Ordering quadrirotor

We have plans to order the quadrirotor in several ways.
First, we will introduce a joystick to operate the aircraft saw or via a video board.
Thereafter the drone will be autonomous and will be conducted with the help of a GPS chip embedded.

Order by JOYSTICK

To order by joystick, we procured a joystick in a vieu solderie (10 €):

This joystick is a 3D joystick that means it can have the X and Y movements of each standard joystick, but also a movement Z (rotation of the handle on itself). Ceci va nous servir à controler le lacet. This will help us to control the yaw.

As regards the gas, they will be assayed through small potentiometer located on the base. The different buttons on the base will be used for example to perform the reset of the various electronic components (peak emission module ...).

After removing all the electronic cards found inside, we reperons yarns of different knobs that we will need.
We recupere therefore 8 son (6 for the 2 and 3 lines for gas).
These potentiometers 100k, we will use it to create an analog signal that we will use in a peak 16f628.
Once the various converted into digital signals, we send out series on the peak which is connected to the entrance of a module emission and reception HF, the Xbee PRO (ZigBee):

This module has a range of 1.5 kilometers in open fields, a power to issue 60mW max.

Several antennas are proposed, but the solution we have chosen is an external antenna type wireless router connected via a cable adptateur.Cette solution is the best to win a maximum of reach. .

These modules are very easy to communicate with each other and configure

The electronic card that we are going to make will be fed via 2 lithium-ion elements which will provide a voltage of 7.4 v and a capacity of 2.2 Ah (recovery of laptop batteries)
We calculated a theoretical consumption of 370mA that gives you an autonomy joystick around 6am.
