MiniQuadCopter

Last crawled date: 1 year, 10 months ago

- The QuadCopter is designed with “Rhino” CAD.
- For the size of the copter maybe a shell is better then a skeleton (like a bug).
- With a thin shell, only very little amount of infill is needed in order to connect the outer and the inner wall. I used 12% infill. The weight is between 15 an 19 grams depending on the wall thickness (see table).
- For static reasons and to minimize the weight a tricycle undercarriage is used. Furthermore three legs are better on rough surfaces than four legs.
- The small holes in the legs of the undercarriage can be used to attach the payload itself or the cargo platform.
- The shell with the undercarriage is one part.
- The shell can be printed with FDM-technology without support structures.
- There are flat surfaces to attach the battery and the electronic with Velcro.
- To connect the battery that is located in the shell with the electronics there are two cable channels.
- Some foam rubber should be applied to the undercarriage (minimum thickness of 2 mm).

“Optional components”
- The “canopy” on top of the shell is an option to fix and to cover the electronic components. The connection to the shell is realized with two bolts (removable). The weight of the canopy is around 5 grams (ABS). It is designed as one single part that can be printed without support structures.
- The cargo platform can be used for the payload shown in the description. The weight of the platform is 2 grams (ABS).
