John Marbut is an Aerspace Engineering student from Embry Riddle Aeronautical University (Prescott, AZ), who is currently participating in the UAS7 Study and Internship Program. Mr. Marbut applied for the UAS7 program in February 2015 and was selected for a Study Semester at Munich University of Applied Sciences (Wintersemester 2015/2016), as well as for a hands-on lab internship at Hochschule Bremen City University of Applied Sciences (Sommersemester 2016). We recently learned that John Marbut’s time in Germany had been spectacular and full of adventures so far since he has had the opportunity to join a research team from UAS Munich to Ecuador in November 2015. In the following blogpost John Marbut writes about his experiences in mapping the Ecuadorian rainforest.

I was lucky enough to get the opportunity to join a research team and senior thesis project at the Munich University of Applied Sciences, the major focus for the project was mapping the Ecuadorian rainforest. The group was actually invited to do the mapping through their partnership with Amazonica who works with the tribes to help improve their quality of life by improving education and providing medical supplies. The planned project required us to modify the UAV/Drone (it can fly autonomously or via remote control) from the last AUVSI competition. We needed to be able to get high resolution photos of the rainforest in order to be able to generate a 3-D map of the area we flew over, so the team installed a new payload containing more batteries, room for the camera, and an infrared trigger to start the camera. The antenna used to update the information about the drone’s had a range of about 5 miles, however the autopilot could fly without making contact with the homebase and the drone had a maximum flight time of just over an hour. The picture above is from our last flight in Shartamensa, home to some of the Achuar tribe.

The second row from the left is myself, I don’t know the name of the two tribe members, then Mascha Kauka, Domingo (President of Shartamensa), Dr. Siebold, and Dr. Krzystek. In the last row is Fabian Braun, Christoph Oberndorfer, and Jonas Wilhelm (Image: Hochschule München)
We left for Ecuador in early November, leaving early in the morning we took a fifteen hour flight from Munich to Quito where we met with our guide Mascha Kauka. After another day of traveling we finally made it to Shartamensa. We had chosen November because it is the dry season for the region that we were mapping. We were able to use the village’s empty hospital as a staging area for the assembly, it took a day to get everything setup. The second day in Shartamensa we started to doing test flights, we found that after about 2pm the rainstorms roll in which makes flying impossible. The third day I joined the Geoinformatics team on a trek into the rainforest to the big tree which stood at about 60 meters tall. We pushed through a swamp and had to hack through the underbrush to get there but the tree was absolutely incredible to see. The tree was about the size of a car and towered well above the normal canopy. The Geoinformatics laid out a gps points that made the mapping for the area accurate down to a few inches. We managed to get back to the village just before sun down and prepped for our second trip the following day.
On the second day of exploration we left quite a bit earlier and so we actually had lunch at a temporary camp that was set up just off the river. The flights went really well, we only had a couple of hard landings but the damage wasn’t too bad. The stay was actually incredible pleasant, we got to see a lot of the Achuar culture, including a lunch on the river, demonstration of their formal greetings, and we got to try a lot of local food. Some of the more unique food and drink was cauim (a traditional type of beer) and roasted grubs. We got to take a trip to a sacred waterfall which is visited anytime the village is struggling. They believe that washing your hands in the waterfall can cleanse your soul. On our last day we spent time with some of the locals playing volleyball and soccer and participated in a cultural exchange between the team and the village.
After the week in the Amazon half of the team returned to Pujo while the second half remained in the Amazon to track down the aircraft after a failure occurred in the autopilot causing the UAV to go down 2 kilometers into the rainforest. Those of us who went back stayed in a city called Baños which is well known for its volcanic hot springs. We spent a day in Baños and waited for the other half of the group to join us before heading to the hot springs. We actually got the opportunity to see a small eruption as we headed away from Baños. We wrapped up the trip with a few days in Quito checking out the Equator, the Equator park, the crater, and the Basilica. The city was beautiful and I would love to go back. My understanding is that team might be going back map the Galapagos, and I encourage anyone who is going to Munich next year to try and join the team.
