Historically, several wheeled robots have been deployed on the Moon and Mars to conduct detailed exploration of the planetary surfaces. However, all of their traversing speeds are restricted to a few centimeters per second, thus covering only a limited area each day. To overcome this limitation and enable wide area exploration, our research group has developed a high-speed rover test bed to advance research on high-speed rover exploration on challenging terrains. The rover is equipped with a hybrid suspension system that combines a rocker mechanism and independent spring-damper suspension for each wheel to reduce vibrations at high speeds． To evaluate the effectiveness of this suspension mechanism, we conducted indoor experiments in which the rover overcame step-shaped obstacles using various suspension configurations.
