Variable Wheel Position Mechanism with Full Mobility for a Car-Like Robot

자동차 로봇의 휠 배치 가변 구조 연구

In this paper, an attempt has been made by incorporating variable wheel arrangement for a car-like robot. In this scheme, the car-like robot controls its body height and the length of forward and backward wheels while driving in omni-direction. Experimental results show that the proposed car-like robot with wheel arrangement variable structure presents effectiveness of several situations.(a. left and right turn, b. longitudinal and latitudinal parking, c. control of body height and the length of forward and backward wheels, d. passing over obstacles, e. adaptive cruise control.)
