I have been a part of the UAV R&D team. The team simultaneously dealt with the development of different kinds of UAVs and experimenting with off-the-shelf solutions. Working tasks included flight simulation, integration of different sensors, implementation of the control algorithms, and preparation of the field experiments. I have a vast experience in preparing UAV field tests, either from the mechanical and electrical side. Some of the filed-work related tasks included full UAV assembling, wiring, retrieving data logs, and analyzing flight results in combination with controller parameters refining.
