In recent years, wheeled mobile robots and wheeled mobility vehicles have become increasingly popular, and it is important to analyze the phenomena between the rotating wheels and the road surface in order to understand the safety and driving performance of such vehicles. On the other hand, it is difficult to simultaneously observe and analyze the phenomena between the wheels and the road surface simply by attaching rotation sensors or acceleration sensors to the wheels. In this study, we develop a wheel behavior monitoring system using an ultra-high-speed active vision that can precisely capture zoom images at 500 fps around a fast-rotating vehicle. Its effectiveness is verified by showing experimental results of Wheel deformation behavior and rotation behavior under impacts such as the moment when the wheels of a running Segway collide with a deceleration bump and the moment when it drops to the ground and bounces.
