The market of mobile robot is increasingly expanding and the function of robot diversifies. Robot cleans room, educates children, guards home and so on. As a result, the power which robot needs is increasing. So many mobile robots need the recharging for its working. During recharging, robot can’t work and this is a serious defect especially in security. To solve this problem, this study suggests a docking station for battery change. At docking station, robot changes its discharged battery to charged battery autonomously. We design a docking mechanism and battery changing system by using axiomatic design. Docking mechanism compensates for offset error and orientation error without actuator. Battery change system change discharged battery to charged battery by using simple mechanism and two motors. We make a 3D model and simulate the model. The model changes battery successfully.
