Concept
Bridge Cable Robot
Cable Inspection Robot is a research project by ArrowDot Company with function to check the quality of cable for bridge which can be used for Neak Loeung Bridge, New Balay Bridge and planned Koh Pich-Koh Norea Bridge. This robot equipped with analyzed camera that can view the cracked point and the vibration level of the cable. Last but not least, this robot can be remote and live up to 500m wirelessly.
