Joint Project by the Ministry of Land, Infrastructure and Transport & Ministry of Trade, Industry and Energy, South Korea (2025.04 ~ 2029.12)

Research Objectives

A construction robot platform will be developed to support three specialized high-altitude tasksโ€”welding, painting, and fireproof sprayingโ€”through XR-based remote human-robot collaboration and a multi-robot integrated operation system, improving safety and productivity on construction sites.

  • (Subtask 1 - MOLIT, KRW 17B) Development of Human-Robot Collaboration and Integrated Operating System for Construction Work at Height
  • (Subtask 2 - MOTIE, KRW 11B) Development of autonomous work at construction sites and multi-robot autonomous driving technology
