In this study, the effect of a vacuum environment on the traveling characteristics of planetary rovers is experimentally investigated. For this study, a wheel traveling test system that enables a wheel to travel at various speeds and traction loads in a vacuum chamber was developed. In this system, the ground can be prepared before each run, and the wheel can travel in similar ground conditions repeatedly. Subsequently, using this system, traveling tests of the wheel were conducted in the atmosphere and medium vacuum. The wheel was tested at different speeds and various traction loads (i.e., drawbar pulls) on a sandbox filled with three types of material. Wheel slip and sinkage were quantitatively compared in the atmosphere and vacuum. From the experiment, it was confirmed that the medium vacuum environment does not significantly affect the traveling performance of the wheel.

在这项研究中，实验研究了真空环境对行星漫游者行进特性的影响。为了进行这项研究，开发了一种车轮行驶测试系统，该系统能够使车轮在真空室内以各种速度和牵引载荷行驶。在该系统中，可以在每次行驶之前准备好地面，并且轮子可以在相似的地面条件下反复行驶。随后，使用该系统，在大气和中等真空下进行了车轮的行驶测试。在装有三种类型材料的沙盒上，以不同的速度和各种牵引载荷（即，牵引杆拉力）对车轮进行了测试。在大气和真空下定量比较了车轮打滑和下沉。根据实验，
