AT209 Lab 3: Soldering

 Creating a lap joint via soldering:


The first step is to strip the wire to make the last 1/4 inch of the wire exposed metal. Do this on both ends.

Next, you need to heat up and clean the soldering iron.

You then have to coat each end of the stripped wire in melted solder wire. You do this by taking solder wire and putting it onto the soldering iron to melt it. Then simultaneously put the end of the electrical wire and the end of the soldering wire onto the soldering iron in the puddle of solder. This makes a nice thin coating of solder on the end of the electrical wire.

Once you do this with both ends of the electrical wire, make another puddle of solder on the soldering iron, and stick the two ends of the electrical wire together, dip them both in the puddle at the same time, and quickly pull the ends out.

Pull the electrical wire ends away quickly and the solder will cool and harden, connecting the two ends together.

The connection should be a filleted connection, not a round connection.

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...
