Eye In The SkyTCSP #4

-Team 3 Joe Katz Upsham Dawra Samit Sura Ashwin Shankar

Project Overview

o Portable low-cost aerial drone that can be used for reconnaissance

o Relay real-time video and data, like location, heading, battery life

o Take high-resolution pictures of the ground in flight

o Store photos and some flight data in non-volatile memory, á la “blackbox” system.

o Control drone manually via a control unit

The Microcontroller

•AtmelAT32UC3A256•Voltage required = 3.3 V•Satisfied all the design constraints

DC Convertors - LTC 1174Voltage Supplied by Battery = 11.1 V

3.3V required for:•Microcontroller•IMU•GPS•Compass•Xbee Pro•SD card

5V required forVideo Transmitter

I.M.U. – MPU6000

•Communicates via I2C•Voltage required 3.3V

GPS Module – MT 3329

•Required Voltage = 3.3V•Will communicate via UART

Servo Motors

•Power was originally already supplied from plane battery•Will be controlled via PWM

Digital Compass – HMC 6352

•Communicates via I2C•Voltage required 3.3V

Xbee module

•Communicates via UART•Voltage required 3.3V

SD card

•Communicates via SPI•Voltage required 3.3V

DS 2438 – Battery Monitoring

•Communicates via SPI•Special circuit because monitoring voltage >10V
