AEV Improvements

Time: 6:00 pm (Face-to-Face)

Members Present: Alex Beutel, Blake Kanoy, Daniel Fahmi, Ashwin Rajgopal

Topics Discussed: How to improve the AEV

Objective:

The main focus of the meeting was to take the results from the performance analysis, research how to improve the weaker aspects of the AEV, and make improvements to the AEV.

To do/ Action Items:

-Gather and analyze all performance analyses of the lab

-Determine the problem areas and what needs improved on the AEV

-Make desired improvements to the AEV

Decisions:

-Decided to reduce weight by switching the base with a smaller piece of plastic

-Decided to use the T-shaped arm instead of the L-shaped arm

Reflections:

-Changing the base reduced the weight of the AEV and reduced the battery usage due to the motors not having to run as fast

-Changing to the T-shaped arm improved the balance of the AEV and slightly reduced weight

-The AEV was slightly improved, no major improvements were made

Code Finetuning

Time: 2:00 pm (Face-to-Face)

Members Present: Ashwin Rajgopal and Daniel Fahmi

Topics Discussed: AEV Code

Objective:

The focus of the meeting was to fine tune and finalize the code of the AEV so that it would stop at the gate on the track.

To do/ Action Items:

Test current code and ensure that it works

-Research which commands would work to cause the AEV to stop at the gate

-Implement those commands into the code

-Test and evaluate the new code and commands

-Adjust the code if the AEV does not stop at the gate

Decisions:

-Decided to use the goToRelativePosition command in order to stop at the gate

Reflections:

-Researching and testing went quickly and the code to stop at the gate was finished quickly

-Initially tried a combination of start and stop motor commands, but switched to the goToRelativePosition

-The code is going well and there are few to no issues with writing the code

AEV Body Reworking

Time: 2:00pm (Face-to-Face)

Members Present: Blake Kanoy and Alex Beutel

Topics Discussed: AEV Body Design

Objective:

The main focus of the meeting was to adjust and rework the AEV body design to match the concept design that was decided upon in the team meeting on 2/817.

To do/ Action Items:

-Partially deconstruct the original AEV body

-Assemble the decided upon final design

-Inspect the new body and ensure that it matches the design

-Test the new body

Decisions:

-The group decided on the final body design of the AEV

-The group began dismantling and assembling the new body

Reflections:

-The deconstruction took longer than expected due to limitations with tools

-Only having one screwdriver and one crescent wrench limits the ability of the group to work at the same time

-Construction of the new body took longer than expected

-Team did not have time to test the new body and will have to at a later date

Schedule from 2/9 to 2/16
