1. Meece, Adam. Laser Guided Navigation System for the Automated Floor Profiler – String Walker Edition.

Degree: MS, Engineering and Applied Science: Electrical Engineering, 2017, University of Cincinnati

Floor profiling is the process of measuring the flatness and levelness of the floor. These quantities are found by measuring the displacement of the floor in one foot increments, along straight lines. The floor profile is represented by F-numbers, which is the industry standard as per ASTM E1155. FF is the floor flatness and FL is the floor levelness. The objective of this thesis is to develop and introduce a system of devices for efficient navigation for the autonomous floor profiler. This will be accomplished through a new laser guided system for navigation. The system consists of two laser devices for the floor profiler to track on straight line paths and alignment lasers, called String Walkers, and two peripheral lasers, acting as tripwire stopping points for each line, heading sources for movement between lines, and alignment lasers for setup. The String Walkers utilize servos for movement and laser oscillation, as well as IR and ultrasonic proximity sensors for navigation. The final configuration of the String Walker has an estimated battery life over 11 hours under normal operation. The laser guidance navigation system was tested for accuracy in straight-line travelling, as well as autonomous navigation functionality. It was found that the oscillating laser provided consistent signals to the Floor Walker device at all distances by varying the oscillation angle from 1-3 degrees. At the furthest distances, 1° is used, while at the closest distances 3° is used. The String Walker is able to consistently travel between measurement lines with excellent accuracy and precision. Using the String Walker and peripheral lasers for laser guidance reduced the standard deviation from a straight-line path from 0.765” with gyroscope-feedback navigation to 0.224” with the laser guidance navigation system.
