AT209 Lab 2: DJI Parameters, ATTI Mode Flight

Lab 2: DJI Parameters, ATTI Mode Flight


To edit the parameters of a DJI Mavic 2 Prom from a Windows PC, the first step is to download the DJI Assistant App onto your computer. You then want to locate the file named "main" in the DJI Assistant download by going from:

"This PC > OS (C:) > Program Files (x86) > DJI Product > DJI Assistant > AppFiles > Main"
















Then you must open the JavaScript in a separate application, my choice was Notepad++. Open Notepad++, hit file > open > and find the file "main" that was just located. Once this code is opened, locate the line that says "// Open the DevTools." Delete the two "//" from the line below it. It should look like this:





















You then want to open up the DJI Assistant Application, find the resources tab > local storage > file:// > debug, and double click on the number zero and change the value to "1".
















You can then plug the drone into your computer and click on the "DJI Mavic Pro" button. You can close out of the debug window by hitting the x and then hitting "ignore" on the popup. You can then scroll down on the menu on the left-hand side of the window and pick "parameters". In the "filter" search box, type in "fswitch", find the first result that has a value of 12 and change the value to 3.















This changes the "tripod" mode on the controller to be "attitude mode" instead. So now with the drone we can manually put the drone in ATTI mode.

Flying the drone in ATTI mode proved to be a different kind of flying, and made it more difficult to precisely control the drone. When there was no input on the controller the drone would hold a flat and level attitude instead of holding its GPS position, which meant it would be affected by the wind. Thus, whenever the controller was let go of, the drone would start drifting with the wind. This meant we needed to have more manual wind correction for the drone, which is not too difficult in and of itself, but if we were to try and do multiple tasks at once with the drone in ATTI mode things would begin to get difficult.

UAS Teardown: 3D printed Motor Mount Final Product

Image
 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...

Criminal Location Search (AT309 Week 11)

Image
In this lab, our lab groups met at the Boys and Girls Club in Lafayette to conduct a hostage mission. By the time my group was scheduled to arrive, we had moved our operation outside. The purpose of this lab is to test the capabilities of completing search and rescue work with a drone. We had one person flying the drone trying to locate hostages in high visibility vests, and the other partner would follow the drone, being a visual observer. We found this activity to be relatively unsuccessful because it was time-consuming and the visual observation would spot the participants hiding well before the drone could. It was also taking place in a very confined area. By the time my group was conducting the mission, we had started hanging the vests up in the trees and we had to take a picture when we found them. Figure 1 shows an example of finding the vest in the trees. Figure 1- Vest Location

AT209 Lab 5 Wind Speed vs Battery Life Measurement

Image
In this lab, we used Mavic 2 Pro drones at different altitudes to conduct measurements on wind speed by comparing battery life of the drones hovering in place. Methods: The first step in this lab was to gather our supplies. The class members in lab got partners, and each partner group got a Mavic 2 Pro drone, landing pad, and two or more fully charged batteries from the Purdue Dispatch Center. We then headed to coordinates 40.44364180047488, -87.03272783607103. We set up the drones with landing pads in a row, spaced 5 meters apart. We each had different assigned altitudes so we lined up in order of increasing altitude, south to north. The altitudes for all of the partner groups were 3m, 25m, 50m, 75m, 100m, and 121m. My partner and I flew at 75m AGL. We set up and pre-flighted the drones on one battery, and when everyone was ready, we switched the batteries to a new fully charged one and started up at the same time. We then all took off and flew to our assigned altitudes while facing t...
