Lanxin Robotics VB1-I — Specs, Price & Where to Buy (2026)

What is the Vb1 I Lanxin?

The Lanxin Robotics VB1-I, also known as the VB1-I Industrial variant, is a modular humanoid robot designed for embodied AI research and industrial testing. Developed by Lanxin Robotics in China, it features an aluminum alloy frame with composite covers, standing approximately 165 cm tall and weighing around 60 kg. The robot is equipped with high-torque electric servo motors and harmonic reducers for smooth motion. Its 5-fingered hands offer around 6–7 degrees of freedom each, contributing to an overall total of approximately 40–45 DOF. The VB1-I is built on an Industrial PC with AI accelerator and a Linux-based robotics OS, supporting Ethernet and Wi‑Fi connectivity. It is primarily targeted at research institutions and companies exploring advanced humanoid autonomy and physical AI testing. As of 2026, the VB1-I remains a pre‑commercial platform not sold to the public.

Price & Value

New MSRP: Undisclosed

Used range: N/A

The VB1-I is not yet commercially available; pricing is undisclosed and likely only available through direct partnership or leasing agreements. Given its research‑oriented positioning and modular design, any eventual price would compete with other Chinese humanoid platforms like the UBTECH Walker S or Fourier GR-2, which typically range between $100,000 and $200,000 depending on configuration. Until a public price list is released, total cost of ownership remains speculative, but maintenance, software licensing, and potential end‑effector modules could add significantly. For labs that need a ROS2‑native, modular humanoid now, Lanxin’s only option is to inquire directly. The lack of a used market means no depreciation data exists yet. As more units enter field trials, a clearer value proposition may emerge.

Who Is It For?

Best for: - University robotics labs seeking a modular humanoid platform for embodied AI and manipulation research - Industrial R&D teams testing humanoid‑based automation in controlled manufacturing environments

Not for: - Heavy‑duty industrial deployment (no published payload, battery life undisclosed, and unproven in real‑world factories) - Budget‑constrained projects (no pricing available, but likely high‑cost commercial‑grade)

Alternatives & Comparison

The VB1‑I competes in the growing field of Chinese humanoid research platforms, alongside established names like the UBTECH Walker S and Fourier GR‑2. While each platform emphasizes different strengths, they share a common target: advancing embodied AI in the lab and on the factory floor.

Verdict: For research groups that need a modular, ROS2‑native humanoid with a wide range of motion and simple integration, the Lanxin VB1‑I is a compelling platform if procurable. However, those seeking proven industrial robustness should consider the UBTECH Walker S, and labs focusing on dexterous manipulation will find the Fourier GR‑2’s hand capabilities more advanced. The VB1‑I’s advantage lies in its modularity and potential lower cost, but its immature support and lack of a public track record remain significant unknowns.

Use Cases & Capabilities

Embodied AI Research

The VB1‑I’s modular design and ROS2 compatibility make it ideal for developing and testing embodied AI algorithms. Researchers can swap end‑effectors and integrate external LLMs via its onboard Industrial PC. Its 40‑plus DOF allow for human‑like motion studies in navigation and object interaction, while Wi‑Fi and Ethernet connectivity simplify remote operation and data logging. The platform’s use of high‑torque servos and harmonic reducers provides the smooth, repeatable movements essential for machine learning model training. Because the robot is still a prototype, early adopters can influence its development, gaining a competitive edge in humanoid research.

Industrial Testing & Light Automation

With a reinforced joint design, the VB1‑I is intended for light factory tasks such as parts sorting, assembly, and inspection. Its 5‑fingered hands and stereo RGB vision enable it to pick and place objects with modest precision. While no official payload is given, its sibling VB2 handles up to 5 kg, suggesting the VB1‑I can manage similar small‑part loads. The robot’s Ethernet and Wi‑Fi connectivity allow integration with existing manufacturing execution systems (MES). However, its lack of a certified runtime and unknown battery endurance means it currently stays tethered or runs short trials, limiting its use in 24/7 industrial scenarios.

Academic Education and Student Projects

For university robotics labs, the VB1‑I provides an accessible full‑body humanoid that can be programmed in ROS2. Its modular structure allows students to modify end‑effectors or add sensors. The aluminum alloy frame is robust enough to survive daily use in a teaching environment. Lanxin’s relationship with research institutes suggests a possible academic licensing model, though no educational pricing is confirmed. Because the ecosystem is still nascent, students may face a steeper learning curve, but the platform offers hands‑on experience with cutting‑edge hardware comparable to far more expensive European humanoids.

History & Background

Lanxin Robotics, headquartered in China, emerged in the early 2020s as a developer of modular humanoid platforms for research and industry. The VB1 series was first introduced in 2024 with the launch of the VersaBot VB1 and the more rugged VB1‑I variant, the latter designed for heavier industrial tasks with reinforced joints. A second generation, the VB2, followed in 2025, featuring improved manipulation and an extended battery life of 4–6 hours. The company positions itself as an enabler of embodied AI, targeting universities and R&D centers that need a flexible, open‑source‑friendly humanoid. As of 2026, Lanxin has not publicly disclosed sales figures or price lists, indicating that the VB1‑I remains a pilot‑phase product offered through direct partnerships rather than retail channels.

Buying Used — What to Check

Confirm actual DOF count The ~40–45 DOF figure is unverified; ensure the exact specification with all joints active.

Inspect joint wear High-torque servos and harmonic reducers can degrade over time; request maintenance logs.

Validate battery life Battery data is absent for VB1-I; if a third‑party pack is used, confirm capacity and runtime.
