, logistics, and home services. The business model appears to involve both the sale of its robotic hardware platforms and potentially customized development services for enterprise clients, supported by a software development kit (SDK) compatible with Python/C++ for secondary development. The company has secured significant funding to accelerate its development, including a Series A round led by Meituan Strategic Investment and Meituan Longzhu, and a Pre-A++ round led by Lightspeed China Partners and Legend Capital.
