Project Outline

The main objective of this project is to become familiar with the AT90USBKey board, the I/O architecture of the microcontroller, and its software development tools. We are given an ultrasonic range finder, three dc-motors, an analog joystick, and a bi-directional radio transceiver. Our task is to fly an autonomous blimp. By varying the speed of the left/right motors, we can control the direction of the blimp and by varying the speed and direction of the up/down motor, the blimp can maintain a constant height. For this project, we will be controlling the blimp movement manually by a remote joystick. Our tasks were as follows:
