Leg-Arm Coordinated Operation for Curtain Wall Installation

Abstract

With the acceleration of urbanization, the number of high-rise buildings and large public facilities is increasing, making curtain walls an essential component of modern architecture with widespread applications. Traditional curtain wall installation methods face challenges such as variable on-site terrain, high labor intensity, low construction efficiency, and significant safety risks. Large panels often require multiple workers to complete installation. To address these issues, based on a hexapod curtain wall installation robot, we design a hierarchical optimization-based whole-body control framework for coordinated arm-leg planning tailored to three key tasks: wall installation, ceiling installation, and floor laying. This framework integrates the motion of the hexapod legs with the operation of the folding arm and the serial-parallel manipulator. We conduct experiments on the hexapod curtain wall installation robot to validate the proposed control method, demonstrating its capability in performing curtain wall installation tasks. Our results confirm the effectiveness of the hierarchical optimization-based arm-leg coordination framework for the hexapod robot, laying the foundation for its further application in complex construction site environments.
