Floor finishing installation system using autonomous robots

Autonomous Floor Finishing Installation System

This technology is a system where multiple autonomous robots (for coating, loading, transporting, installing, and charging) collaborate to install floor finishing materials. It features precise positioning using 3D localization devices and active markers, as well as a high-precision installation mechanism based on vision-sensor-driven obstacle avoidance and floor surface recognition.

Relying solely on manual labor for the transport and installation of increasingly large and heavy construction materials results in low work efficiency. Existing remote-controlled robots are limited by the operator's line of sight, making fine adjustments difficult, and the high rate of human error on construction sites poses significant safety risks.

This technology establishes an autonomous robot swarm control system. A 3D localization device transmits positional data to the robots via active markers, while a manipulator structure—combining floor-sensing sensors and vertical/horizontal arms—precisely installs finishing materials according to the floor's coordinate system. By improving the efficiency and safety of material installation on construction sites, this system can also be adapted for rehabilitation training, gait assistance, and various medical and welfare services.

Key Features:

• 3D localization device that recognizes the position and orientation of multiple active markers installed on the job site using vision-integrated distance sensors
• Vertical arm attached to one side of the horizontal arm, operating in an up-and-down motion to install floor finishing materials
• Work-oriented vision sensor mounted on one side of the vertical arm for moving and installing floor finishing materials
• Multiple floor-imaging sensors that recognize the shape of the floor surface where adhesive has been applied to a uniform thickness
