When using the Gladius mini s, we encountered two major challenges. The first thing that became immediately evident to us is that the drone cannot do lateral movement like all aerial drones. this basically meant that when we observed the submerged walls we had to constantly change the position of the drone to maintain a vertical view of the walls. Such maneuvers require a lot of coordination and, in our case, resulted in the lifting of mud from the surface, reduced visibility and, finally, the blockage of one engine.
Another challenge we encountered was the position of the lighting that shines directly in front of the drone. The lighting is strong, but it would be better if it landed at a certain angle, because the way it lights up now, it additionally illuminates all the impurities in the water that get in the way of navigation.
Gladius mini s is really perfect for teaching and for high school students. We use it in robotics classes. It meets all the basic needs, but it would be great if there was an SDK so that students could develop the software themselves and if there was a universal port so that students could connect accessories they make themselves, for example on a 3D printer.
