At a testing site of LE Robotics Co., Ltd. (hereinafter referred to as “LE Robotics”) in Chengdu, an engineer issues a command, and a quadruped robot equipped with a welding torch, cutting torch, and vision system immediately gets to work.
It can enter confined passages, multi-level platforms, and other complex environments to carry out welding operations—areas that conventional wheeled equipment often struggles to access or navigate safely.
This is the LE Robotics AI Welding Dog. In November, the product will depart from Pengzhou, Sichuan, for its debut at METALEX in Bangkok, Thailand, one of Southeast Asia’s major exhibitions for machine tools and metalworking.
Developing the AI Welding Dog to Address Industry Challenges
“This is an opportunity for exhibition and industry exchange. The LE Robotics AI Welding Dog is currently a concept prototype in the preliminary technology research and development stage. After the exhibition, the prototype will be returned to China for further development.
Our purpose in participating is to show international customers the direction of our technology: using Physical AI to take welding and cutting capabilities beyond fixed workstations and into unstructured industrial environments,” said Hu Haojie, CEO and Executive President of LE Robotics.
The LE Robotics AI Welding Dog is designed for unstructured industrial environments that conventional robots often struggle to access, including large-scale steel structure fabrication sites, ship sections, pipe racks, and multi-level platforms.
These environments present significant challenges: workpieces are large, structures are complex, and conventional equipment may be unable to reach or maintain stable positioning. As a result, many welding and cutting operations still rely on manual labor. Working at heights, in high-temperature conditions, and in environments filled with fumes and dust places significant physical demands on workers and exposes them to considerable safety risks.
“Our goal as an industrial embodied AI company is to keep welding workers away from hazardous environments and ensure weld integrity for a hundred years,” said Hu Haojie.

Fixed workstations have their limitations, and wheeled mobile robots also face limitations in accessibility. Steps, narrow passages, and multi-level platforms are places that wheels cannot easily reach. LE Robotics aims to use legs to overcome these barriers.
When the workpiece cannot be brought to the robot, LE Robotics is exploring ways to bring welding and cutting capabilities directly to the workpiece.
“The biggest challenge is whether the LE Robotics AI Welding Dog can maintain stable footing, achieve accurate visual perception, and perform precise welding and cutting once it reaches the work site,” Hu Haojie explained. “Every time it moves to a new position, it needs to re-localize. Any disturbances during operation must also be compensated for in real time.”

Building a Collaborative “Hand–Eye–Leg–Brain” System
The LE Robotics AI Welding Dog features an integrated “Hand–Eye–Leg–Brain” collaborative system.
Brain: The LE AI welding and cutting system, responsible for planning and decision-making.
Eye: SLAM-based autonomous navigation and 3D vision, enabling the robot to perceive its surroundings and identify weld seams and cutting paths.
Legs: The quadruped mobile platform, responsible for mobility and maintaining stable footing.
Hand: The robotic arm, welding torch, and cutting torch, responsible for carrying out welding and cutting operations.
Together, these components form a complete closed-loop system of Perception – Decision-Making – Execution.
We are not reinventing the legs. The quadruped robot platform is based on a product developed using a mature, commercially available platform,” Hu Haojie emphasized.
“The core of the AI Welding Dog lies in its industrial welding and cutting system capabilities. It shares the same underlying Physical AI technology platform as LE Robotics’ mass-produced mobile welding and cutting robots.
The confidence behind this vision comes from products that are already proven in real-world production.
As of June 2026, LE Robotics has established four major product lines, with more than 30 product models across its portfolio. Its business spans over 30 countries and regions, serving more than 100 Fortune Global 500 companies, with a customer repurchase rate of over 95%.
The strategic direction is clear: wheeled robots deliver today; legged robots explore tomorrow.
“These mass-produced products address our customers’ real needs today and provide the foundation for our exploration of future technologies,” said Hu Haojie.
LE Robotics continues to advance the development of core algorithms for industrial embodied intelligence, extending its capabilities into new robotic forms, including legged robots.
One Physical AI platform. Multiple forms of embodied intelligence.
From a broader perspective, industrial welding and cutting robots involve an entire industrial value chain, bringing together mechanical engineering, electrical systems, visual perception, software algorithms, welding and cutting equipment, process expertise, and engineering services. Each element is closely interconnected.
Although the LE Robotics AI Welding Dog is still in the preliminary technology research and development stage, the continued growth of the business makes multidisciplinary talent increasingly important.

“We will focus on further developing the ‘Hand–Eye–Leg–Brain’ collaborative system and accelerating the deployment of AI algorithms and 3D vision in high-end industrial applications. At the same time, we will expand into domestic and international markets and build localized delivery and service networks.
In addition, we will step up talent recruitment and strengthen our end-to-end capabilities, from research and development to engineering implementation,” said Hu Haojie.
“We hope to see more R&D, manufacturing, and engineering capabilities take root and grow in Pengzhou, while creating more opportunities for young people to develop their careers here.”
Rooted in Pengzhou, Growing Together with the City
The development of industrial robots cannot take place solely in laboratories. It must be closely integrated with manufacturing, testing, and real-world industrial applications.
“We value Pengzhou’s industrial capacity and manufacturing support infrastructure. The area has an established industrial foundation, including the petrochemical sector, while nearby Chengdu offers abundant talent and innovation resources,” said Hu Haojie.
By bringing R&D, manufacturing, testing, engineering implementation, and delivery together within a relatively concentrated region, companies can accelerate feedback and product iteration. This is particularly important for robotics companies.
This collaboration is reflected in more concrete ways in Pengzhou today.
Pengzhou is firmly committed to strengthening its manufacturing sector and developing a modern industrial system known as the “3311” Industrial Framework. The manufacturing sector’s share of GDP has ranked first among all districts and county-level cities in Chengdu for three consecutive years.
Meanwhile, Pengzhou is developing new quality productive forces based on local conditions, with a focus on specialized sectors such as industrial robotics and service robotics, while creating multiple benchmark applications of “AI + Manufacturing.”
LE Robotics’ intelligent welding application is a representative example of how Pengzhou is continuously advancing and upgrading intelligent manufacturing through real-world industrial applications.
LE Robotics has consistently focused on the development of AI-driven intelligent industrial welding and cutting robots.
Looking ahead, our robots will be designed to understand tasks, perceive their surroundings, and make decisions. They will move beyond fixed workstations and operate in a wider range of real-world industrial environments.
Our goal is to deepen our technological capabilities and bring practical robotic solutions directly into our customers’ production environments.
