Outline• Project overview • Project-specific success criteria• Block diagram• Component selection rationale• Packaging design• Schematic and theory of operation• PCB layout• Software design/development status• Project completion timeline• Questions / discussion
Project Overview• Android controlled quadcopter• Bluetooth connection (~300 foot range)• GPS, compass, ultrasonic, battery monitor• Brushless DC motors with speed controllers• PWM input flight controller board for stabilization• Waypoint navigation & auto take-off/land
Project-Specific Success Criteria• An ability to determine the position of the
quadcopter using GPS• An ability to control the copter using an Android
device over a Bluetooth interface• An ability to automatically take-off and land• An ability to fly-by-waypoint using GPS coordinates• An ability to monitor the state of battery charge and
relay back to user
• Microcontroller– 5 PWM, 1 SPI, 3 UART, 4 A/D– Spare ports– Speed and flash not a constraint
• Peripherals– 3.3 volts– Physical size– Bluetooth – range (~300ft)– GPS – accurate, interference– Magnetometer – motor interference
Component Selection Rationale
Component Selection Rationale• Microcontroller (PIC24FJ256GB110)
– 3 SPI, 3 I2C, 4 UART, 9 PWM, 16 A\D– 16 Bit– 85 I/O pins, 100 pins total– 8 MHz Internal Oscillator– Good documentation and support
• All peripherals on 3.3 volts• All peripherals on breakout boards that are small enough

Software Design/Development Status
• Development with PIC24FJ128– No Peripheral Pin Select (PPS)– Ordered PIC24FJ256 with PPS Plug-In
Module (Thank you Joe!)• UART practice (RFID)• Heartbeat, Reset, Bluetooth, Proximity• Android app developed• Software flowchart (very modular)
