Abstract

There is a project of Autonomous monitoring system being solved at Tomas Bata University in Zlin. Within the framework of this project a small airship driven by ultrasonic detectors is being developed. This airship shall be capable of independent operation in an enclosed hall, bearing a camera or another monitoring system. There are several voltages needed to power the circuits of the airship. To ensure their feeding from a Li-Pol battery, a small and lightweight power supply has been designed. In this article, aspects of designing such power supply unit are analysed. Some attention is also devoted to the wider aspects of using the airships, mainly their advantages of low power consumption, and to the circumstances of employing the developed circuits.
