It is important to investigate the underground of the planets in terms of the elucidation of the planet's origin and a development of the bases that human can work on the planets. Therefore, we have developed a planetary subsurface excavation robot with peristaltic crawling mechanism. This robot consists of two units; a propulsion unit and an excavation unit. The propulsion unit has three subunits using a peristaltic motion. The excavation unit has an earth auger. But, the existing robot can't excavate without a discharging unit because the soil isn't smoothly discharged from a spout when it reaches below surface. So, we develop a discharging unit to solve this problem. Then, we have an excavating experiment with the robot in order to check the capacity of the discharging unit. Thus, we confirmed that the robot could discharge the soil by the discharging unit.
