The supporting force that the leg of the rover is received is increased when vibration imparts to the ground. This phenomenon improves the running performance of the legged rovers. This study investigates the change in the supporting force by vibration in low atmospheric pressure. The atmospheric pressure of the Mars and Moon are lower than one of the earth. This environment affects the characteristics of ground sand because the air resistance is decreased. This study offers valuable information about using vibration in planetary exploration to improve the running performance of legged rovers. The experimental results show that the supporting force in low atmospheric pressure is almost the same as one in standard atmospheric pressure. It means that the condition of atmospheric pressure hardly affects the supporting force when imparting vibration.
