Data Analysis
Lab4a
The data Arduino EEPROM was collected from lab4 by running one fourth of the trials. The Arduino EEPROM data was collected in its own units and converted into physical parameters using MATLAB. Figure 1 below shows the energy supplies in change of time.
Phase 1 shows the acceleration of AEV in 0.1 secs, which could quickly accelerates to the goal speed. Phase 2 shows the distance AEV went in constant speed 25%. Phase 3 shows the time and power cost when the motor breaks by the Arduino code. Figure2 below shows the graph of broken phases. The plot reacts the commands clearly.
| Phase | Arduino Code | Time(s) | Total Energy(J) |
| 1 | reverse(4);
celerate(4,0,25,0.1); |
0.0s -0.1s | 1.0633 |
| 2 | motorSpeed(4,25);
goToAbsolutePosition(275); |
0.1s – 7.3s | 718.8704 |
| 3 | break(4); | 7.3s – 10.3s | 2.6488 |
Table1:Phases breaking down
The figure below was break into three phases. The three phases shows steps of different codes of Arduino using in AEV’s test run. The table above shows the break point of phases, the Arduino code using for each phases, the time of the phases and the total energy cost for each phases.
Lab 4b
The two plots are using the Test_data.mat giving under the AEV_Analysis_Tools file, and which did not match the data which we collected. The first plot shows the relationship between the power used in change of distance, and the second plot shows the relationship between power used in change of time. From formal Lab 4 time, team K finished recording data through MATLAB and saved the data into an excel file using codes which is given. Unfortunately, by miss reading the Lab Manual of Lab4b, team K only recorded the data through MATLAB but not through the AEV Analysis Tool. Team K asked GTA Omar and talked to do so. For the further lab, team K would also use AEV Analysis Tool to collect data.
Figure 3 above shows the plots of the power consumption levels in change of time. As the graph shows, power increases as time goes, and being constant when time is approximately at 2.4s. As in Figure 1 it shows the power is more likely to be constant while implementing goFor() command.
Figure 4 above are similar to FIgure 3. Power quickly increases and stabled at about 5.3 Watts as AEV starts to run. Power mostly stabilized. When electronic motor brakes, power returns zero and back to 5.3 Watts again when motor restarts. From Figure 1 above, power stabled at about 6.0 with some fluctuation.
