Abstract:

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 ODOT 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 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.
