Hardware Overview• Autopilot Control Board- Serves as common platform for

other components and has autopilot code and flight plans• Battery- Powers the board and servos as well as motor• Modem/Antenna- Facilitate communications• Ground Control Station- Used to control UAV midflight• GPS- Used for altitidue and positioning to waypoints• IR Sensors- Determines control movements• Motor and Controller- Manages the motor functioning• Servos- Adjust control surfaces

Autopilot Control Board (Tiny)

• The main control board is the Tiny v2.11 is the brain of the UAV and controls:• Servos (via Pulse-pulse-modulation)• Infrared sensors• GPS• Any applicable payload (CAM)

• The autopilot is released by and updated by the Paparazzi development team

Battery

• 2100mAh 11.1V Li-Poly battery• 6.1 – 18 VDC autopilot input voltage

Datalink Radio(Modem & Antenna)

• Autopilot – Groundstation communication• Serial channel

GPS Receiver

• Receiver & Antenna built into autopilot• uBlox LEA-4 serial receiver – 4Hz update

GPS configuration

• Proprietary control software

IR Sensors

• One x-y sensor + one z sensor• Each axis is a thermopile pair• Differential output from each pair

IR Sensor Modification

• Driven by 3.3V instead of 5V• Changes amplifier gain• Replace biasing resistors for unity gain

Motor & Controller

• Brushless motor and electronic speed control

Servos

• Hitec HS-55 servos

Payload

• We never officially implemented a payload, though this would not require extensive work

• Ostensibly, we would have added a camera to feed back images or video over the modem

• Due to data transmission rate limitations (9600 baudrate) any video taken would be of very low quality, though images could certainly be sent at a decent frequency

• Payload would likely be placed on the side of the modem transmitter beneath and partially embedded in a wing
