After taking apart the drone, we needed to build a new motor arm for one of the motor mounts that had snapped. To do this we took measurements of hole sizes and locations, and distances for the motor, and then created a hand sketch of a motor arm. After completing the hand sketches we created a CAD drawing on NX. We used this CAD drawing, got peer feedback, and revised it. After we were sure the CAD drawing would turn out well, well we sent it to a software called CURA. CURA is a splicing software that would help us 3D print our part. We 3D printed our part using PLA material and tested it on our arm, which turned out very well. Pictures of the finished product are included below. The only thing that didn't work out well with our design was that the mounting screws on the arm could not go all the way through the arm and out the other side due to a lack of holes on the bottom. The screw was still able to hold on the mount firmly, but if it were subject to vibrations, the scre...
On September 6, 2023, my lab partner, Stephen Korff, and I flew a Skydio S2 drone to explore the cinematic functions available. We flew at the Purdue University Turf Farm located at 1340 Cherry Ln, West Lafayette, IN 47907. This flight was to also get used to flying the Skydio S2 drone as it was both of our first times operating on this platform. I tested out the motion track, fixed track, and orbit cinematic functions of the Skydio. My partner and I worked together and I would film him using the drone. Motion track was a function that would follow an object and film it, and it would always stay on one side of the object relative to its motion. For example, if programs the drone to follow behind the object, the drone would adjust its position to always be following the object from behind, even if it changed direction. The Fixed Track function would also follow an object as it moved but it would always stay in the same relative location to the object. For example, it could track an...
In this week of class, we started working with the software ArcGIS Pro and looking at maps with different characteristics. We started off by discussing reflectance bands for different colors, including Red Edge and Near Infrared (NIR) as shown in Figure 1. Figure 1- Reflectance bands including blue, green, red, red edge, and NIR We then explored multiband composite rasters. We used the composite tool to take multiple single-band rasters and create a multiband raster. If satellite imagery is given in individual layers, you could use this tool to combine the layers. We then started to adjust the RGB settings. This is where you assign a color to each band of reflectance. You can make it look realistic or edit the colors to be whatever you would like. We took a give picture of a forested area and adjusted these RGB settings by making Band 5 red, Band 3 green, and Band 2 blue. This changed it to look like Figure 2, where you can see the green areas are now pink. Figure 2- Adjusted RGB We co...
