This large octorotor is developed as part of my master thesis at the University of Southern Denmark where I'm studying a MSc in Robot Systems
The octorotor is part of a system for weed detection in crop rows, where a camera on the platform is taking images of an agricultural field and an on-board embedded computer, running computer vision algorithms, is used to detect the position of the weed and the crop. The system should help reduce the amount of herbicides that is needed to prevent the weed in the field.
I know that a much smaller multirotor could have been used instead, but the platform is meant to be used for other projects afterwards, where heavy professional camera and sensor equipment could be carried by the drone for research and student's projects. A payload of at least 3 kg should be possible, or maybe even higher!
