Your capstone design team is prototyping (e.g. you are building a model to test not a final product) a "fire identification drone. The final product is intended to fly over rugged wilderness areas and look for small fires that should be monitored and potentially fought or contained. It is NOT intended to be used in large active fires. Your subteam's job is to design and build the support frame for the drone (e.g. the structure where the motors, propellers, guidance electronics and GPS, heat sensors, radio receiver and transmitter, etc. are attached) for the prototype. You have access to a machine shop with saws, lathes (for removing material by rotating it and using a cutting tool), drills and a facility with 3-D printers that can print a variety of plastics using fused deposition modeling (this is the technique where a polymer filament is melted and forced through a nozzle to build a structure layer by layer). You will be testing in a summer/fall timeframe so you expect temperatures to be in the 5- 40°C (41°F-104°F) range. As a conservative estimate, you are assuming that all the electronics will have a mass of 250g. Your job is to identify TWO different materials from the table below to propose as materials to use to build the support frame. Select one material from the table below that you believe would potentially make a good urone frame that you could prototype given a machine shop or 3-D printers. Explain why you chose the material in 2-4 bullets. Would you shape this material in the machine shop or using 3-D printing. Explain why in 2-4 bullets.
