Date: 18 – March – 2019
Time: 6:30-7:50
Members Present: Larenz Coles & Tara Maynard
Location: Hitchcock 224
Objective:
Complete aR&D testing of physical brake using servo motor by taking control and experimental data of power vs. distance.
Topics Discussed: Additional Lab Time
- Larenz uploaded the scenario to the AEV without the physical brake and the AEV was tested on the track
- The data extraction tool was not extracting data, which led to troubleshooting with the UTA
- The Arduino was simply turned off and back on to eventually upload the data successfully
- Slight adjustments had to be made to percent power in code and reversal of propellers to gather needed data until a total of 2 successful trials were complete
- Tara adjusted the T-arm to the other side of the base because the servo reset to the opposite direction as desired
- Tara attached the paper rod to the servo motor arm using zip-ties. Putty was added to increase friction.
- The AEV was tested for another 2 trials using the physical brake
- The AEV stopped immediately
To Do/Action Items:
- Add aR&D to Progress Report 2 (Tara – today)
- Edit Progress Report 2 (All – today)
- Turn in Progress Report 2 (Tara – today)
- Add aR&D to Website Update 2 (Larenz – today)
- Polish and add information to Website Update 2 (Brittany/Allan – today)
- Plan meeting time to practice presentation (All – Mar 19)
- Presentation (All – Mar 21)
Reflections:
- The data showed a spike in data for the control and not in the physical brake
- The AEV did not require time to roll to a stop and instead stopped immediately
- Physically braking is more power and time efficient
- The physical brake should be implemented to better complete the Smart City Columbus mission
- Previous codes must be edited to instead use the physical brake to perform the same duties (ex. performance test one)
