An Updated Culvert Inspection Vehicle: HIVE-II

Proper inspection of small culverts can prevent roadway failures, traffic disturbances, and save tens of thousands of dollars on costly repairs. The Vermont Agency of Transportation (VTrans) has adopted a policy which requires all culverts to be inspected every five years. Because of this, approximately 9,600 small culverts must be inspected annually. In this report, a lightweight inspection vehicle is designed to enable efficient and affordable small culvert inspection. This vehicle is designed, built, and tested to meet a list of requirements generated by the Vermont Agency of Transportation. Optimal settings for video transmission through small culverts are understood through theory and a series of field tests. Vehicle form factor is chosen for maneuverability through small, flooded culverts. Finally, performance for drop inlet inspection scenarios is characterized and discussed.
