Homemade quadcopter. This was an interative project which went through two versions.
The first version of the quadcopter was equipped with homemade electronics centered around an Arduino nano and MPU-6050 accelerometer + gryo. The frame was built out of carbon fiber. Communication with the drone was achieved using an Xbee module and either a custom made handheld controller or a processing application running on a computer. However, due to difficulties in communicating with the drone such way, version 1 was scrapped.
For the second iteration of this project, the frame was rebuilt with arms made out of aluminium. This provided a less brittle structure. The electronics was replaced with a KK2.0 quadcopter board from hobbyking and a RC transceiver + remote controller which would provide a more reliable way to pilot the drone.
