Abstract/Summary
The report documents and justifies team LEGION’s senior design project, from research and ideation to prototype manufacturing and testing. It begins by providing some background on the project and outlining the mission scenario given by NASA. This is followed by related literature on excavation of icy regolith on the moon, water transportation, lunar environment, and space law. Next, research is performed into existing products, such as patents and various designs from previous related NASA competitions.
After providing the relevant background information, focused objectives are outlined, with a problem statement, boundary sketch, and engineering specifications. The wants & needs of NASA are considered through a Quality Function Deployment (QFD). An engineering specification table is put together to ensure that those wants and needs can be quantified and achieved in a senior project class timeline.
Elaboration on the ideation process and alternative concepts are discussed, concluding in the chosen concepts, with justification on how those decisions were made and how objectives would be reached using these concepts. After this, a detailed description of the final design for the NASA challenge as well as for the testing build is presented. Following this, the report documents the manufacturing and design verification plan for the build. Manufacturing includes the sourcing of materials and a step-by-step documentation of the building process, and design verification includes the prototype testing procedure and the analysis and conclusions made from the testing data.
Finally, a timeline of the project, key milestones reached, and list of deliverables are introduced. Conclusions and recommendations are provided to reflect on the overall experience and potential steps moving forward.
