Multipurpose Robotic Platform and XR-Based Human-Robot Collaboration for Work at Height in Construction
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 tasksโwelding, painting, and fireproof sprayingโthrough 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
