The testing process was a long, but meaningful process. The tests relied on numerous tools such as a ruler, camera, backpack with weights, weighing scale, protractor, stop watch, excel, and the operator. There were many modifications along the testing phase, but for the most part, these issues were solved. The following table illustrates the task, testing comments, test methods, and the results.

Each task represents each requirement for the pneumatic leg extension. The testing comments column explains the purpose of the task and how the device may be improved, after analyzing each test. The test method column illustrates what tools or testing method was approached. Finally, the last column demonstrates the results for each testing. Some tests were visual tests, which produced qualitative results, while the rest produced quantitative results.  

Even though the device did not achieve its purpose, the tests illustrate success for the most part of the project.  There were manufacturing issues that lead to struggles through the testing process. Some of these struggles were overcome, others were not as simple. For example, the device can be weight-reduced, but the cost of the device cannot be changed, unless there is a design change. Overall, the tests well highlighted the devices’ qualities and things that need to be redesigned to improve the prototype.
