Generating CAD models for parts is incredibly useful for several reasons: namely assembly, FEA simulation, and data sharing. CAD modeling software allows you to create individual parts, and then assemble them to see how the components will fit together and even how parts will move around each other. It also allows for stress simulation for certain CAD modeling softwares such as Solidworks, which is what our team will be using. Further, Solidworks parts can be directly imported into FEA simulation software such as ANSYS to conduct fluid flow analyses and stress analyses of critical components. Lastly, CAD modeling software expedites the process of creating engineering drawings, allowing one to potentially create many drawings in one day. Engineering drawings are then used in production to establish the standards by which parts should be created.

Model 1: Sonar

Various views of our first concept Sonar can be found below in Figures 1-4. Figure 1 shows the top view of the vehicle, and the large, flat surface for carrying payload. In Figure 4.4 the undercarriage of the vehicle is shown. This is where all the machinery will go. From these perspectives it is impossible to see the wheels, so an angled view is shown in Figure 3. Lastly, Figure 4 shows the hub assembly, the motor bracket which holds the motor in place, and the funnel attached to the fan. For our prototype, the funnel will end up looking somewhat different because it will be made of cardboard and taped to the fan.

Figure 5 below shows the exploded view for our first concept to help demonstrate exactly how all the parts will fit together during assembly.

Change and progress are two words that define my character and my ultimate goals. I have a vision to bring a global change by targeting the psychology, because that is the easiest to change. My aim is to incur a self-progressive routine for myself and then help the people around me to progress themselves. In my perspective, walking towards a defined target should be everyone’s goal while keeping in mind that things don’t go as planned but still the target should remain unchanged.
