An ergonomic and design review of the Lunar Terrain Vehicle

Abstract

Through a literature study, this paper examines the lunar rover ergonomics and design from an industrial design perspective, considering the history of the lunar rover, the astronauts' experience, human factors, sustainability, and rising industry standards.By analyzing the upcoming missions, the terrain, and previous rovers, this paper identifies a set of criteria and proposes a concept for the seating design of the next-generation lunar terrain vehicles, focusing only on unpressurized vehicles.The Lunar Terrain Vehicle requires a human-center design process and an understanding of the astronauts' critical needs during the operation. The seating needs to accommodate the suited astronauts, restrain the astronauts without interfering with their mobility, and provide stability during the traverse. The industry expects the new vehicles to last in extreme environments for many years; the new design must be lightweight, durable, and practical.Despite being subject to change by many influencing factors out of the designer's control, this paper presents a unique process emphasizing the ergonomics and usability of the astronaut that can serve as a guideline for future lunar rovers for exploration and commercial purposes. The proposed design concept provides safety and comfort to the astronauts during the EVAs while accommodating the environmental requirements.The industrial design perspective in this study highlights the benefits of a multi-disciplinary approach in the space industry. Beyond exploration, the human space flight endeavor demands more than functionality. The future of spaceflight is sustainable, safe, and more human-centered than ever.
