Remote Sensing Direct Measurement Mandrel for Use in Pipes Division of Engineering Research On-Call Services Task 4

The objective of this project was to develop a low-cost Remote Sensing Direct Measurement Mandrel (RSDMM) that can measure the internal in-situ diameter of buried flexible pipe with diameter ranging from 24 in (610 mm) to 48 in (1220 mm). This was achieved by modifying the Ohio Department of Transportation’s Turtle Rover to include a LiDAR and forward-facing camera all controlled by an Arduino controller and a pi-top base station with an Xbox controller. The Turtle Rover was able to communicate to the pi-top via Wi-Fi connected through a provided Wi-Fi-dongle. Laboratory calibration on 24 in (610 mm) diameter high-density polyethylene (HDPE) pipe showed that the LiDAR provided had a resolution 0.039 inches (1mm) and a standard deviation of 0.14911 inches (3.78 mm) when measuring a 24-inch diameter HDPE pipe.
