South Korea’s Diden Spider Robot Designed For Ship Inspection And Welding
Korean robot tackles difficult welding tasks inside ships.
A four-legged industrial robot known as the Diden Spider is attracting attention for its ability to climb steel walls, move across ceilings and perform tasks such as welding. Developed by South Korean company Diden Robotics, the robot is designed to work in environments where conventional machines can struggle to reach or operate effectively.
The quadruped robot uses magnetic feet to remain attached to steel surfaces as it moves across floors, vertical walls and ceilings. This allows it to operate in positions that would be difficult for standard wheeled or ground-based robots. Its design is particularly suited to shipyards, where large vessels contain narrow spaces, uneven surfaces and hard-to-reach sections.
The Diden Spider can carry loads of up to 30 kg and is capable of navigating complex structures and tight openings. Its platform can also be equipped with specialised tools for activities including welding and inspection. The combination of mobility and tool-carrying capacity is intended to make the robot useful for more than simple movement or monitoring.

One of the robot's key capabilities is remaining attached to steel surfaces while moving vertically or upside down. In shipbuilding environments, this could allow it to access sections of vessels that may otherwise require workers to use ladders, harnesses or other safety equipment. The technology is still under development, but its capabilities point to possible applications in tasks involving difficult or potentially hazardous access.
Diden Robotics says the Spider has been demonstrated in Korean shipyards, including during welding operations on vessels under construction. The robot has also undergone testing by Samsung Heavy Industries, providing an example of how the technology is being evaluated for industrial applications outside laboratory settings.
Beyond shipbuilding, the robot could potentially be adapted for inspection, maintenance and repair work on large steel structures. Its ability to move across surfaces that are inaccessible to conventional robots could allow it to perform certain tasks in locations where human access is difficult or carries additional safety challenges.
