Mission.

This is a senior design project being undertaken by three students of the Computer Engineering Department at Rochester Institute of Technology. The project consists of a blimp system that can locate an infrared beacon from a distance. The blimp should be capable of locating the beacon when set off from a distance of 7 meters. Once the blimp gets close to the beacon, it is to land within a 40 centimeter radius of the beacon.

The beacon sends out a 38KHz-modulated signal in a hemispherical pattern, so that the blimp can detect it from any approach. Three IR detectors on-board the blimp will determine the bearing and landing condition. A single ultrasonic ranger is used to sample the altitude. Three independent motors are used to control the altitude, change bearing, and propel the blimp.
