Meeting 17

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)
