The microcamera case should be connected to the microdrone arm support, the white component in the slideshow below. The two-parts arm-support has the advantage to be oriented and locked in different azimuth positions between 0 DEG (ground alignment) and about 60 DEG.
A well known limitation is that, due the very reduced size of the microdrone (about 14×14 cm) it is also reduced its payload weight so it is was excluded a priori any sort of automated camera movement control. Instead the stabilization of the video shooting is reached with rubber supports.
Another problem found during tests is setting the camera to the most vertical position (60-70 DEG). Due the unbalanced weight between the lenses body and the rest of the circuit when the camera is in a quasi-vertical position the drone tend to be unbalanced on the front side. This problem can be solved in two ways: adding a variable-length back queue to the drone body with the advantage of right balance and more stability or – a more complex solution – moving the camera second-half arm support almost in the same position of the lenses body.
The drone legs should be changed as the camera body increase the total drone height. A temporary solution, as shown in the images, has been found adopting commercial plastic hose clamps. These will be replaced by a carbon-fiber flexible and very lightweight part under construction.
