Customer Handoff & Final Project Documentation
Table of Contents
Team Vision for Final Demo and HandoffTasks Accomplished:
- Built the four sails for imagine RIT
- Completed poster for imagine RIT
- Completed lighting video showing overview of project and final deployment test
- Resolved issues with Genva Cam getting stuck:
- Added spacer to lower the motor shaft and prevent the measuring tapes from getting caught on the top of the shaft
- Added a spacer to keep the measuring tapes from falling when they are coiled around the spindle
- Added lubrication to the whole Genva Cam mechanism
- Sanded Genva Cam fillets on the slots to create chamfers so the pin could be guided into the slot better
- Resolved electric issues:
- Added Step Up Regulator to circuit to overcome h-bridge voltage loss.
- Rewired the circuit and edited the code to be compatible with the step up regulator
Test Results SummaryAll of the test plans described in previous phases have been completed. Although most tests determined that the target objectives were met, there were some that were not. These consisted of the sail size that could come out of the CubeSat being too small, the sensors being unreliable during deployment, and deployment from the CubeSat. All of these issues were discussed with the customer and will be addressed by future design teams or by a higher budget to purchase a thinner sail material. The full test plans and results can be seen here.
Risk and Problem Tracking
Problem TrackingContinuous modification on the problems that arose during the previous phase occurred was the primary focus of the team during this phase. One main issue arose with the use of a voltage regulator to increase the power to the motor. There was a constant drop across the H-bridge, which caused issues that had to be addressed by the team. Problem Tracking
MAA Seaway Section Meeting ConferenceOn Saturday April 14th Michael and Victor traveled to Brockport NY to present the team's project in a student poster session at the 2018 MAA Seaway Section Meeting. The pair discussed both the senior design project and the concepts of CubeSats and Solar Sails to conference attendees for an hour and a half. Although our poster was unique among pure math projects, we met several individuals very interested in our technology. Mike and Victor also gained valuable experience describing the project to fresh ears, a skill that will be invaluable at Imagine RIT.
Final Project Documentation
Technical PaperTechnical Paper
Imagine RIT PosterThe team's poster design was based off of the poster used by the team during the Boeing event in February 2018. The team's final poster, which was used during Imagine RIT, can be found here. This design includes actual photos of the final product, and elaborates more on specifics of the design and manufacturing process than the initial version did. In addition, acknowledgments and other more formal elements were included within the finalized poster.

Plans for Wrap-upTasks to Complete:
- Drill a hole into one of the side panels to allow all the wires to come out for the Imagine RIT exibit
- Finalize technical paper
- Troubleshoot the sensor values during deployment since they are reading incorrectly
- Prepare for Imagine RIT
