GrabCAD
This it's a concept of an Open Source project which has the purpose of create a Drone design supported by the community.
My idea was to create, with the power of this platform and thousands of engineers, a 3D printable drone design.
One of my ideas was adding a 360 degrees camera which is rotated by DC Motors around the Drone. That, and all the electrical parts like the propellers engines will be controlled by the Raspberry Pi, which would have the software developed by the community.
All the people who wants to collaborate on this project can submit all kind of models and ideas to improve and to perfect OUR design.
