Abstract
This paper presents a heliport for industrial multi rotor helicopter which is possible to exchange battery automatically. Recent years, study of multi rotor helicopter is active in all over the world and it develops for practical use is in progress. In our group, we develop multi rotor helicopter named Mini-Surveyor, and we are trying various studies. However, flight time of multi rotor helicopter is as short as 10 to 15 minutes because most of them are drive by lithium polymer battery. So, in order to extend the flight time of the multi rotor helicopter, we develop autonomous battery exchange system. We have developed an automatic battery exchange system than before. But it is directed to small multi-rotor helicopter, so payload is too small to operate using some device and there was a problem in landing system. So now, we develop new automatic battery exchanger. This new system is developed based on old system, but when the multi rotor helicopter take off and land, it performs accurate take off and land at battery exchanger using by the Vicon system which is high accuracy positioning system. In addition, we develop transportable heliport system which is consisting of autonomous battery exchanger, Vicon system, generator and others. It is designed to be able to operate multi rotor helicopter and battery exchanger in long time at dangerous place such as disaster cannot stay a person and it is possible to operate the multi rotor helicopter only the heliport system. Here we report design of heliport system including autonomous battery exchanger and discuss autonomous takeoff and landing from the heliport.
