AT 409: Field Report Week 6

Class Lab Report:
Lab this week revolved around research for search and rescue. We met at Purdue Wildlife Area, and set up a ground station for the locating team. The locating team consisted of flight crew 1, and the crew 3, us, were the flight team. Weldon oversaw this lab and hid the missing person. The objective for this lab was to do as many simulation flights as we could with our inventory of batteries. The Mavic 2 Pro flew the rescue missions autonomously while running Loc8. Once the mission finished the SD card was collected out of the Mavic, and the locate team started processing the images for spotting the missing person. There were two forms of processing for the locating team to use, manual search or Loc8. Both forms use the RGB color spectrum to spot the missing person’s clothing. This color spectrum differentiates between the color of the clothes and the color of the grass and plants. Manual searching was the mission’s primary form of processing, whereas Loc8 was a convenient backup. Both forms of locating the missing person, interestingly, went back and forth between which spotted the person first. Once the locating team found a potential hit on the missing person, whether it be found manually or through Loc8, a retrieval team was sent out to bring the missing person back. We had no false indications with either form of location. 3 missions were conducted until the batteries on one of the locating laptops died. The main goal of this lab was to understand the flow of how communication between the chain of command works in a rescue operation, while also finding the most efficient ways to conduct a rescue mission.
Hardware:
DJI Mavic 2 Pro, laptops, iPad, landing pad
Software:
Loc8, Measure App, DJI GO 4
Human Factor:
Given such a large crew, communication could easily get out of hand with side conversations and jokes getting in the way. We allowed ourselves to enjoy these conversations in times when important communications were slow, such as when Weldon was hiding the “body” and when a small team was sent out to find it, or when data was being transferred to the laptops after a flight. We were pleased with the ease of the mission as we coordinated the flights and data transfer and processing. Given our experience with higher difficulty platforms, the Mavic did not provide any challenges we weren’t capable of meeting and it allowed the crew to fly the missions without issues.

Weekly Crew Flight Report:
This mission was completed on October 2nd. The flight crew met up in the lab in NISW around 3 P.M. We went through the necessary checklists to set up the M600 for our mission at Martell Forest. The leaves had begun changing color by the time of this flight, and we knew that the crunch for data collection had started. With a few flights under our belt as a crew we felt prepared to collect data with the M600, and we did so successfully during week 6. Both flights went off without a hitch and we were in and out of Martell in good time. After flying, we returned to Niswonger for data processing.
This week was a turning point for our crew as we saw the evidence of autumn in the leaves and knew that our flight’s success was important to the success of the entire capstone.
Hardware:
M600, Extra Battery Case, PPK, Flight Pad, Sony A6000, Zenmuse XT2, iPad, iPhone (hotspot), landing pad
Software:
Measure App, iPhone Wifi Hotspot
Human Factor:
Our crew continued to bond and enjoy our time together as we conducted this mission. Our communications were clear and our use of the checklists were done as needed. This week saw us getting into our routine with each member knowing what their job was without being told, and having a good sense for each other’s body language during setup and teardown.
