전기동력 무인지상차량의 추진시스템에 관한 연구

This paper deals with the propulsion system and the driving performance of 7 seater UGV(Unmanned Ground Vehicle) using 7kW AC motor which is powered by secondary battery. The UGV has been developing to provide unmanned shuttle service for visitor at the place such as pleasure ground or science museum or amusement park. The size of prototype is about 4m(L)x2m(W)x2.3m(H) and the weight is about 1ton. The prototype uses SLA battery(Sealed Lead-Acid battery) for secondary battery that can supply 16.2kW electric power. Results of driving test, it is noticed that the prototype can be controlled with speed of 0~15km/h.
