The mobile cable robot system can perform contact-based façade inspections. The robot consists of four components: 1) one or more mobile carriers with the cable-driven robot winches; 2) cable-driven robot to move the inspection end-tool; 3) the end-effector platform with inspection tools and stabilization; and 4) digital recording and data analysis of the building health. In terms of application, the system can conduct robotic inspections through automatic, precise inspection sensors. It also generates intuitive inspection results with 3D point cloud models through photogrammetry and is compatible with various modules to perform different façade operations e.g. cleaning, painting, and pipe installation. The current robot system has been verified by 5 site trials, supported by our industrial partners. We would welcome the opportunity to collaborate with you!
