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...
For this lab, my lab partner and I completed a total of 5 3D scans using a DJI Mavic 2 Pro and a Skydio S2+. We conducted 2D mapping missions, 3D object scans, and 3D orbit scans. The purpose of this was to compare the two platforms. 2D Mapping Missions: We first used the Skydio S2+ to conduct a mapping mission of a small section of a parking lot at the William H. Daniel Turfgrass Research and Diagnostic Center. After that, we used the DJI Mavic 2 Pro to conduct 2 scans of the same area- one being a lawnmower grid and the other being an opposing grid scan. Both scans were fairly easy to set up, but the main difference we noticed was that the Mavic 2 Pro was able to set up the scan on the ground using Pix4D Capture, while the Skydio had to take off before it could set up the scan. This makes a large difference in battery life, with the Mavic 2 Pro being more efficient. Specific details on how we set up these scans can be found in the lab report. Figure 1 shows the scan area of the p...
