What is a quadruped robot?
A quadruped is a four-legged robot that walks, climbs or carries loads on rough ground — from warehouse dogs to magnetic shipyard Spiders.

Definition
A quadruped robot moves on four legs. Designs range from animal-inspired "robot dogs" to specialized climbers with magnetic or adhesive feet.
Why it matters
Uneven yards, stairs and vertical steel are hard for wheels. Quadrupeds fill that gap while humanoids chase general-purpose hands — and site-specific quadrupeds often reach paid work first.
Frequently asked questions
How is it different from a wheeled AMR?
Wheels need flatter floors. Legs step over debris, stairs and sometimes climb walls with magnets or grippers.
Where are quadrupeds used?
Inspection, security, construction, shipyards and research. Korea's Didin Spider is a magnetic shipyard example.
Are they the same as humanoids?
No. Quadrupeds trade human-like hands for stability and payload on uneven terrain.
Coverage
Korea's bet on site-tailored robots: construction haulers, wall-climbing Spiders and pipe inspectors
While humanoids grab headlines, Kore, Didin and Kalman are shipping task-specific machines into construction sites, shipyards and nuclear plants — with Oct 2026 deployments already lined up.
