Tanner's Senior Project
R/C Baja
Schedule
Fall Quarter:
Fall quarter consists of three categories of work with various subcategories for each. The first thing that was worked on was the proposal writing report category. The proposal writing report was updated in the winter and spring, but the core writing work was done in fall quarter. The writing report section consists of intro, analysis, methods, testing, budget, schedule, project management, discussion, conclusion, drawing, and appendix. The second category was analyses for different components and aspects of the R/C car. These analyses determine things such as stresses in components, minimum lengths and heights of components, deflections, etc. The final category is documentation. Documentation was provided for the front shock tower, the rear shock tower, shock suspension, and suspension arms.
Winter Quarter:
Winter quarter consists of manufacturing, design revisions, and minor additions to the senior project paper. The expectation is to have 33% of manufactured parts completed by week 3, 66% of manufactured parts completed by week 5, 100% of manufactured parts completed by week 7, and full assembly completed for working device by week 10. Throughout this process there will need to be design revisions to CAD drawings that change throughout manufacturing. Additionally, as ideas modify throughout manufacturing it is expected to be documented within the senior project paper.
Budget
Fall Quarter:
To complete the overall assembly of the car, some parts needed to be created and other parts needed to be purchased. Purchasing these parts helped ensure that the R/C Baja design was optimized and would fulfill all the design requirements necessary for the R/C Baja competition. Currently there are at least 12 purchased parts. The only outsourcing needed at this stage of the project is the use of the 3D printers in Hogue Hall at Central Washington University. The cost to use these 3D printers is $0.50 per hour. Knowing this it can be assumed that the cost to manufacture the parts needed to build the R/C car should not exceed $20.00. Labor for working on this project will be $20.00 per hour for 100 hours of work. The estimated labor cost will be $2000. The labor costs for the 3D printing is $0.50 per hour at approximately 40 hours to print. This brings the labor cost to $20.00 to 3D print at CWU. Total labor cost adds up to $2020. The estimated total project cost is $2045. This project was funded by the members of the project. The total cost was divided evenly amongst the two members and paid for with their personal fund.
Winter Quarter:
During the manufacturing stage of this project there were some changes made to the budget. Some manufactured parts were superseded by purchased parts. This made the new total 20 purchased parts. The manufactured parts material was donated for both the 3D printer and the 6061 aluminum. This made the new overall total $2184.70 including costs for labor and fasteners.
