Future Tasks:
- Future Plans for AEV design and testing
AEV Project Meeting #15: 10/18/17
In attendance: All teammates
Location: 18th Ave Library
Time: 8AM – 10AM
Topics Discussed:
- CRD draft and distribution of work
Future Tasks:
- Receive Parts, Refine and implement parts in AEV design
- Friction/ Tension Testing

- Motor Speed Testing
- Payload Testing
AEV Project Meeting #16: 10/27/17
In attendance: All teammates
Location: HI 308
Time: 8AM – 8:55AM
Topics Discussed:
- AEV Construction completed
- One Motor mount pulley has hollow interior required hot glue for correct implementation in design.
- Preliminary Test performed to see if pulleys can turn belt.
- Found that motor speed must be at least 50% for small response from system.
Future Tasks:
- Meet Sunday and modify design, receive rubber belt for AEV design.
- Run additional Tests and find optimal belt tension and motor speed.
AEV Project Meeting 10/30/17
In attendance: All team members
Location: Hitchcock 224
Time: 8:00 AM – 9:20 AM
Topics Discussed:
- Latest AEV design iteration constructed.
- New design is made for 3 motor configuration in order to deliver more power to the belt.
- Note: Motors 1 and 2 should be turning in the same direction and motor 3 should always be opposite of motors 1 and 2 because it is the middle motor.
Future Tasks:
- Awaiting AEV parts, preparing for initial AEV testing.
AEV Project Meeting 11/1/17
In attendance: All teammates
Location: 18th Ave Library to HI 324
Time: 8:00 AM – 9:00 AM
Topics Discussed:
- Finally received all the necessary AEV parts to begin testing.
- Preliminary AEV testing
- Discovered that with two motor configuration: minimum movement speed is 25%
- Belt shakes aggressively and almost slips off pulleys above 40%
Future Tasks:
- Continue testing on monorail in next available lab time.
- Begin testing 3 motor configuration
AEV Project Meeting 11/3/17
In attendance: All teammates
Location: HI 308
Time: 8AM – 8:55AM
Topics Discussed:
- Did initial on the rail testing with AEV.
- AEV minimum operating motor speed is 30% for constant movement. Below this speed the AEV will come to a stop.
- Minimum initial motor speed is 40% to overcome static friction.
- Tension in belt must not be too small or too large in order for the AEV to work properly.
Future Tasks:
- Prepare for Committee meetings and additional testing.
AEV Project Meeting: Committee Meeting #2 11/7/17
In attendance: All teammates
Location: HI 224
Time: 8AM – 9:20AM
Topics Discussed:
- Important discoveries learned from day of performance tests: Motor slippage in pulleys, variable belt tension, AEV sensor problems, stability problems.
- Committee meetings: Same assignments as usual: Mike and Roo – R&D, Orfilia – Marketing, Tanner – HR
- Discovered during the R&D committee meeting that AEV sensors measure negative marks for relative position when travelling in reverse.
Future Tasks:
- Fix the problem of poorly printed motor pulleys by drilling out pulleys and gluing propeller “holes” inside of them in order to make the pulleys fit better on the motors – Mike
