Despite the success so far accomplished in the robotic exploration of the Moon and Mars, the constraints associated with newly proposed mission concepts manifest the need for a faster surface prospection. Increasing driving velocities is being considered as a potential solution to the requirements introduced by these missions. This review presents the benefits and foreseeable challenges of using faster locomotive solutions for space exploration. Information is provided regarding the set of missions that would benefit most from faster locomotive capabilities. Starting by understanding the theoretical framework governing the interaction of wheeled robots operating over loose, sandy terrains, we delve into the foundation of Bekker's classic terramechanic equations—the most frequently used method to predict mobile robots off‐road performance. We highlight its limitations and review the efforts that have been made to expand the range of application of these theories to dynamic wheel–soil interactions. We analyze the existing experimental evidence on the effects of increasing traveling velocities under earthbound, off‐road conditions. By paying special attention to previous experiences on the lunar surface, we outline the challenges that the combination of irregular terrains and a reduced‐gravity field may pose to a fast‐moving exploration rover. The principles, mathematical models, experimental evidence, and experiences presented in this review are meant to aid in the identification of poorly understood and insufficiently studied aspects regarding high‐speed extraterrestrial surface mobility.

行星表面上的高速移动性:技术回顾

尽管到目前为止在月球和火星的机器人探索中取得了成功,但与新提出的任务概念相关的限制仍然表明需要更快的地面探测。不断提高的行驶速度被认为是解决这些特派团提出的要求的潜在解决方案。这篇评论介绍了使用更快的机车解决方案进行太空探索的好处和可预见的挑战。提供了有关任务集的信息,这些信息将从更快的机车能力中受益最大。从了解控制在松散,沙质地形上运行的轮式机器人的相互作用的理论框架开始,我们深入研究了贝克尔经典的土力学方程式的基础,这是最常用于预测移动机器人越野性能的方法。我们强调了它的局限性,并回顾了为将这些理论的应用范围扩展到动态轮土相互作用中所做的努力。我们分析了在大地,越野条件下行驶速度增加的影响的现有实验证据。通过特别关注月球表面的先前经验,我们概述了不规则地形和重力场减小对快速移动的探测漫游者可能构成的挑战。这篇综述中提出的原理,数学模型,实验证据和经验旨在帮助识别关于高速地球外表面流动性的认识不足和研究不足的方面。
