摘要

The Virginia Tech Mars Auto-Deployable Rover System (MARS) Team has been researching and exploring multiple methods of collapsing and expanding a rigid structure from a packed configuration in an expanded configuration. The purpose of this work is to develop the concept of an expanding rover for NASA's manned Mars mission. A rover of this nature would save valuable payload volume during launch. This concept poses a substantial, open-ended engineering problem. A thorough concept development process led to an initial design, the semi-cylindrical rover concept that deploys in two directions. Multiple iterations of FEA models were created with increasing complexities to obtain a viable solution that minimized mass while still having the ability to safely handle the applied loading. Combining results from FEA analysis and concept generation, two prototypes were assembled with varying functionality to showcase the feasibility of the design. Using these two prototypes, subsequent testing will be conducted to verify the functionality and performance.
