Chinese robotics company Agibot (智元机器人) has introduced the X2-N, a humanoid robot designed with a unique dual-mode locomotion system that allows it to switch between bipedal and wheeled forms. This innovative feature aims to enhance the robot’s versatility and ability to navigate complex and varied environments.

In bipedal mode, the X2-N can climb stairs while carrying loads of up to 12 pounds. In wheeled mode, it can handle obstacles such as single-sided bridges and ramps.

The dual-mode functionality reflects advancements in robotics that aim to enhance adaptability across different environments. Potential applications for the X2-N include logistics, healthcare, and public services.

Agibot, a Shanghai-based startup established in February 2023 by former Huawei engineer Peng Zhihui, has rapidly gained traction in the robotics sector. The company’s focus is on developing AI-powered humanoid robots for diverse applications.

🧠 Food for thought

1️⃣ Hybrid mobility represents a pragmatic evolution in robotics design

The Lingxi X2-N’s dual-mode capability addresses a fundamental challenge in robotics, the tradeoff between stability and terrain adaptability.

Wheeled robots, which dominate commercial applications, offer superior energy efficiency and stability but struggle with stairs and uneven terrain, while bipedal designs excel at complex environments but face stability and power consumption challenges 1.

This hybrid approach isn’t entirely new but represents a maturing solution to longstanding mobility limitations, with recent research like the DIABLO project similarly combining wheeled and bipedal elements to achieve versatile movement across varied surfaces 2.

Engineers have increasingly recognized that different mobility modes serve different purposes, wheels for efficiency on flat surfaces and legs for complex terrain, leading to this convergence in design philosophy that emphasizes adaptability over specialized configurations.

The approach potentially addresses concerns raised by critics of pure bipedal designs who point to their impracticality in commercial settings due to stability issues and energy inefficiency.

2️⃣ Chinese robotics companies rapidly scaling humanoid robot development

Zhiyuan’s introduction of the Lingxi X2-N follows a broader pattern of aggressive expansion in China’s robotics sector, with the company having already launched five humanoid models and achieved a valuation of 7 billion yuan (approximately $1 billion) shortly after establishment 3.

The company has built its own factory in Shanghai rather than relying on OEM assembly, an unusual move for startups that signals confidence in commercial demand 4.

This development is part of a larger competitive ecosystem in China, where companies like Unitree Robotics and Deep Robotics are similarly accelerating development of advanced humanoid and service robots with specialized capabilities 5.
