RESULTS
The results showed that the conveyor met the requirement of the unit needing to maintain a speed of at least 3 m/s but not the requirement of the packages maintaining orientation. Unfortunately, there was no consistency in the behavior of packages. The box was launched at different distances on the new angled launcher to see how the package behaved while being diverted onto the 9570 unit at different speeds. Some speeds experienced tumbling while others did not but there was no pattern. Despite the launching speed distance, the exiting speed of the packages did not vary a ton and had a small range of 2.7-3.3 m/s. The smallest range of data at any section on the conveyor.

Results: Project
The graph shows that packages launched at farther distance have a high initial speed but tend to slow down to the speed of the conveyor upon exiting. While the packages launched at a shorter distance the catch up to maintain that 3 m/s. This leads to the elimination of launching the box from a distance of 2 in because it does not satisfy the requirement to have a speed of at least 3 m/s until the third section and would exit at an average speed lower than 3m/s. You can see the range in speed decrease as the box travels across the sections of the conveyor, which shows that the conveyor is regulating the speed of the boxes diverted onto it.
The inconsistent turbulence leads to the conclusion that the diverting speed is not associated with the turbulence the packages experience. A new variable is going to be manipulated and tested to see what could create the consistent turbulence the packages experienced while in the tech center.
​
The results of the this test were not very accurate but were precise from the video camera. The behavior of the boxes was not consistent so no accurate conclusion on how velocity is affecting orientation could be made. The speed range is from 1.55 m/s-5.38 m/s. The varies off the desired 3 m/s by 2.38 m/s. The precision for the calculations comes from the video cameras ability to shoot one frame per 0.003 seconds. The calculations are then rounded to +/- 0.01. As you can see some of these results are not within the target and were eliminated from future testing.
​
The testing was valid because it was set up to best replicate the testing done at the tech center. So the results should have been representative of what was seen in the initial videos, however that was not what the results represented.
​
These results are relevant to the projects success because they showed what parameters can be disposed of for future testing. These results showed that the launching velocity does not correlate with orientation so the results allow for a different variable to be explored. The variable of launching speed can disregarded as directly correlating to turbulence.
