Autonomous Blimp - Stage 2 + Final Report

The Video
2nd Stage: Joystick Remote Control + auto-Height Adjustment (PID)
3rd Stage: Autonomous Control: Tracing Light Source

 It can now maintain height by using PID control on sonar data.

Autonomous Blimp - Stage 1

joystick controls 3 propellers to go forward/backward, up/down, or to turn and spin.

It uses atmel at90 board, a/d for reading the joystick positions, and pwm for driving the motors.

3 stages for this project:

1. Joystick controlling motors, polling loop for inputs
2. Mount motors on the blimp, wireless radio remote control and data transmission, sonars, Real-time OS, RS-232
3. Fly freely in a building by itself, from one end to another landing on a light source( w/ light sensors), gryos, accelerometers...
