Refine Block Diagram.

Notes:

Control System Components:

Autopilot Example:

http://www.sparkfun.com/datasheets/GPS/EvalBoards/ArduPilot-v15.pdf

IMU example:

http://www.sparkfun.com/products/9268

Brush-less Motor Control example:

Other Sensors: IR / Sonar(?) barometer(?) airspeed(?) temperature(?) additional gyro(?) accelerometer(?)

TODO>>make sure atmega can handle everything we need.

On-board Computer:

H/W: https://www.gumstix.com/store/product_info.php?products_id=256

Or a cheaper alternative that can interface with a camera, and stream video over Wi-Fi and can talk to the Control Board via serial (SPI)

S/W: Embedded Linux: http://www.openembedded.org/wiki/Main_Page

TODO>> justify of the shelf component. (integration of required memory components under the time / weight / budget constraints is impossible)

Power Bus

Different voltages for Boards and Props.

Low power indication / emergency landing.

TODO>>calculate power draw.

Ground Station:

Should look like : http://code.google.com/p/ardupilot/wiki/GroundStation

TODO>>specify requirements and interfaces.

Example Software Stack:

Great place to find parts (with weights specified)

Ex: brush-less motors:
