Meeting 15

Date: 8 – March – 2019                            

Time: 9:35-10:55

Members Present: Larenz Coles, Tara Maynard, Brittany Shine, & Allan Thomas

Location: Hitchcock 224

Objective:

Complete Performance Test 1 and use additional time to finish aR&D 2.

Topics Discussed: Lab 11

  • Larenz volunteered to code the performance test
  • Tara calculated the number of marks to reach about 4 ft from the gate (to allow for extra space)
  • The first two trials went too far past the gate because the AEV coasted for longer than expected
  • The third trial stopped at gate but rolled backwards
  • Larenz changed the amount of time the propellers reversed
  • The fourth trial successfully stopped at the gate
  • Larenz continued to code the AEV to stop for 8 seconds (with an additional second for safety because gate takes 7 seconds to open)
  • The team tested the AEV and prior to asking UTA to grade; AEV successfully passed performance test 1

To Do/Action Items:

  • Prepare for extra lab time
  • Finish aR&D during extra lab time on Monday, March 18 at 6:30
  • Work on individual parts for Progress Report and Website Update (All – Mar 19)
  • Begin planning for Oral Presentation

Reflections:

  • Without using the physical break, the AEV needs plenty of time to coast before stopping
    • Just because propellers stop doesn’t mean the AEV does
  • Changing the amount of time the propellers reverse can control how quickly the AEV stops and prevents the AEV from continuing to roll backwards
  • The code will need to be changed if a physical break is implemented
