DIDEN Spider, DIDEN Walker, DIDEN Humanoid

DIDEN Robotics builds Industrial Physical AI — a deployable robot platform engineered for the world's hardest manufacturing environments, starting with shipyards. We design and manufacture three legged-robot products that all run on a single in-house technology stack. Spider is an EPM (electro-permanent magnet) magnetic-foot quadruped that climbs vertical steel walls, traverses access holes as small as 60 cm, and carries up to 30 kg of manipulator payload at 90° vertical orientation. Spider is already in live deployment with Korea's Big-3 shipyards: Samsung Heavy Industries, Hanwha Ocean, and HD Hyundai. Target unit price: $70K. Walker is a magnetic-foot biped with an integrated manipulator, designed to fit through narrow access holes and reach confined spaces a quadruped form factor cannot enter. Walker is in prototype testing for Q2 2026 deployment. Humanoid is a 50 kg upper-body, 14-DOF dual-arm system targeted at $110K, capable of 30 kg dual-arm payload and complex manipulation across all four critical industrial task categories: welding, painting, inspection, and valve operation. All three robots share the same in-house stack: custom EPM magnetic-foot grippers, hollow-shaft actuators that reach 194 Nm/kg peak torque density (best-in-class versus Tesla, Unitree, CubeMars and Steadywin), an MPC + reinforcement-learning hybrid locomotion controller, 200 Hz Lie-group state estimation, Vision AI and SLAM for autonomous waypoint navigation, and a closed-loop Sim-to-Real data pipeline. DIDEN Robotics has 28 engineers, 11 from KAIST Hubo Lab — Korea's flagship humanoid robotics program. The company has $5M+ cumulative funding, $4M+ in direct government grants embedded within $13M+ multi-partner programs, and was featured in the opening of the NVIDIA GTC 2026 keynote. Our mission is to build the operating system for industrial Physical AI — robots that go where humans cannot safely go, performing the welding, painting, inspection, and valve work that today drives the world's most dangerous occupational injury rates.

DIDEN Robotics is a Physical AI company that builds robots for real industrial environments. Founded in March 2024 by four alumni of KAIST's Humanoid Robot Research Center, we develop everything in-house — from actuators, electrical systems, and mechanical structures to locomotion control, vision AI, and sim-to-real transfer.
