LAB 04

Lab 4- Systems Analysis 

The team worked on several projects last week including writing a code that would allow the teams AEV to run until the gate, downloading data from the AEV to the automatic control system, and writing a program in MATLAB that would allow the team to convert EEPROM Arduino data into more manageable data. Converting the EEPROM data was done by using the parameters set in lab documentation, as seen in the Appendix. Being able to convert the EEPROM Arduino data into manageable information was important because it gave the team the ability to analyze the efficiency of their AEV and determine areas they would need to work on to make their AEV more efficient. This will also be important in Week 6 because it provided the team with the ability to analyze data collected from the AEV.

As seen in the figure above, phase 1 provided the AEV the most amount of power output during its initialization. This means that the starting up of the motors caused a huge increase in the power. This is due to the first part of the code, setting all motors to a power setting of 55%. From there on out the amount of power created from the AEV decrease significantly at 2 seconds. This is amount of power continues at a constant rate as the code runs the second line of the code, moving to absolute position of 510- shown as phase 2. Phase 3 shows that the power decreases to zero at 10 seconds when the code

Code 
motorSpeed(4,55); // Set’s all motors to 55
goToAbsolutePosition(510); // Runs the motors until the position of 510 marks is reached
break(4); // Turns off all motors

Team Meeting Notes Week 5 

Date: 2/16/2017
Time: 6:00 pm
Members Present: Cat, Emily, Lovell
Topics Discussed: Progress Report Week 5, AEV, Portfolio, Data

Objective:
The objective of this meeting is to break up the parts of the Progress Report after analyzing the AEV data. The other objectives are to update the portfolio and prepare for next week’s lab.

To do/Action Items:
-analyze data
-split parts of progress report
-decide on portfolio parts

Decisions:
-the data is finished and ready to be analyzed
-parts of progress report are split evenly
-portfolio will be done by the time of the next lab

Reflections:
This meeting was very short and unproductive due to the fact that some members had other priorities. The reason for inability to take time to spend together is because the members only had one night to finish everything because the data was collected the day prior.
