Developing a robust inspection system for internal inspections of small culverts

Tuesday, June 10, 2025
4:45 PM – 6:00 PM MT
Abstract: This research means to develop a non-proprietary wheeled robot system for the use in the internal inspections of small culverts down to a 24-inch span, with collected data as an additional data-based viewpoint to assist the New Mexico Department of Transportation (NMDOT) in asset management. Culvert inspection data is vital to maintaining the functionality of the roadways in New Mexico; and internal inspections allow for a comprehensive understanding of the condition, or “health,” of a culvert. The system in development has already proven effective to inspect with live and recorded video feed up to 100 feet into a 24-inch diameter circular culvert. Further work is being done to improve the functionality and ease of use for the system. The wheeled robot described in this paper is outfitted with two separate first-person-view (FPV) video systems, which allow for robot movement and inspection camera movement to be controlled separately by two inspection personnel. The system created provides for the synchronization of power supplies for the functions of movement, wireless transmission of live video, and retrieval assistance. With the alignment of the required power sources, alongside an optimization of the already sturdy video transmission system, a comprehensive system can be completed. Storage of all the inspection video data for each culvert allows for further data analysis and post-processing of the collected data.

Learning Objectives:

Attendees can expect to learn the following from this session:
  • Upon completion, participant will be able to conduct internal inspections of small culverts via a wheeled robot.
  • Upon completion, participant will be able to describe the limitations and advantages of wheeled robots for use in internal culvert inspections.
  • Upon completion, participant will be able to evaluate the versatility of internal inspections of small culverts in real-time via a wheeled robot and video transmission system.
