Project Overview

• The goal of this project is to create a
  helicopter capable of flying itself. The
  helicopter should be able to take off, fly to a
  predetermined location, and land without user
  input (during flight). The target will be
  specified pre-flight by a user, through a
  computer interface.

Constraints

• Weight
• The sensors, transceiver, and power supply must
  be as light as possible, since they will be
  onboard.
• Power consumption
• Trade-off between flight time and weight of
  batteries
• Trade-off between wireless range and power use
• Trade-off between navigational accuracy and
  microprocessor speed (sensor data transmission)?
• Sensor/Control delays
• Trade-off between sensor sensitivity, size, and
  speed
• Activation speed of servos is our limiting factor
  in adjusting course

Systems

• Computer with Bluetooth
• Interpret sensor data/calculate and maintain
  course
• Transceiver Class 1 Bluetooth Radio
• Send formatted sensor readings to the PC
• Receive control signals from the PC
• PIC Microcontroller/ADC/DAC
• Collect/Format sensor readings prior to
  transmission
• Convert/split control signals prior to sending to
  servos
• Gyroscope Sensor
• Read rotation around rotor axis
• Accelerometer Sensors
• Read acceleration in X, Y, and Z directions
